Although I never took a domestic flight in Costa Rica, this can be another convenient way to travel between different parts of the country, especially if you don't want to deal with the challenges of driving. The planes used for domestic flights in Costa Rica are typically small, with seating for 10–20 passengers, but are considered safe and comfortable. Domestic flights are operated by Sansa to many popular tourist destinations across the country, including Manuel Antonio, Tortuguero, and the Osa Peninsula.

These flights can save you time compared to traveling by bus or car if you're traveling to remote areas. However, for short-distance flights, it might not save you time considering you have to travel to and from the nearest airport, board and disembark, etc. It's important to note that flights can be subject to weather-related delays or cancellations. Also note that not every domestic airport has a direct connecting flight, although you can contact Sansa for private and charter flight options.
