Boeing 777-300 is a passenger aircraft designed for medium and long-haul airlines. The Boeing 777-300 is part of a family of wide-body, twin-engine aircraft, its length is 73.86 meters with a wingspan of 60.93 meters. In terms of passenger capacity and flight range, it corresponds to Boeing 747-100 and 747-200 aircraft, but surpasses them by 30% in fuel efficiency, and by 40% in operational costs, which led to the crowding out of these models by the Boeing 777-300.
The interior of the Boeing 777-300 is made in curved lines, with enlarged luggage racks and indirect lighting. The layout of the cabin allows airlines to quickly move seats, kitchens and toilets, depending on the desired configuration. The configuration of the seats ranges from four in a row in the first class and up to ten in the economy class. Some aircraft are equipped with VIP lounges for charter flights. Portholes of 380 × 250 mm in size are the largest before the Boeing 787. The toilet has been improved - a new hydraulic hinge for the toilet lid has been used, which closes slowly.
In March 1997, the construction of the first prototype aircraft began, and on May 21, 1998 flight tests were completed and the first Cathay Pacific aircraft was delivered. The main customers of the Boeing 777-300 are Pacific Airlines - Japan Airlines, Korean Air, Cathay Pacific, Malaysia Airlines, Russia and others. 60 aircraft were sold to eight airlines. All aircraft are still in operation. However, after the launch of the Boeing 777-300ER extended range model in 2004, all customers changed the order for this modification.
The location and numbering of seats in the cabin, the layout of seats in the Boeing 777-300 aircraft. Better and less comfortable seats on the plane
The business class is located in the bow of the aircraft, accommodates 30 passengers. A comfortable class is located behind the business class, the number of seats is 48, in a 2: 4: 2 layout. With a standard layout in the economy class cabin accommodates about 330 people. Armchairs are usually located on the principle of: 9 seats or 10 seats in a row (3: 4: 3). According to tourist reviews, the Boeing 777-300 is generally a very comfortable airliner.
Best Seats on a Boeing 777-300 in a Three-Class Layout
- From 1 to 5 row of a business class seat - quite comfortable. Each row has six seats in a 2: 2: 2 arrangement. The chairs are wide, comfortable, soft and there is a lot of space between them.
- 11-16 rows of comfort class. The distance between the seats is slightly reduced, however, the location of the seats 2: 4: 2 is not bad. The minus of the 11th row is that the partition in front of the seats is too close and the nearby toilet is located, which can interfere with your peace of mind during the flight.
- 17 row - This is the first row of the economy class, there are no neighbors in the front, so the seats will not be thrown back at you, and you can straighten your legs as you like. Only in this row are the side seats arranged in pairs.
- 18 row, places C and H. There are no neighbors in front, so there is a lot of legroom. These places are located in the middle of the pitching aircraft during the intersection of the turbulence zone will be minimally noticeable.
- 24 row it is located after emergency exits, there are no neighbors in front, but there is a toilet nearby - for some it’s a minus, for someone a plus. When traveling with children, the nearby toilet is very convenient.
- 38 row, just like 24 row - there is an emergency exit and a kitchen room nearby. These places have a lot of legroom.
- 47-49 rows, places AC NK - here the side seats are arranged in pairs, these are convenient places for flying together.
The Boeing 777-300 has places where you can find both advantages and disadvantages. So, places like:
- 12 row, places C, D, G, N. All these places are lateral at the aisle. People will often go to the toilet here, so they can interfere with you, since the aisles themselves are not very wide.
- 20 row, window seats. Some airlines do not have a porthole.
- 23, 36, 50 row - These are the last places before exits, the back of the seats may have limitations or not recline at all. There is a toilet behind, so some fuss is possible, and extreme places can be affected by passing passengers.
There are no really bad places in the Boeing 777. Each seat has pros and cons, but most of all the minuses have:
37, 51 rows - they are located in front of the cupboard and toilet, the walls of these rooms will prevent you from folding your backs completely. In addition, the extreme seats - D and G can be touched by cabin crew trolleys and passengers.
"Russia" - is a subsidiary of Aeroflot. Since April 2016, Rossiya Airlines has been assigning the names of cities of the Russian Federation to its aircraft. On the nose of the fuselage under the cockpit is the name and coat of arms of the city. On the left side of the plane the name of the city is printed in Russian, on the right side in English. There are 5 Boeing 777-300 aircraft in the airline’s fleet, they have the following names and numbers: Yekaterinburg (EI-XLP), Moscow (EI-UNN), Novosibirsk (EI-UNM), Sochi (EI-UNL), Ussuriysk / Leolet (EI -UNP).
The airliner Boeing 777-300 of Rossiya Airlines has a two-class layout: 18 business-class seats, 355 economy-class seats.
Business Class divided into two salons: superior comfort (1 row) and just a business class (5,6 row ) . In the luxury salon, the design is made in classic colors - blue, red, white. Armchairs are very comfortable, covered with leather, have an increased step of 152 cm and are laid out 180 degrees. Business class chairs are laid out at 160 degrees. The backs of all seats are equipped with video monitors with a diagonal of 15.4 inches.
Economy class:
The economy class is divided into three salons easy to design: from 21 to 35, from 36 to 48, from 49 to 61 rows. The seats are standard, quite comfortable. The backs of all seats are equipped with 8.9-inch video monitors. Aisles and row spacing are narrow.
- Between 48 and 49 nearby and before 21 nearby economy class toilets for passengers with disabilities.
- For flights with babies it is better to choose seats AB DEF HK 5 rows, ABC DEF GHK 21 rows, DEF 36 rows or ABC GHK 50 rowssince they are equipped with mounts for baby cots.
- Seats 21, 36, 49 rows located behind emergency exits, resulting in these places with increased legroom. If the neighborhood with toilets does not bother, then these are good places.
- 35, 48, 61 rows less comfortable due to limited backrest adjustment. But places BA and KH double, not built. For travelers, a couple is a kind of convenience.

