I'm looking at Southwest to fly to John Wayne Airport (SNA) from Portland and I'm surprised that they are very expensive and take twice as long (because of having 1 stop) as their non-stop competitors like Alaska, JetBlue (LGB instead of SNA), etc.
On the other hand, I'm looking at Southwest because they have a lot of flights, they let me check 2 bags for free, and I can cancel the flight without penalty.
