Concept
Aircraft cabin
Summary
An aircraft cabin is the section of an aircraft in which passengers travel. Most modern commercial aircraft are pressurized, as cruising altitudes are high enough such that the surrounding atmosphere is too thin for passengers and crew to breathe.
In commercial air travel, particularly in airliners, cabins may be divided into several parts. These can include travel class sections in medium and large aircraft, areas for flight attendants, the galley, and storage for in-flight service. Seats are mostly arranged in rows and aisles. The higher the travel class, the more space is provided. Cabins of the different travel classes are often divided by curtains, sometimes called class dividers. Passengers are not usually allowed to visit higher travel class cabins in commercial flights.
Some aircraft cabins contain passenger entertainment systems. Short and medium haul cabins tend to have no or shared screens whereas long and ultra-long haul flights often contain personal screens.
Business class is almost replacing first class: 70% of 777s had first-class cabins before 2008 while 22% of new 777s and 787s had one in 2017.
Full-flat seats in business-class rose from 65% of 777 deliveries in 2008 to nearly 100% of the 777s and 787s delivered in 2017, excepted for low-cost carriers having 10% premium cabin on their widebodies.
First-class seats were halved over the past 5–10 years, typically from eight to four.
To differentiate from business class, high-end first class move to full-height enclosures like Singapore Airlines, Emirates, and Etihad.
Business class became the equivalent of what first class was a few years ago.
In 2017, 80% of the 777s and 787s delivered had a separate premium economy with one or two fewer seats across than regular economy class.
In economy class, slimmer seats with composite frames and thinner upholstery can add legroom or allow more seating.
While ground or more often satellite internet connection is available at lower cost due to competition, only 25–30% of carriers outside U.S. offer inflight connectivity.
