Is it possible at all to do a cash upgrade on an Avios award ticket booked through BA
Booked two EL award tickets end of June 2019 for economy, JFK-SNN. Is it possible to offer cash to upgrade? I don't think they'll open more business availability for awards which I know I could upgrade using more Avios but I'm not sure.
I booked by transferring MR to BA and then booking over the phone to get cheaper taxes/fees.
