I have 4 SWUs that will expire at the end of February. In early March I am traveling to MIA with a friend. Needless to say, it would not be particularly nice to upg and leave him back in Y. Otherwise, I would be forced to burn through the stickers that I have remaining from my previous PLT days.
So I called the EXP desk this morning to see if I could apply those four SWUs post 2/28. While typically the SWUs must be used for flight by 2/28, the EXP agent was able to make an exception and use them for a March flight.
