While I like to redeem miles and points for first and business class on long international flights, Southwest is by far my preferred airline for domestic flights.  However, Southwest offers international flights to many popular travel destinations in Mexico, Costa Rica and the Caribbean so it is also a great option for shorter international flights to warm weather destinations.  Southwest’s international flight network is even more motivation to earn the Southwest companion pass.

List of All Southwest International Flight Destinations

Following is the list of all Southwest international flight destinations:

  • Aruba (AUA)
  • Belize City, Belize (BZE)
  • Cancun, Mexico (CUN)
  • Cabo San Lucas/Los Cabos, Mexico (SJD)
  • Cozumel, Quintana Roo, Mexico (CZM)
  • Grand Cayman (GCM)
  • Havana, Cuba (HAV)
  • Liberia, Costa Rica (LIR)
  • Montego Bay, Jamaica (MBJ)
  • Nassau, Bahamas (NAS)
  • Providenciales, Turks and Caicos (PLS)
  • Puerto Vallarta, Mexico (PVR)
  • Punta Cana, Dominican Republic (PUJ)
  • San José, Costa Rica (SJO)
  • San Juan, Puerto Rico (SJU)

Note: Even though Puerto Rico is a US territory and is considered a domestic flight from the US, it has been included because some Americans think it is an international flight.

Below is the list of all Southwest international flight destinations by country (along with a list of U.S. cities that offer non stop service). You can also view all the Southwest international destinations on www.southwest.com by using the Interactive Southwest Route Map here.

I have visited a few of these places (Cuba, Belize, Costa Rica, Grand Cayman, Cabo, and Puerto Vallarta) before flying Southwest was an option (Southwest first started offering international flights in 2014 and has been rapidly adding destinations since then). In the future, I would most likely fly Southwest if I were to return to these places or travel to another Caribbean destination on their route map.