Thai Airways
Thai Airways has a fleet of six Boeing 777-300 aircraft. For flights to Russia, a two-class configuration is used, accommodating 34 seats in the business class and 330 in the economy class.
Business Class:
- Business class takes five rows and starts 11 to 16 rows. Armchairs are conveniently laid out, their width is 51 cm, the distance between the rows is 155 cm. This class has the most varied menu and quality service.
- 11 row located right behind the partition, there are mounts for baby cots, so for flights with babies - this is the best option. For the rest of the passengers occupying these places, a septum in front of the eyes that restricts visibility during a long flight will tire, especially in the middle row, where there are no windows.
- Seats in the 16th row have their own characteristics. Firstly, there is no porthole near the outermost seat on the port side 16A. Secondly, the places are located immediately in front of the two sections of the on-board kitchen, so these are quite noisy places, in addition, the light is on in the kitchen at night.
- Seats AB 31st and DEF HJK 32nd row equipped with mounts for baby cots, so when flying with small children, these are the most convenient places. Also of the pluses, it can be noted that in these places the distance between the seats and the partition is enough to stretch the legs. These places are not very comfortable in terms of: additional noise from children, sounds coming from the kitchen and toilet, a partition before the eyes accompanying the entire flight and one armrest fixed because of the folding table built into it.
- Before place 32C there is no armchair - this is additional space for the knees and legs and a guarantee that no one will throw the back of your armchair on you. Given a long flight, this is very helpful.
- Seats 43 and 44 are the worst places: the backs of the seats rest against the wall of the toilet, which may limit the folding. To spend the entire flight in an upright position is very inconvenient. In addition, the proximity to the toilets can cause some discomfort (vanity, lines, sounds of a descent tank).
- 46 row - this is an almost complete copy 31-32 rows. The only difference is that there is no on-board kitchen, only numerous latrines and an emergency exit block.
- 47 row. Places A and Klocated in front of the emergency exits - you will have additional legroom, however, because of the door a little protruding into the cabin, you will not be able to fully extend your legs. A little inconvenience can bring close proximity to the toilets due to unnecessary fuss. Places B, C and H, J have extra legroom, the seatbacks recline. Of the minuses - the neighborhood with the restrooms. DF Places have fastening for children's cradles.
- Places C and Hin 56 and 70 rows bulging noticeably into the aisle. Passengers at these places may be affected by other passengers or cabin crew with trolleys.
- 58 row located near the on-board kitchen. This neighborhood can be inconvenient.
- 57 and 59 row - seats are located that may have a limitation in reclining the back of the chair. They are marked in yellow on the diagram.
- 60 row only four seats - two on each side of the side. Advantage in extra legroom B and J, and disadvantages in the form of space limitations on the hatch in the field A and K. In addition, the proximity to the kitchen may interfere with relaxation.
- In row 61the distance between the seats is a few centimeters less than in other rows of the aircraft. This must be considered by tall people.
- Seats in row 62 D, E, F completely repeat the layout 32 rows: cradles, wall and proximity to the kitchen.
- But mesta 62 C and H considered comfortable. There is no chair in front of them, there is a good view and there are no toilets nearby.
- 72 row - uncomfortable. The backrests either have a limitation in reclining or are completely fixed. There are lavatories and technical rooms behind the wall, so here, in addition to smells and sounds, queues from visitors are quite expected.

