Booking C with AA miles and then upgrading to F
After speaking with a bunch of people at the first ever LY mini-DO, the idea of opening a couple of AA credit cards to get 120K miles and book 2 r/t tickets, TLV-BKK on LY in C intrigued me.
Question though: I'm aware you can't book F with AA miles. However, if I book C, is there a way of upgrading to F? Do they ever even have F service on the BKK flights?
