Way to many 50 seaters for dl to even think this statement is true. And far as upgrades go we're coming up on four yrs. Eagle has a lot of pilots flowing to AA so if every thing keeps moving then upgrade at eagle will continue to move, on the other hand the industry can take a hit, and put a stop to that really quick, but your brakes would be put on too. And is mesaba not getting rid of all their 340's?
