I am 1P and my wife is 2P - we have an upcoming trip BWISEA (via DEN) - it is a through/direct flight/same plane - same flight number and appears as a 1 stop in our itineraries.

We would need to use a total of 10 e500s to both upgrade the whole way there. Collectively, between our accounts we have 11 e500s (I have 7, my wife 4). Should we be able to upgrade? We are traveling on the same PNR. Can I transfer my e500s to wife or she to me? Because now we can't do it on .bomb but maybe we could call or just hope for the best at the airport. Anyone have any experience with this? Thanks.
