That's been a question as long as I've been with the company. Frontrunners seem to be the 737 and 757, but I've heard that the 73 is too small/slow for a lot of 72 trips and the 75 is too big to fit in the superhub parking spots. So who really knows? I've heard so many rumors that I won't believe anything until I see a new aircraft type painted purple AND parked on our ramp.
