There is a bus service linking the airport to Krabi and Ao Nang. Buses leave 10 to 12 times daily, but the schedule is adjustable depending on demand - buses leave once sufficiently full of passengers. Taxis and motorcycle taxis are generally also available outside the terminal; note that 'limousine taxi' usually just means an air-conditioned taxi. Fares have been standardised and must be pre-paid in the airport.
Car rental is possible at the airport.
Facilities are fairly limited, but the airport provides the basics: souvenir and snack booths, a coffee shop, a restaurant, ATM machines, and a simple money exchanging facility are available.
Parking is available at Krabi Airport.
