I don't claim to be an expert in terms of bankruptcy operations, but wouldn't it be counter-productive to just park 70 (est.) airplanes and thereby eliminate revenue? My personal feeling is that this bankruptcy was thought through a long time ago, and Eagle would not have been hiring full speed this long if airplanes were to be parked and not replaced with something else. I am sure there are some unprofitable routes that will be culled, but AMR could have parked the airplanes a long time ago with no consequences even before we were so overstaffed. I just have a hard time believeing that with this opportunity to reduce the labor costs that management has wanted for so long that they are just going to throw away a fully-operational airline (Eagle) in exchange for an unknown feed. So far at least there has been no announcement about capacity reduction beyond the regular 4th quarter stuff.
Also, my understanding is that hiring/classes are technically "on hold" which means they can be resumed at any time. Let's not forget that Eagles' plan was to bid on outside flying and if costs are reduced through this process (I am not advocating this as a good thing) then it is very possible that Eagle will not shrink at all. Let's not panic until we see what we are dealing with.
