  • Originally Delta uses 772LR to fly between ATL and JNB, but all Delta's 777s will be retired after COVID-19, and with the raise of A359's MTOW, it can fly the route in the future.

Why 757 is "heavy"

In US:

  • Super: A380 (MTOW of 575 t) and An-225 (MTOW of 640 t)
  • Heavy: MTOW >= 136 t (almost all wide-body aircraft + 757)
  • Large (FAA): MTOW between 19 t and 140 t
  • Medium: MTOW between 7 t and 136 t
  • Light: MTOW less than 7t

The MTOW of 757-200 is 116 t, but it became "heavy" after accidents where smaller aircraft following closely behind a 757 crashed.

Why regional aircraft has 50 or 70 or 76 seats?

AA, Delta, United have contracts with pilot unions to limit the number of regional planes they can operate:

This is why most of US regional flights are 50 or 70 or 76 seats; this is also the reason of CRJ 550, which is a re-certificated CRJ 700 with only 50 seats, because United had reached its limit of 76-seat airplanes.
