Can you fly nonstop from San Diego to Europe?
Yes. San Diego has three nonstop routes to Europe: London Heathrow on British Airways, Amsterdam on KLM, and Munich on Lufthansa. British Airways flies London up to twice a day and added its second daily flight in 2024. KLM launched Amsterdam in May 2025 with a Boeing 787, as Fox 5 San Diego reported. Lufthansa flies Munich, not Frankfurt, which trips up a lot of travelers.
The London flight is the long one, about 10.5 hours eastbound across roughly 5,470 miles. There's no nonstop to Paris, Frankfurt, or Zurich right now. If Europe's on your itinerary, it's smart to settle whether Global Entry is worth it for a faster arrival home, and to know which lounges you can get into before a flight that long.
What other international nonstops does San Diego have?
Beyond Europe, San Diego reaches Asia, Canada, and Mexico without a connection. Japan Airlines flies Tokyo Narita and moves to daily year-round service from August 2026, per Japan Airlines' schedule announcement. Copa added Panama City in June 2025, which opens one-stop access to much of South America. Canada gets four routes. Mexico's beach cities stay busy through the winter.
Destination | Airline(s) | Region |
|---|---|---|
London Heathrow (LHR) | British Airways | Europe |
Amsterdam (AMS) | KLM | Europe |
Munich (MUC) | Lufthansa | Europe |
Tokyo Narita (NRT) | Japan Airlines | Asia |
Panama City (PTY) | Copa Airlines | Central America |
Toronto (YYZ) | Air Canada | Canada |
Vancouver (YVR) | Air Canada | Canada |
Calgary (YYC) | WestJet | Canada |
Montreal (YUL) | Air Canada (seasonal) | Canada |
Los Cabos (SJD) | Alaska, Southwest | Mexico |
Puerto Vallarta (PVR) | Alaska, Southwest (seasonal) | Mexico |
What about flying to Mexico from Tijuana?
Flying to Mexico? Look at Tijuana International (TIJ) before you book out of SAN. It usually wins on price and reaches a lot more of the country. TIJ flies nonstop to more than 30 Mexican cities San Diego doesn't serve, including big hubs like Guadalajara and Mexico City plus smaller stops like Morelia and Aguascalientes. You reach it through the Cross Border Xpress, a ticketed pedestrian bridge on the San Diego side that drops you straight into the TIJ terminal. Buy a CBX ticket, walk across, and you're inside a Mexican airport without driving into the city.
Tijuana makes the most sense for Mexico trips beyond the Cabo and Puerto Vallarta beach runs, where San Diego's own nonstops are already strong. Fares on Mexican carriers like Volaris and VivaAerobus often run well below what you'd pay at SAN. Budget an extra hour or so and roughly $30 each way for the crossing.
One catch on the way home: crossing back into the US requires both your passport and a valid CBX ticket. Forget either and you'll be stuck on the Mexican side.
San Diego runs a global network on a single runway, and it's about to get busier.
What new nonstop routes are launching in 2025 and 2026?
Alaska Airlines is driving most of the growth. The carrier is expanding San Diego service more than 35% in spring 2026 versus a year earlier, according to Times of San Diego, with new nonstops to Tulsa, Dallas-Fort Worth, Oakland, Raleigh-Durham, and Santa Barbara joining 2025 additions like Chicago, Denver, and Phoenix. Southwest is answering with its own new routes for spring 2026, including Santa Rosa, Dallas-Fort Worth, Boston, and Santa Barbara, reported by KPBS.
The new Terminal 1 is behind the timing. Its first phase opened in September 2025, a roughly $3.8 billion rebuild that added gates both airlines wanted. Southwest still carries about a third of SAN's passengers, with Alaska, American, Delta, and United each near 12 to 13% (Flight Global, 2025). Alaska is spending hard to close that gap, and travelers get the routes.
The airport already has its largest schedule ever, with 87 nonstop destinations, the most in its history. Reliability starts to matter more as the gates fill up.

What is San Diego International Airport?
San Diego International Airport (IATA code SAN) is the main commercial airport for San Diego, California. Locals still call it Lindbergh Field. It sits about three miles northwest of downtown on 663 acres beside San Diego Bay (Wikipedia), and it's frequently called the busiest single-runway commercial airport in the United States. The airport words it more carefully, describing itself as one of the busiest single-runway airports in the world and the third-busiest in California. In 2024 it served 25.24 million passengers on that one runway, which is exactly why the Terminal 1 expansion carries so much weight. The airport's official nonstop destination list stays updated as routes change.
