That doesn't particularly bother me-- DFW is too short a flight to need the entertainment system anyway.
We ought to make a long list for AA of things PHX needs and hasn't got.
For instance, I would find a redeye flight to ORD useful. The current redeye option, 1:30/2:30am to DFW, is unpleasant to use.
At least seasonal nonstops to MIA would be nice, too.
