Ok, I just signed up. The first thing I wanted to check was upgrade availability for a DFW -> ANC flight I want to book.
So I enter in the time and date (7/19/2005) and get the following:
AA 278
DFW 07/19/2005 04:39PM
ANC 07/19/2005 08:23PM 757
F7 A7 Y7 B7 H7 K7 M7 W7 L7 S7 V7 G7 N3 Q0 O0
Which doesn't show any X at all, not even X0 (X is what I want for miles upg right?
If I put in X as the class in the search it only shows me one flight from DFW -> IAH and then IAH -> ANC on CO.
Any ideas on how to check what I'm looking for?
