Apologies in advance for this n00b question...
As a 2P this year, I can select E+ seats at the time of booking. Since this benefit goes away next year, I'm thinking of crediting subsequent flights this year to another *A program (probably Asiana or Aegean). I've already qualified for 2P next year and unlikely to make 1P; but might make it to *A Gold on Asiana or Aegean next year.

My question is, now do I keep an E+ seat but credit the flight to another *A program?
