Quick question. I just had an aircraft substitution on my upcoming VFA-(GBE)-ADD flight, going from a 737 to 787. Yay! When I go onto the app to select seats, there are no problems, but when I go back to look at the reservation, it still says "no seat selected". Going back to the "Select Seats" button, it shows the seats that I had previously selected as occupied, but does not show them as "my" seats. Do I need to call in to confirm? Or is it just a bug with the app?
