One-Way Flights to San Diego

San Diego International (SAN) is a single-terminal airport right next to downtown — one of the most convenient airport locations in the US. You can be at the beach 20 minutes after landing. Southwest and Alaska Airlines dominate the budget market at SAN. Southwest runs heavy West Coast and Texas routes with free bags. Alaska has strong fares from the Pacific Northwest, Bay Area, and their hub cities. Spirit flies into SAN from select cities with the lowest base fares. Here's the move most people miss: the Cross Border Xpress (CBX). It's a pedestrian bridge connecting San Diego to Tijuana airport (TIJ). Mexican carriers like Volaris and VivaAerobus fly from TIJ to US cities and Mexican destinations at a fraction of US carrier prices. If you're heading to Mexico or even some US cities, crossing the border to fly can save serious money. CBX costs about $16 to cross. SAN has limited gates, which means fewer budget carrier routes than LAX. If you're flexible, compare SAN fares with LAX (2 hours north) and sometimes Burbank — the drive might be worth a $50+ savings. Cheapest months: September, October, January, and February. Summer is peak season with tourists and convention traffic driving prices up. Comic-Con week (usually late July) is the most expensive week of the year. Midweek flights save $20-30 vs weekends.
