You're a little low, but not too far off. PHX-LAS: $131; PHX-ABQ: $134. That's what it shows on southwest.com for tomorrow's flights.
I do a lot of last minute WN flights, and they don't price gouge ever. I believe I read somewhere in their literature that they will never do last minute price hikes. They reach their highest price about 7 days before the flight, and they will not raise it anymore. Their pricing is probably the most fair in the industry. Short flights cost less than long flights, virtually anywhere in the US. Also, almost all of their tickets are cash refundable (I think only the fun fares arent), and if you change a flight, they charge you $5 bucks yes $5 bucks not $100, or whatever the US Airways Fu*k Fee is... (that's what I paid last year, it may have changed). They give refunds if you ask before, or after the flight, even if you forget to cancel... They are in it for the long haul, they really don't abuse their customers...
Ok, so one of the days when I said I'd never fly US Airways again... This is a true story. I had a flight cancelled from BOS to AVP. I had to connect in PHL. Last minute in BOS, they had a seat for me on another flight, I had to run to the gate. At the gate, they never gave me my connecting boarding pass when they changed my flight. I paid no attention to it. I got on the plane. When I got to PHL, I didnt have a boarding pass for my AVP flight. I went to the "Customer Services" desk. The lady honestly argued with me for 20 minutes to the point where I just lost it. She kept telling me that I never had a connection to AVP and my original reservation was BOS to PHL and I'd have to pay $1900 to take my 20 minute flight to AVP. I was like, think about what you are saying... Why would I choose PHL as my final destination when I started at AVP? I really started to get nasty and I demanded the supervisor. About 10 minutes later, someone came over, punched a few buttons and said, "Yeah look here, here's his original reservation".
Well needless to say, I got home. The letter I wrote to "the sandcastle" as you guys call it - got me a $500 credit, but honestly, I am one of the most calm and patient people you'll ever meet, and for them to put me through that was insane... THAT is an example of someting that would never happen at WN.
