And the reservation was changed again. This time I didn't lose any flights but my SEA-LHR-MAD just changed to SEA-DFW-LHR-MAD adding 5 hours to my trip and making my connection tighter at LHR. There's a BA direct flight leaving at 8pm to LHR, no idea why they added the connection. With the direct flight I'm in London an hour earlier and I leave 4 hours later from SEA.

Anyway, just called them and spent 45 minutes on the phone while watching the Bengals/Bills game. My call was dropped for some reason while they were fixing it (the machine said it was sorry and reconnected me) and I had to start from scratch when they reconnected me. When the new agent tried to fix it, he said he couldn't do it because it appeared someone had locked it--maybe the previous agent working on it. But then the outbound flight was finally fixed by us taking the BA flight. Too bad I can't select my seat now. Well, better than wasting 5 hours at the airport and having a tighter connection.

Edit: my guess is that they canceled AA 156 and moved everyone to go through DFW since the BA flight can't take the load. When I changed it, it only had 3 business class tickets left. I guess people will find out late and won't be able to get the BA flight.
