I'm mainly an AA flyer, but I primarily fly WN within California. I take somewhat frequent trips from SFO to LAX and occasionally to other cities. In a given year, I comfortably make Platinum but rarely get close to EXP. I am debating whether or not it would be worthwhile to move my SFO-LAX flights from WN to AA.

I have had somewhat sketchy on-time performance from both airlines when flying out of SoCal but on the whole WN has been worse. Lately, almost every single one of my WN flights has been delayed and I am fed up.

Pros for AA:
T2 at SFO is much nicer.
Admiral's club access.
Additional miles into my main program, comparable or better than those from a WGA fare on WN.
I actually get a seat assignment and get to board early regardless of fare paid.

Pros for WN:
More flights.
For some reason I can often get away with buying a BS fare. I can always buy up to BS when I feel like getting on an earlier flight. I can't get away with buying AA fares that book into first, however, even if the price is the same.

Thoughts?
