This site is great. I have always had the concept of the mileage run in my head and had figured the values of miles and such, but this is awesome.
Ok, I've flown DL mostly through my childhood, currently I've got about 10000 MQMs for the year. With UA I have only 1000 MQMs. I have read mixed reviews about DL's medallion program and was wondering if anyone had some insight. Either way, I will probably go for only 1P this year (SM or Premiere). Of course, it would be easier to go for the DL as I am about half way there (and if I upgrade my regular AMEX, I'll get 5000 MQMs for $80). I was thinking about getting the SM on DL and then requesting a comp from UA (although I'm not positive they will comp the lowest status on DL). I do a fair amount of cross-country here in the US to LAX, but love to travel abroad also. Any tips or thoughts would be appreciated.
Also, I currently reside in Nashville (closer to more DL), but will move to Los Angeles in September (closer to more UA). So, in closing, if anyone could have some recommendations while comparing the benefits of each program, I would greatly appreciate it.

Thank You and God Bless

P.S. Or could I try for the AA elite challenge?
