I had switched from flying WN due to a significant number of delayed flights LAS-SAN. I do drive between San Diego and Las Vegas but not on Sundays as it is a traffic lot leaving Las Vegas on Sunday afternoons.

Interestingly enough I have had a couple of delayed flights LAS-SFO but always made my SFO-SAN connection as invariably the same plane was being used. I now understand it is T-15 (based on responses above) and will not run for a flight. Yes, they accommodated me on the next flight so got to sit a gate at LAX for two hours. If I had known they would leave without me I would have got off the plane in T7, walked to T6 to sit in the AS lounge for a couple of hours and then walked to T8. I am a 1k but this is because I fly internationally and have been increasing my domestic travel with UA during the past year. Yes, one of my friends who i meet up with in LAS and MSY is always trying to convince me to switch to DL but his luggage never goes the same place as him (well to be fair around 25% of the time his luggage travels with him). I had already booked my next SAN-LAS flight and it is through SFO so am anticipating delays but making my (delayed) connections. Also, the Centurion lounge is a nice place to wait in SFO.