The largest number of these airliners is operated by Transaero (14 aircraft) and Aeroflot (16 aircraft).
The layout of the Boeing 777, the best places for flights, technical specifications - all this in this article.
Short description
This Boeing model is the very first in history, its design was developed in the 90s of the last century without paper drawings, completely and completely on a computer using special programs.
This is the most reliable airliner in the history of aviation, which makes long flights without a single stop.
"Boeing 777" belongs to the wide-body passenger. It has been in operation from 1995 to the present.
The capacity is 305-550 people, flight range - 9 100-17 500 kilometers.
Technical characteristics of the Boeing 777
It is the largest airliner in the world with only 2 engines. These are powerful General Electric gas turbine engines. The landing gear consists of 6 wheels, which distinguishes it from other aircraft.
Consider the technical characteristics of the Boeing 777 for versions 200 and 300.

Interior and interior layout
Boeing 777, as noted above, has several varieties. Salons each of the modifications has 3 or 4 - each has its own layout, which depends on the customer.
The interior of the salons is dominated by curved lines, indirect lighting, wide luggage racks. The size of the porthole relative to earlier is 380x250 mm.
Economy class capacity - up to 555 people. Armchairs are located 10 in a row. Compared to the first Boeing 777 models, since 2011 the interior has been modernized, making it more modern.
In the business class, the seats are located 6 in a row, and they are laid out in a full bed, which is very convenient during long-distance flights. Due to the fact that the total number of seats is less than in economy class, there is more space.
The imperial class is designed for the most comfortable and expensive flights. Increased attention, additional services, the best cuisine - all this for special guests.
The scheme of the Boeing 777-300 cabin of Aeroflot Airlines is presented in the photo below.
The best places on the plane
Depend on the overall staffing of the cabin. When buying tickets, you can choose any place, but it is preferable to find the most convenient so that the flight is pleasant and comfortable.
The best places are located at the emergency exits: there is additional legroom. Convenient places in the Boeing 777-300 are considered to be those located in rows 11-16 - these are places where 3 seats are installed in a row (except for those next to the toilet). Good places are located near the aisle - there is an opportunity for a short while, but with pleasure to spread your legs.
- if the modification provides for double seats near the porthole, then when pairing it is better to choose them;
In economy classes, the closer to the nose of the aircraft, the wider the distance between the rows of seats;
Most shakes those in the tail, least of all - near the wings;
If the airliner is not fully loaded with passengers, then there are fewer people in the tail and, accordingly, more space.
Of course, these are average indicators, since different airlines have their own nuances in the design of the cabin of their aircraft, and it does not matter that in essence it is one and the same Boeing 777.
Transaero
The Russian aviation company Transaero owns 14 Boeing 777 aircraft. Of these, 9 are modifications of the Boeing 777-200.
This company uses configurations, the passenger capacity of which is 306 and 323 people, 4 and 3 classes of salons, respectively.

