Airlines on this route
Alaska Airlines flies this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another.

See our airline guides for exactly what each carrier charges — then send an enquiry and we'll confirm the all-in price for your dates.
Leaving from San Diego (SAN)

Our San Diego airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.

When to book
For a trip of 2,672 miles, booking 4–8 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
