Just Milesaaver,

Have you thought about flying AA direct to Miami, as BA silver you should be able to get Exit row assigned according to others on the AA board. On the 777 it is a fairly good seat. Plus book before May 31st and travel before November 15th and get double miles into a AA account. Near enough a free European flight. I paid 290 quid for a MIA flight earlier this week for November.

Of course if you have an expiring voucher, ignore.
