Alas, it makes great sense, they already have a dedicated flight attendant training center, why on earth would you send them somewhere else?
I know the tax dollars and local revenue will be affected. But honestly 200 so people isn't going to desimate anything in the local economy. The hotels in the area are almost always full, honestly there needs to be another 10 hotels near the airport. I have to say though you must not spend a lot of time at the training center you have 4 regional airlines doing pilot training there as well as the AA pilots. The cafeteria there won't downsize, its packed at lunch and not with flight attendants. Not sure what you think will happen to the rest of the employees...there is still plent of work to be done there.
Now if AA dehubbed CLT we could be in trouble.
Also you said 152 people would be affected, thats probably pretty close to the entire centers employee group, so with only the flight attendants leaving they aren't going to lay off the entire work group.
