I live in Seattle and this year I will make 1P on UA and MVPG on AS again. I go to NY, SFO, LAS, LAX& BUR, and PHL mostly and the AS schedule is very nice. All nonstops and instant upgrade on most west coast flights. Getting upgraded on a long=haul flight on AS is harder.

UA is nice to handle the international flights and get the *A credit. Their first is nicer and once you make 1P the upgrades are nice. BUT, you always have to connect through somewhere, which doubles your chance of a delay and can mean on avg it could take you twice as long to reach the east coast as a comparable AS flight.

I see a lot of people go the AA route. That makes sense to me, but I haven't done the research myself.

I have been debating whether I should try to qualify on both again next year or try and get 1K on united. still tbd.
