Flying into Burbank vs. LAX - worth the hassle of changing planes in PHX?
Not to throw a wrench into the mix but keep in mind that going to BUR involves a stop/connection. You take an increased chance of misconnecting/delays due to wx/mx/etc versus taking a n/s to LAX. Taking into account WN's recent on-time woes, just beware you could be in for more than you bargained.
