Last week I flew EWR>ABQ on AA. Flight at time of booking was not advertised as a "through flight". (all receipts, etc. show only EWR>ABQ, no mention of a stop.)

Got to EWR to discover it's going through DFW. I check with gate agent and am told that we'll deplane and get on a new plane. (Though a delay made us miss that plane altogether.)

I contacted AA upon my return and was told that they have through flights all the time, and that "there is no planned change of aircraft and the flight number remains the same." First of all how do they not advertise this? Second, since there was a change of plane, why is it still a "through flight" and not a "layover"?

I booked the flight I did (and paid) specifically because it was direct.

Advice? Is any compensation warranted?
