I'll dig on the other plane in a little bit
Yes, but all of the pictures have a timestamp within minutes of each other, while one/two are San Jose and the other is in China, so they weren't taken right then. Someone noted that they were screenshots of the pictures on Q's phone.
Every one of those is an A320 rather than an A321, and has been for the past few weeks at least (looking on FlightAware), so something else is going on with it.
Only the A321 has the prism tail, so it has to be that.
Attached pic is interesting however. Flight cancelled about 12 hours after Q posted that.
Also looks like it was delayed for about 4 hours before they decided to cancel it, since normal flight leaves around 6:30 PDT and that day's says 10:30
