Since its flyertalk, naturally I'd fly but either way if you have a car once you get to ELP, I really like Mesilla NM around 40 miles away as it has a time warp old town area:

Back to flying, If my work is buying I go from SGF on UA for the miles but if I was paying I'd compare the $ for Southwest from TUL.
