If this is the case, I'm done with Delta. I have a trip booked with mostly middle seats and just found out they are now selling some of the window and aisle seats.
Welcome to Flyertalk

You cannot transfer points from one FFP to another FFP. This mean that if you are a member of both Korean airline program and Delta Skymiles program and have points (miles) on both of them, you cannot consolidate the 2 programs by transferring all the miles on one of these 2 programs. But you can earn DL points flying Korean (and reverse) and redeem miles with all Skyteam airlines and partners. When you book a ticket, you need to give the FFP on which you want the miles credited.
