I'm currently Plat on AA and flew 90,000 miles last yr. DL is one of my backups and I flew 20,000 on them last year. Given the distribution of my clients I should easily do 25,000 DL miles this year. However, 50,000 miles would be a stretch as I plan to keep AA as my primary.

Am I better off requesting match to DL Silver or Gold? I know that Gold is higher status, but if I get matched to Silver, and then fly 25K miles, could I do a match again at some time in the future (in case I decide to dump AA for DL)?
