I used my last SkyPesos to fly a family member cross-country this week, starting Friday morning. The first segment is EWR-MSP. I was able to get her a seat assignment when I booked the ticket with the Pesos about five weeks ago (way in the back of the bus). However, periodically coming back to see if I can get her an aisle seat, the last several days have shown the pop-up: However, I can still see seat maps for the other segments (in fact, was able to change seats on a different segment). Is this an oversold situation I'm seeing? She DOES have this seat, right? Details: - Can still see seat number (the one I assigned her) in the itinerary section for this segment. - Economy, N class booking. - I, nor the passenger, have any Delta status whatsoever. - Flight from EWR to MSP is Friday morning.
