There are two domestic airlines: SANSA and Travelair. Demand for seats is high, so try to book as far in advance as possible. San José is the main transport hub and there are buses from here to most parts of the country. Taxis are considered a viable form of public transport for long journeys, and can be hired by the day, half-day or hour. Cars and motorbikes can also be rented in San José. The railway network in Costa Rica was severely damaged during the 1991 earthquake and is unlikely to reopen.
