My bet is on ONT to start...maybe OAK too, although I thought AS already serves Hawaii from there, but maybe I'm wrong. I think LAS is out of range for the 737, but again, too lazy this afternoon to look up the specs so I may be wrong on that too.

While the "Southwest Effect" is known, their fares are quite often far more expensive than legacy competitors so I don't expect to see any bargains, especially after buying up to priority boarding to avoid 5 hours in middle-seat hell.

Personally I've never flown them in my life, but if I don't need the UA PQM and they are flying from ONT for a price similar to or a small premium over what I would pay from LAX, then I'll give them a shot. I can pack my own food, buy my own beverages inside the terminal, and factor in the cost of priority boarding as a given for the final ticket cost, so why not?
