I'm travelling to Europe with my girlfriend in the near future. She has had some back problems recently, so I was planning on trying to upgrade her ticket to business (at a minimum on the outbound flight so she can lie flat and not be in too much pain while on the trip). I see that you can use 25,000 AA miles and pay $350 to upgrade, but was curious if there were any better ways to upgrade that I was unaware of. I don't have any status (other than Alaska MVP) with American, so no SWUs or anything like that available. My tickets were booked cash through AA and hers were points through BA. I am just hoping to upgrade at least one of the seats.
