Same thing I was going to say, summer travel to all the national parks ends after labor day, and it's not ski season yet. Plus throw in all the extra connectivity in LAX and SEA to some smaller cities in the West that can handle connection traffic vs flowing everyone though SLC as would have been necessary 4-5 years ago.
