I fly out of CVG every week on DL. In my opinion, DL has maintained their flight level at a minimum or even increased it. The passenger level is back above pre covid. There are still some DL directs that I wish they would bring back(DFW, BWI, SFO, PHL, AUS) but they options are still good enough for me. DAY has REALLY reduced their DL presence. Only ATL and LGA(1x day)
