My wife and I are traveling to Ireland in July for our 10 year anniversary. We booked our tickets with Delta to fly IAD-CDG-DUB on July 21, 2016. When I look at seat inventory on AirFrance on the upper deck there is plenty of inventory in economy but does not show on Delta. I have tried calling both Delta and AirFrance to try and purchase those seats, but they both state they are unable to seat those seats as available. AirFrance only stated that I can call in at 48 prior to the flight and book them. I am pretty sure at this time all the seats will be taken. Is there anything I can do? My wife would like to be on the upper deck on the side of the plane with a window if at all possible.
