FYI to US folks. The AAngles at the AC in SFO are some of the best in the system. They go out of their way to accommodate folks in IRPOS, flight cancels etc. Very proactive.
On at least two occasions they proactively rebooked me on UA PS to JFK when my AA flight was cancelled or significantly delayed and called me well before my scheduled flight to tell me to just check in with UA and had the same J class of service and even F on one occasion back when they still had F. Helps i'm sure that i was EXP but great staff at SFO.
