I searched through 7 pages of the most recently updated Skymiles threads and couldn't find this. A couple of days ago, I saw someone posting about NWA/DL pulling e-tickets from other airlines and wondered if anyone (I think Jaimito Cartero posted in that thread), could shed some light if this is still possible.

I'm flying to SFO tomorrow on AA. They screwed up and left me without a seat assignment on a full flight, and unable to check in. If this is not fixed when I get to the airport (i.e., I don't get a seat assignment), my best alternative would be to fly JAX-ATL-SFO or JAX-MSP-SFO roughly 30 minutes later (via DL, of course).

If the need should arise and AA gives no seat assignment, do I just walk up to DL and ask them to pull the ticket? I'm not willing to roll the dice on IDB overnight if I can help it.

Thanks in advance.
