US has significantly cut down on their number of flights between LAX and PHX. In the HP and just after the merger days I think it was between 8 and 10 flights a day including a ~9:30 PM flight and a ~7 PM flight. Sadly, UA has cut down on their number of flights on this route too from their peak of 6 in the mid-2000s. WN seems to be the way to go for frequency
