I will probably have about 30k-40k a year in spend. Covid has been a boon for me - I got 3k PQP's from UA for being 1k last year. I have done about 27k so far this year. It seems like that should get me something with one of the airlines, but honestly there are just no guarantees. I don't think AA is necessarily better that UA or DL, but I do think that all the airlines are good in certain areas. I see some fantastic F fares over to asia on AA that I just do not see from either DL or UA.
I tried to status match to AA in 2020 but the flights got smoked by covid so I lost it. I think I would be starting over from scratch as AA probably wont let me do it again.
