What fare class does a HOD upgrade offer book into?
Hi FT AA fam. I'm flying in 2 weeks on a BWI-JFK-MIA r/t, and got an upgrade offer for $160 o/w from a Q fare. My AS FF# is on the PNR. If I purchase the upgrade, will the flight credit as an "I" class fare? or as an "X" fare b/c it's an upgrade? The extra EQM would be nice.
TYIA!
