Costa Rica has two domestic airlines (see schedules and rates NatureAir and SANSA) that operate from two different airports near San José. The direct flights shown on the route map below last between 15 minutes and an hour, and cost between $40 and $160 each way (plus airport charges, taxes, and fuel surcharge totaling $8-18).
International flights in jet aircraft can land at SJO (Juan Santamaría International Airport outside San José) and LIR (Liberia International Airport in Guancaste). Occasionally private jets land in Limón but there is no scheduled international commercial jet service. The other airports range from literally grass landing strips in the jungle at Sirena near Carate on the Osa Peninsula to a couple of small buildings and a paved runway in places like Manuel Antonio, Tortuguero and Golfito.
