My flight from LAS to SFO later today seems to be delayed for 75 minutes due to ATC issue, which might cause me to miss the connecting SFO-PAE flight. If I missed the flight I will have to stay overnight at SFO. How likely would AS to rebook me (no status) on a LAS-SEA flight and (ideally) compensate me for ground transport from SEA to PAE? If unlikely, what are my options?

Thank you in advance.

Update: agent at LAS check-in was able to move me to LAS-SEA with a Lyft voucher to PAE.
