It's probably too early to know, but does anyone have any idea what might happen to Take Flight Certificates once AA/US finally combine systems (i.e. will we be able to use them on AA flights? I assume they'll still be valid to at least be used on US Airways)?
I just got a TFC at IAH yesterday when my flight to PHL was overbooked ($425 TFC). They subsequently rebooked me onto the next flight with an upgrade to first class, but that flight was ultimately cancelled due to the ground hold at PHL.
