I just noticed TUS-LAX went from $70 to $96 and PHX-LAX went from $70 to $98. I haven't seen TUS-LAX cheaper than PHX-LAX in a while.
If you gotta go last minute, this is the new reality I suppose. I guess I need to start booking more of my flights 2-3 months out and (hopefully) rebooking the lower fares.
