I may or may not have mentioned this above or in another thread, but I believe this is an abuse of the joint venture's anti-trust immunity. Presumably AA gets half of that "surcharge" for effectively forcing you over to BA because they no longer feel like operating that flight (how convenient for them). It's infuriating to think that AA can get away with this. I'd definitely complain to the DOT and maybe even the DOJ just for good measure...
