I live in DFW and fly to SEA almost monthly for work. I never fly anywhere else for work. I'd like to keep my miles in the best place to get status and take my wife somewhere nice one day.

I love flying AS and try to stay with them when I fly for work over AA but I do often end up on AA due to them having more flights on my route.

This year I put all my miles on AA regardless of which airlines I ended up taking and just got gold status. But I'm thinking about putting all my miles on AS for this next year and go for mvp.

So what would you do if you were me?
