Most airliners, regardless of route length, will fly about 3000 hours per year. 737s might do 4, 5 or 6 legs per day. Fuel efficiency is an even larger concern for those planes because while a long haul aircraft will spend most of its working life at cruising speed, the short haul aircraft spend a good amount of time at takeoffs, landings, and lower altitudes, which burn more fuel per passenger/km.
- manquer 6y agoThe difference is not as high as I had originally thought and has been narrowing recently, it is still a substantial number. Currently 7.5 hrs/day [3] for small narrow bodies, 10.09 hrs/day [2] for large narrow bodies and 12.48 hrs/day [1] for wide bodies.
