I'd still rate Delta above AA and UA in terms of reliability, but to say 2022 Delta is the same as 2019 Delta, let's not kid ourselves.
And as someone else also mentioned, the lack of flights through DTW and MSP is quite pathetic. I would understand if they kept "pandemic" schedule for the most part as many people left/took an early out/retired, but these schedules are even worse than 2021, and even then they can barely cope. They did not have a mass exodus of people suddenly leave in 2021 so not sure what their issue is.
OK enough Delta bashing from me, none of the other airlines are any better so methinks this has to do with horrible HR departments that they never gutted.
