2 for 2 this year, LAX-JFK on 2/15 and the return on the 2/15 (Monday).

Query: i got an email this morning that my return flight has been upgraded, but there’s no seat assignment, which hasn’t happened to me before. The two aisle seats that were available last night are gone, so I’m hoping that I was assigned one of them, even though in the reservation it says to select my seat. I”m thinking of leaving well enough alone for a few hours to see if an assignment shows up, since only windows are left from which to choose in J. Or should I call the EXP desk?
