Hi, jedimaster1, and a belated welcome!

I can't be of much use in comparing the two programs since I don't fly United much. There are lots that do, though, and I'm sure you'll find no lack of opinions!

I would like to say something about the Delta million miler program, though. Bear in mind that now Delta only counts BASE miles towards qualification. No bonus miles, no dining miles, etc. It is much, much harder getting a million miles on Delta than it used to be, so just keep that in mind when deciding.

Both programs have pros and cons, it's important to remember how they work out in the REAL world, and in your own personal travel situation, that counts.

Good luck!
