This is probably a dumb question, but is there any way to earn Alaska miles on AA metal by booking through BA? I don't need any more AA miles this year--not going to make the next tier by spend, so more miles is pointless. I could use the Alaska miles to keep MVP. So I looked at BA flights for my upcoming international trip, but there's nothing that really works expect of course the AA flights they also return in their search results. I am guessing I cannot do this but can't find it explicitly stated anywhere.
