8190 is normally part of the air canada code share block.
Got it. Looks like UA sub'd in another aircraft for use to LAS. The delayed aircraft from TPA is heading to SAN.
That said, FR24 clearly says 8190 - see screenshot. Searchable on Flightaware as well. UA does not normally do these for replacement flight numbers...
I am on the flight right behind the mystery flight
