I'm a PHX FO, but I've done a few turns through DFW and let's just say it leaves a little to be desired. On one of those occasions every single Mesa CRJ was grounded for a lav waste compartment AD and we sat for 3 hours waiting for mx to show up.

Envoy ground crews seem to be the other half of the disastrous equation though. At the request of the CA, I went to grab the release and had to talk to three different gate agents to get it. Nobody seemed to know which computer to use or which printer it was sending it to. Passengers all boarded and ready to go but nobody could figure out how to get the paperwork in a timely manner.

Luckily for us AA doesn't give a rats ass about performance or passenger satisfaction, so unless we get really expensive I don't see any of this being a problem.
