Combine alerts with flexible-date searches and consider minor nearby airports or mid-week departures to increase your chances of snagging cheap economy seats.
Arriving at San Diego (SAN) FAQs
Cheapest Economy Fare (ECONOMY) typically includes a standard seat and may include only a personal item, with additional fees for carry-on bags, checked luggage, seat selection, and inflight amenities.

Yes — in March, spring-break demand can raise prices on popular beach and family destinations, while April’s shoulder-season often yields more cheap economy arrivals. To find lower fares for March and April, search flexible dates, fly mid-week, and set fare alerts to capture price dips.
Arrival times vary by airport: major hubs can take 45–120 minutes for immigration and baggage claim, especially during peak periods. For cheapest economy travelers, pack essentials in a personal item to speed through baggage collection, and check airport arrival tips to minimize wait times.
Many airlines offer paid upgrades at check-in or the gate for available premium seats; however, availability varies by flight and carrier and prices may be higher than pre-purchase upgrades. If an upgrade is important, compare the pre-flight upgrade price to gate offers and consider loyalty status for complimentary or discounted options.

Using nearby city airports or ground transport can unlock better fares and flexible itineraries.
