"Self-upgrading" at seat selection in Delta App
I was looking at seat selection for upcoming domestic flight (flight is in a couple of days, upgrade requested but not cleared yet) and noticed that I can select 1st class seat without usual upcharge.
I went ahead and changed seat to 1st class. The booking code changed from L to OU.
Was it a glitch or I just happened to check seats when upgrade was already cleared but not processed yet?
Have not received any usual upgrade notifications from Delta.
