There was a United Boeing 767-300ER, N646UA, at SAN today, 6-23-2013. Flew down from SFO as UA364, departed for IAD as UA554.
No clue why there was this flight today.
It was a 3-class 767, so it only has a few more seats than an sUA 757.
It actually flew into SAN as UAL364 from SFO and had previously operated EWR-SFO as UAL996. Before that it ferried ORD-EWR as UAL6861 on Saturday night. The aircraft had been sitting at ORD since the 19th
Thanks ddrisque, I got an alert on my phone for this flight but I never got to see it since I’m out of town. Hopefully someone got a video or photo.
