Air travelers often have preferences when it comes to the type of aircraft they fly on, with many favoring mainline aircraft for their comfort and amenities. However, millions of passengers in the United States find themselves flying on regional jets due to airline scheduling, airport size, and cost considerations.
Mainline aircraft such as the Boeing 737 and Airbus A320 are favored for their spaciousness, better amenities, smoother rides, and more comfortable cabin pressure systems. "The seats have less legroom, and there’s less recline. No question about that; it’s not as comfortable an environment,” says airline consultant Mike Boyd regarding regional jets.
Regional aircraft like the Embraer E175 and Bombardier CRJ-900 serve an essential role by connecting smaller cities to major hubs. Despite their smaller size, these planes are popular with airlines due to lower operating costs and increased flight frequency. According to EyeOfTheFlyer.com, scope clauses can limit passenger capacity and fleet strength to protect pilot salaries at mainline carriers.
