They might pay 5k per ticket though.
Also, AS may be blaming boa for pr purposes - perhaps with bofa's approval (perhaps due to pressure).
Or perhaps bofa is demanding refunds from AS, and is getting AS to do the dirty work, but why would AS take the blame if they can just make a deal with any other bank?
Otoh, Why would AS care about the annual fee, unless that's just a bs excuse to get out of paying for 5k tickets.
