The landscape may have changed regarding flights to LAS. I was on the phone with SW and they told me that the window would open August 25 to book flights up until April 6 right now it's March 6. Then September 25 for May 6. This may be there new booking policy instead of months ahead of time. Will other carriers do the same I don't know. That being said this makes me think fares will be higher and stay that way. Time will tell. Of course comments are welcome.