In Transaero, they are as follows:
Imperial;
Business class (premium);
Economic;
Tourist.
A photo of the scheme of the cabin of the Boeing 777 (Transaero) modification 200 is presented below.
In the imperial class, all seats are as comfortable as possible for flights. There are only 12 seats in the cabin, which can be transformed into a bed if necessary and willing.

It is the world's largest twin-engine jet passenger aircraft. The Boeing 777 set an absolute range record for passenger aircraft: 21.601 thousand km! Boeing 777 ("Triple Seven" or "three sevens") - this aircraft was developed in the early 1990s, made its first flight in 1994, in operation since 1995. The Boeing 777 was the first commercial airliner to be 100% computer-based. And this is the safest long-haul liner in aviation history!
I flew three sevens only once - from Dubai to Male by Emirates Airlines, and then I was surprised to learn that they had saved a lot on the layout of the economy class cabin, put in one row an extra seat reducing the width of the rest! In this report I will talk about the history of creation, design features and show the passenger compartment of the largest operator of this type of aircraft in Russia.
History of creation:
In the mid-1970s. Three-engine 777, which was conceived as a competitor for the McDonnell Douglas DC-10 and Lockheed L-1011. This aircraft was conceived as a modified version of the 767 with a redone wing and tail. It was planned to create two main options: a short-haul aircraft that would be able to carry up to 175 passengers over a distance of 5000 kilometers, and an intercontinental airliner that carries the same number of passengers over a distance of up to 8000 kilometers.
Work on twin-engine aircraft was soon started, but Project 777 was frozen, because there were difficulties with the design of the tail section of the aircraft, and the company also decided to focus on the more commercially promising 757 and 767. As a result, when both machines began to roll off the assembly line, it’s clear that the Boeing line is missing the link. There was an urgent need to have an aircraft that was located in a niche between such machines as the Boeing 767-300ER and Boeing 747-400.
At first, Boeing simply planned to refine the 767, resulting in the concept of the so-called 767-X. It was largely akin to the 767, but had a longer fuselage, a larger wing and could carry about 340 passengers at a distance of 13.5 thousand kilometers.
1.
But the airlines were not impressed with the new aircraft. They wanted to have a plane capable of flying at shorter distances and with a cabin configuration similar to the Boeing 747, which, in addition, could be changed by adding or removing the required number of passenger seats in a cabin of one or another class. Another prerequisite was lower operating costs — they should have been significantly lower than those of the 767. As a result, the initial design was greatly revised and a twin-engine Boeing 777 was born.
The Boeing 777 was the first commercial airliner to be 100% computer-based. For all the time of development, not a single paper drawing was issued, everything was made using a three-dimensional design system.
The development of the aircraft began in 1990 and immediately received the first order from United Airlines. In 1995, the first 777 began operating commercial flights. Currently, the 777-200LR is an aircraft capable of performing the longest passenger flights in the world.

Modifications:
The 777-200 was the first modification of the aircraft and was intended for Segment A. The first 777-200 was transferred to United Airlines on May 15, 1995. At a range of 5,235 nautical miles, the 777-200 was primarily targeted at US domestic carriers. A total of 88 different types of 777-200 aircraft were handed over to ten customers. The competing model of Airbus is the A330-300.

An extended version of the 777-300 was designed to replace the Boeing 747-100 and Boeing 747-200 aircraft. Compared with the old versions of the 747th, the elongated version has similar passenger capacity and range, but it consumes one third less fuel and has 40% lower operating costs. The 777-300 fuselage is extended by 11 meters compared to the basic 777-200 modification, which can accommodate up to 550 passengers in a single-class configuration. The maximum modification range is 6015 nautical miles, which allows the 777-300 to serve heavily loaded destinations previously served by the 747.

