not sure how true this is, but had an airtran on the van in CMH one morning say he left Mesaba back when, for some other crummy regional, and if he had stayed at Mesaba he would be at Delta now on the 76 as an FO, instead hes getting a screw job by Southwest and is fairly JR as an FO now.
I would say if your senior to me, leave, if your junior, stay.
I think its so hard to tell man. We could get merged into the AA list, or even teamed into AA in a merger with USAIR. We could mixed into PSA/Piedmont in a merger. Skywest or anyone else could buy Eagle in exchange for most of AAs flying.
We also could get Comaird and you could sit here furloughing 50 every 3 months till your number comes.
We also could get a large chunk of the bigger planes. AA has had the chance to bid out this flying before on the 50 seat level and has not.
