Check the seat map before booking, but if it is a new product it BOOK - it is worth the miles! But... if you can book AA on B77W/refurbished B767 - this product is even better. Avoid BA and old C on AA.
I'm having difficult seeing what the open seat is. I can see the flight but since I don't have the miles in my iberia account yet its not showing me what seats are open. Is there a way to see this without having to transfer all my miles into the iberia account first? The NYC to Spain portion would be on A340-500 the second leg which is only a few hours would be A319.
