The boss is going to India next week and is currently only US flyer. Which program will benefit her the most ? AA or BA? She would use the miles for U.S. domestic redemption. I'm thinking Avios but I never fly Oneworld either. (In fact I didn't even think they were one of our preferred suppliers) Booked as AA code share on BA metal, business class. PHX-x-ORD-x-LHR-MAA/DEL-x-LHR- PHX. Does anyone have an opinion?
