San Diego’s airport is three miles from downtown, which is rare for a city this size. Balboa Park and the zoo, the Gaslamp Quarter, La Jolla and Coronado are the first-visit list, the weather is warm and dry most of the year, and Tijuana is right across the border.
The airport’s route map lists a seasonal nonstop between Indianapolis and San Diego, but none of the itineraries Google Flights priced on October 9 for the dates we read was nonstop both ways. The cheapest fares were Frontier, connecting through Denver, at $144 for a week leaving December 8. American through Chicago, Dallas–Fort Worth or Phoenix and Southwest through Denver, Phoenix and other cities started at $217. The lowest round trip we’ve recorded on this route is $144, and before this fall the low was $148, from May 2024.
