I have a reservation using Jetblue points booked with my Trueblue not AA. Manage Trips and then "Update Traveler Details" at the bottom of the page does not give me an option to change FF from JB to AA. It's deactivated.
It is somewhat strange in the first place for JB to even allow points redemtion with AA number but I just made another reservation with points as AA EP.
I see 1 free check bag probably from my JB credit card.
Hopefully 10% points back as a cc holder does come in after trip, too.
LIttle too good to be true using JB points, travel bank and cc benefits as well as AA EP all at the same time, but no complaints.
