Top tips for finding a cheap flight to San Diego (SAN)

Buy plane tickets in the Goldilocks Window

Although we know that shockingly great deals on airfare can pop up at any time, we also know from experience that there’s a sweet spot before any trip when the cost of a flight is typically at its cheapest. We call this the Goldilocks Window. It’s 1-3 months before a domestic flight and 2-8 months before an international one.

There are caveats here, however. If you’ll be traveling during peak season or over a holiday, or your travel dates are set in stone and can’t be adjusted, we recommend adding a few months to the timetable. Folks wanting to fly home to see the family at Christmas, for instance, should be booking flights in about July. Last-minute bargain fares don’t happen very often, either—on the contrary, airlines tend to raise prices at the 21, 14, and 7-day points before a flight. Try to book your flights before then if possible.

Consider flying from other airports

Most travelers who live in the New York City area or in DC are used to looking at multiple departure airport options for their flights simply because there are a few major airports close to home. But even if you only have one major airport nearby, there are still circumstances in which you’d save money on a trip by flying out of an airport farther away from where you live.

Let’s say, for instance, that you live in the Detroit area and you’re looking for cheap flights to San Diego. You might get discouraged by nonstop flights that hover around $400 and either bite the bullet or vacation somewhere else. But if you widen the net a bit, you might find a nonstop flight from Chicago to San Diego for $225 roundtrip, which saves you a nice bit of cash. Even if you add on the cost of a train ticket ($40 one way) to get from Detroit to Chicago, or you feel like driving the 4.5 hours, you’re still coming out ahead.

Plan trips when flights are cheaper

Instead of choosing your travel dates first and looking at airfare second, try starting with the price of airline tickets first and let the cheapest fares determine your travel dates. Being flexible like this with your travel plans and avoiding the high tourist season are two of the best ways to save money on flights as well as hotels.

Of course, a peak season like summer is popular for a reason—not only does it usually mean nice weather, but it’s also when schools are on break. If you can’t be flexible with your travel dates and summer is your only time off, there are still a couple of things you can do to save a little bit on airfare. Look at fares in the first two weeks of June and the last two weeks of August, when flights tend to be a little cheaper. And avoid flying on what are typically the most expensive days (Fridays and Sundays), targeting the least expensive days instead (Tuesdays, Wednesdays, and Saturdays).

Set airfare email alerts

Very few people have the time (or the inclination) to spend hours each day looking for deals on airfare and tracking price fluctuations over weeks or months. Thankfully, there’s an easier way to stay on top of ever-changing fare costs: signing up for email alerts for the itinerary you’re looking at. Once you’re signed up, you’ll get an email notification when the fare drops into the price range you want, so you can buy with confidence. Just note that if your travel plans are flexible, you’ll need to set up an alert for multiple itineraries or use a service like Going that alerts you to fare drops to any destination from your home airport.

Frequently asked questions about flying to San Diego (SAN)

What is the airport code for San Diego International Airport?

The airport code for San Diego International Airport is SAN.

When is high season in San Diego?

Despite the fact that San Diego’s weather is sunny almost all year long, the summer months (especially July-August) are still peak season. Airfare and hotel room rates can be significantly higher in summer than other times of the year, particularly around San Diego’s biggest annual event: Comic-Con, which occurs in July.

When is the best time to visit San Diego?

The months on either end of summer are considered by many to be the best times to visit. March-May (spring) is less crowded, and less expensive, and temperatures only reach the high 60sF most of the time. September-November (fall) is another excellent time to be in San Diego. September weather is usually still pretty warm, but by October, temperatures and crowds drop to a more pleasant level.

Does San Diego International Airport have its own on-site hotel?

What lounges are available at San Diego International Airport?

There are two terminals at San Diego’s airport, but only one has lounges—Terminal 2.

What are the rules for traveling with pets to San Diego International Airport?

The California Department of Food and Agriculture sets the regulations around bringing animals into the state, and it varies depending on the kind of animal you’re traveling with. Unlike some states, for example, California doesn’t require dogs or cats to have a Certificate of Veterinary Inspection (CVI). You must have proof of current rabies vaccination, and the animal must be deemed “healthy.” For more details and information on other types of animals, check the California Department of Food and Agriculture website, and be sure to also check with your airline for their rules for flying with an animal.

Within San Diego International Airport itself, there are seven pet relief areas located both inside and outside security. Five are in Terminal 2, and the remaining two are in the corridor linking Terminal 1 and Terminal 2. Terminal 1 proper doesn’t have any pet relief areas.
