  • Which airlines fly directly from Philadelphia to San Juan?

    There are different companies offering daily flights from Philadelphia to San Juan, including Spirit, United, and jetBlue, but Frontier and American Airlines offer non-stop flights between the two cities as well. Frontier flies out of Terminal 1, but American Airlines operates flights out of Terminals A-East, A-West, B, C, and F, so check your departure information beforehand.

KAYAK’s top tips for finding a cheap flight from Philadelphia to San Juan Luis Munoz Marin Intl Airport

  • Philadelphia International Airport (PHL) has seven different terminals. In order to navigate the rather large airport, there are free shuttle buses running from Terminal F (Gate F-14) to Gate C-16 in Terminal C (which also provides access to Terminals B and D) and Gate A-1 (which provides access to Terminals A-West and A-East).
  • Passengers who want to leave their car at PHL will find parking garages at all the different terminals (A-East, A-West, B, C, D, E, and F). International airlines operate from Terminal A-West, but different domestic airlines fly out of different terminals, so make sure you check your departure information before going to the airport – especially if you’re flying with American Airlines – so you know where exactly to leave your vehicle.
  • Luis Muñoz Marín International Airport (SJU), also known as just San Juan Airport, is located just three miles from the city center. U.S. citizens do not need passports or immunizations to travel in Puerto Rico.
  • If you want to grab a bite after landing at SJU, there are several restaurants throughout Terminals A, B, and C, including Gustos Café, Vienna Snack, and Mango's Village, just to name a few. There are also duty-free shops in these terminals, in case you want to take advantage of the lower prices of products at the airport.
  • If you wish to rent a car at SJU, there are several companies that you can head to, including Alamo and Budget. Onsite rental car companies are based on the first level of the Garage Parking area.
