Trying to figure out if I should transfer Amex to Avios, since once it's transfered, I can't transfer it back.
Here is my flight information:
On the DFW-LHR I see:
F5 A4 J9 C9 D9 R5 W9 E9 T9 Y9 B9 H9 K9 M9 L9 V9 O8 G5
On the LHR-DFW I see:
F8 A6 J9 C9 D9 W9 E9 T9 Y9 B9 H9 K9 M9 L9 V9 S9 N9 Q9 O9 G9
How to tell if upgrade seats are available? What seating class are CW upgrade available seats? Is it U?
Thanks
