It sounds like in the UG department, you're relatively hosed no matter what do you, so:

(1) What does DL status give you when flying DL as opposed to flying DL with AS status (separate and apart from UGs)?

(2) Does the possibility of flying other AS partners in your mix appeal to you (again, with status perks not being great, but I do think we now get everything but UGs on AA)?

(3) Do you care how valuable your miles or pesos are for redemption?

(4) Does ST status have any benefit for you?

Things to ponder. Obviously, I have not answered your question