777-200ER
Modification 777-200ER ("ER" means Extended Range, increased range). The 777-200ER has an increased fuel reserve and maximum take-off weight compared to the 777-200 modification. Designed for international carriers and transatlantic flights, the "nf modification has a maximum range of 7,700 nautical miles (14260.4 km).
777-200LR
777-200LR (“LR” means “Longer Range” - long range), the model for Segment C, in 2006 became the most “long-range” commercial airliner in the world. Boeing called this model Worldliner, indicating the possibility of an airliner connecting almost any two airports. The modification set a world record for the longest non-stop flight among commercial airliners - the flight range is 9380 nautical miles (17,370 km). Modification 777-200LR is designed for extra-long flights such as Los Angeles - Singapore or Dallas - Tokyo. The 777-200LR has an increased maximum take-off weight and three additional fuel tanks in the rear luggage compartment.
777-300ER
The 777-300ER (“ER” stands for Extended Range, is a modification of the 777-300. The modification has beveled and elongated wingtips, new main landing gear, reinforced front strut and additional fuel tanks. The GE90-115B turbofan engines standard for this model are by far the most powerful jet engines in the world and have a maximum thrust of 513 kN. The maximum range is 7930 nautical miles (14 690 km), which was made possible thanks to the increased maximum take-off weight and fuel reserve. Range 777-300ER with full load increased by approximately 34% compared with the modification 777-300. After flight tests, the introduction of new engines, wings and an increase in take-off weight, fuel consumption decreased by 1.4%.

And all the modifications in the visual range:

A good illustration for comparing the scale is ahead of the 737th. Please note that the diameter of the GE-115B engine installed on the 777 is only 30 cm smaller than the width of the Boeing 737!
11.
Elements of construction:
The design of the airframe includes the use of composite materials, which make up 9% of the weight of the structure. Of these materials, including the floor of the cabin and steering wheels. The main part of the fuselage has a circular cross section and at the rear goes into the blade like a tail cone, in which the auxiliary power unit is located.

The airliner also has the largest landing gear and the largest tires that have ever been used in commercial jet airliners. Each tire from the main six-wheeled landing gear of the 777-300ER can withstand a load of 27 tons, which is more than the load on the tire of a Boeing 747-400!

20.
The aircraft has three backup hydraulic systems, of which only one is needed for landing.
In the wing fairing under the fuselage there is an emergency aviation turbine - a small propeller that extends from the aircraft in emergency situations to ensure minimum power supply.
The General Electric GE90 engines installed on the Boeing 7777 are the largest and most powerful jet engines in aviation history.
And on all five Boeing 777-300 a / c Transaero engines RR211 Trent 892 Rolls Royse engines are installed:

Cockpit:
The cockpit is very spacious. Boeing 777 in all versions is a long-haul airliner capable of servicing non-stop commercial flights lasting up to 18 hours. However, the rules of various aviation regulatory bodies, professional and trade union organizations limit the time of continuous work of the crew and flight attendants.

Interior:
The 777, also known as the Boeing Signature Interior, is made in curved lines, with larger luggage racks and indirect lighting. The configuration of the seats ranges from 4 in a row in the first class to 10 in the economy class. The size of the portholes - 380 × 250 mm - was the largest of all commercial airliners until the advent of 787.
Each passenger company has its own passenger compartment. It depends on the particular requirements of the customer, and not on the type of aircraft!
Please note that in economy class Transaero has one seat less in a row than, for example, Emirates (!) And Aeroflot. And this means that the seats themselves are wider and more comfortable!

Take a look on board the Boeing 777-300 of Transaero Airlines. EI-UNM flew in Singapore Airlines, in 2012 it was transferred to Transaero. The interior is completely updated, the Lumexis entertainment system is installed everywhere. The upholstery uses Alcantara, a wear-resistant material, and the armchair manufacturer is the Italian company Aviointeriors.

Security:
This airliner is considered the safest aircraft among all long-haul airliners. Over 18 years of operation with the Boeing 777, eight incidents occurred, including one accident and two capture attempts. July 6, 2013 there was the first plane crash with human casualties. An Asiana Airlines Boeing 777-200ER flying from Seoul to San Francisco crashed while landing at the San Francisco airport, landing on the tail end of the runway. 2 people died.
Boeing 777 in Russia:
In Russia, the largest operator of Boeing 777 aircraft is Transaero. There are 14 aircraft in the company's fleet: 5 - Boeing 777-300, 9 - Boeing 777-200ER. In addition to Transaero, this aircraft is in the fleet of Aeroflot, Nordwind and Orenair.
