Many airlines fly to Phuket via Bangkok. Thai Airways has one direct flight from Europe with a stop in Bangkok. Malaysia Air flies via Kuala Lumpur, once in a while for acceptable rates. Direct flights from Europe are available in the season by various charter companies. In the arrival hall of International Airport Phuket there are money change counters by several banks. At official rates they change cash and travellers' cheques and accept credit cards by Visa and Mastercard.

From the airport an orange bus for airport staff drives every hour for 80 Baht to the old bus terminal in Phuket City (not in the afternoon).
For Khao Lak (80 km, 75 min.) the only direct transfer is by taxi. In the arrival hall there is a counter labeled "Airport Limousine" where coupons are sold (1800 Baht for 1 to 3 persons). When there is high demand it may take some time before a limousine is available.
Most resorts in Khao Lak offer a transfer service for booked guests for 1200 to 3000 Baht.
