Alaska Airlines Flights from San Jose to San Diego

Alaska Airlines on this route

Alaska Airlines serves SJC–SAN through its hub network, usually with one connection. The nonstop flight time is about 1h 35m.

Fare classes available: Saver, Main, Premium Class, First Class. No change fees on Main and First fares; fare difference applies.

The lowest one-way fare we have on record for this route is $155 on Alaska, and $251 round-trip. Fares like that usually show up on off-peak days and for travel booked a few weeks out; an agent can check whether a similar fare is available for your dates.

Because Delta Air Lines treats San Diego as a hub, this pairing tends to have frequent departures throughout the day. American Airlines, Southwest Airlines, and Alaska Airlines also compete here, which keeps fares in check.

The 417 miles between San Jose and San Diego works out to about 1h 35m in the air, the range where nonstops are common on busy days and connections through a hub fill in the rest. Ask the agent to compare both; the one-stop is sometimes cheaper by a wide margin.

When to fly

West Coast and Mountain departures spike over summer holidays and the December break; January (after New Year), late April, May, and September are usually the cheapest windows.

On this specific route our fare history shows October as the cheapest month and September as the most expensive, a spread of $164 between the two.

Tuesday, Wednesday, and Saturday departures are usually the cheapest days on domestic routes; Friday and Sunday are the most expensive. Early-morning and late-evening flights are often priced below the midday departures.

For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
