None of the airlines that comprise American Eagle have their own sites anymore, as they have all been merged into one wholly owned subsidiary of AMR.
The former TWA Express carriers are NOT part of Eagle, but are flying under the banner "American Connection" feeding mainline AA with the permission of AMR. The people at American Eagle (who by contract are supposed to be the only mainline AA feeder) are VERY unhappy about this. AMR is screwing over their own, because they can get these other carriers to do it cheaper. While I hate to see anyone else out of a job, I also resent my flying being contracted out to another company while I am furloughed as an Eagle pilot!
