The airplanes become denser than ever and sometimes I feel so uncomfortable during long flights. Surprisingly, airlines are not offering the same legroom in their airplanes.
The picture below compares the legroom between the U.S. airlines, including Jet Blue, Virgin America, Southwest, Delta, American, United, and Spirit. The numbers are measured on 2 common aircraft, the Boeing 737 and Airbus A320.
The winner is Jet Blue with 34 inches.
