San Juan is a U.S. territory, so flying to it counts as a domestic trip. Old San Juan holds the city walls and the two forts, El Morro and San Cristóbal, and the hotels line Condado and Ocean Park beaches to the east. The airport is in Carolina, in the Isla Verde resort district, a few miles east of the city.
The airport’s route map lists a seasonal nonstop between Indianapolis and San Juan, but none of the itineraries Google Flights priced on October 9 and October 16 for the dates we read was nonstop. The cheapest fares were Frontier, connecting through Fort Lauderdale, Orlando or Atlanta, and the lowest, $145 for three days leaving November 7, read on October 16, connects in Fort Lauderdale the same afternoon on the way out and leaves San Juan at 3:55 AM coming home.

Delta, American and Southwest started at $426 on the dates we read. The $145 ties the lowest round trip this site has ever recorded on the route, from April 2024.
