Yesterday, I booked a last minute PIT-ORD-GRU-GIG flight. Since PIT-ORD was full in First, I was ticketed Y/D/D. No problem.

When I realized I wasn't going to make it to the airport, I switched online to PIT-IAD-GRU-GIG. However, even though there were F seats available on PIT-IAD, my new ticket remained Y/D/D.

Now, I believe this is the way CO has always done things like this, but I was wondering if PMUA had a smarter system that would have switched me to F/D/D which I would have gotten had I done the original booking through IAD. Or if I should expect any changes in the future.

I suppose an agent could have fixed this for me, but I didn't want to call while madly driving to the airport. And by the time I called after checking in, they said only the gate agent could help me. Again, no big deal, since I ended up #1 on the UL, was upgraded, and it was only a 30 min flight anyway. I'm just curious about the system's flexibility for future travel purposes.
