Thanks for all the advice. I was a high level elite for a decade on NW / CO / then DL but haven't flown much in the last ten years or so. Have about 40k in DL, 15k in UA, and zero in AA right now. Scored a j ticket to SIN on Qatar in the last sale that if booked to AA will give immediate elite status. Another 1000 spend and 4000 miles will get me to the next leveL. Hate having to split the tickets into two separate accounts, but don't think I have much choice. Thanks again for all the advice!
