Hello! I have a Delta Main Basic award ticket coming up and noticed a schedule change. Chatting with the Delta rep on delta.com and was told the alternative flight I want is “sold out”. I see Delta is still selling award ticket for the flight I want in the Main Classic, but not in Main Basic.

I thought in the past, if there’s a schedule change as long as there’s a seat in the Main cabin, it’s fair game. Is this something new?
