Propeller airliners often had first class in the rear, away from the noise of the engine and propeller, while a first class on jet aircraft is normally positioned near the front of the aircraft, often in front of the business class section or on the upper deck of wide-body aircraft such as the Boeing 747 and Airbus ...

In the vast majority of commercial aircraft, First Class (or Business Class on international routes) is located at the very front of the plane. This configuration is primarily logistical; it allows premium passengers to board and deplane first, and it places them furthest away from the noise of the jet engines, which are typically mounted under the wings. On "double-decker" aircraft like the Boeing 747 or the Airbus A380, First Class may be located in the "nose" of the main deck or on the entire upper deck. However, there are rare exceptions. Some regional jets or specialized configurations for certain airlines might place the premium cabin in the middle or even the rear to maintain the aircraft's center of gravity. Furthermore, in 2026, some "private" or "semi-private" jet services utilize a single-class cabin where the seating is uniform, but for standard commercial travel, the front of the aircraft remains the "gold standard" for the highest level of service.
