What’s New in Guanacaste Flight Routes for 2025 

2025 is shaping up to be a game-changer for direct flights to Guanacaste, and the airlines are stepping up to meet demand. Nonstop routes are getting more frequent, and new ones are being added, especially to accommodate peak travel periods.  

Let’s break down what you can expect for the year ahead. 

Seasonal Flight Increases 

Airlines are ramping up their game, especially during peak tourist seasons in Costa Rica. Thanks to United and Delta, more flights from cities like Boston and San Francisco will be expected in December. Southwest’s adding more flights from Denver in November, too.  

Just know these schedules can change depending on demand, so check in with the airlines before you hit book.  

Established U.S. Hub Connectivity 

If you’re coming from major U.S. cities, you’re in luck. Flights from Dallas/Fort Worth (DFW), Miami (MIA), Houston (IAH), and Denver (DEN) are sticking around with daily nonstop options, courtesy of American Airlines and United Airlines. Northeastern cities like New York (JFK) and Newark (EWR) are in on it too, with JetBlue and United offering daily and seasonal flights year-round. 

Growing Canadian Travel 

Canadian travelers, it’s your time to shine. Toronto (YYZ) is getting daily nonstop service from Air Canada and WestJet. Montreal (YUL) and Calgary (YYC) are jumping in with more flights starting in November, giving Canadian snowbirds the perfect escape route from the cold. 

Expansion from Regional U.S. Airports 

It’s not just the big cities getting the nonstop treatment. Southwest is adding flights from Baltimore (BWI) on Saturdays. Houston’s Hobby Airport (HOU) will also see daily seasonal flights starting in November. This makes it much easier for regional flyers to get to Guanacaste without connecting through a major airport. 

New Routes to Watch 

2025 brings some fresh routes. United Airlines is starting nonstop flights from Boston (BOS), San Francisco (SFO), and Seattle (SEA) on Saturdays starting in January. These additions are huge for those on the West Coast and in the Northeast. With these new connections, Guanacaste is becoming even more accessible from all corners of the U.S.
