Worth noting that at least for BUR-SFO there has been a *lot* of mileage ticket avail for 5K miles each way on UA a few days out. I assume this is in response to F9.
Nice product at that price! I plan to move all my CC spend back over to UA. to make more miles.

As with a lot of other, soon to be, refugees from Southwest I really wish someone would properly focus on the intra California commuter market. F9 is cheap and reliable but poor density. Anything involving SFO is iffy in the Winter months.
