San Diego Airport is busy enough that generic airport advice is not enough. The useful question is not only when to arrive, but when to leave from your actual starting point. For SAN, that means working backward from your flight time and adding the local details that can change the trip: I-5, Harbor Drive, downtown traffic, cruise traffic and terminal construction patterns, terminal choice, parking or rideshare access, transit schedules, checked bags, TSA PreCheck and the larger buffer often needed for international departures.
Operational details can change, so verify your terminal and travel schedule before departure.

San Diego Airport (SAN) leave time depends on I-5, Harbor Drive, downtown traffic, cruise traffic and terminal construction patterns, the correct terminal or concourse, parking or curbside access, checked bags, TSA PreCheck, airport transfers and whether your flight is domestic or international.
Use about 2 hours before a domestic flight and 3 hours before an international flight as a planning baseline. Add time for parking, rail or terminal transfers, and follow any earlier deadline supplied by your airline.
Yes. Enter your starting location and flight time to estimate the trip for your travel window. The result also includes airport-processing assumptions and the arrival method you select.
At SAN, plan around I-5, Harbor Drive, downtown traffic, cruise traffic and terminal construction patterns, san uses terminals 1 and 2, and terminal construction can affect curb access and walking patterns. A short drive can still require buffer for parking, curb queues, bag drop and temporary construction routing. MTS bus and trolley connections can work through downtown, but transfer and shuttle time need to be included.
