When AA sees big drops in bookings, they'll know that aa.com hasn't been the place people go to book. If that happens, it won't be long before we see them back on Orbitz and Expedia.
I dont think it will be long before the other carriers follow suit.. Southwest doesnt use that travel model and they dont seem to be having any issues.. now do they?
I used to use the corp travel dept for all my travel.. they would charge my dept dept $20 just to book a ticket.. then if you had an issue with travel after hours its another charge. Forget that.. AA.com works just fine for me. As much as I travel.. I think I am mentally competent enough to figure out if I am being scr*wd on a fare to a location.
