If arriving by plane, the airport is on the Langgur side of Kei Kecil. Bemos can be hired to take you to Ohoidertawun for Savana Cottages or Ohoililir for Coaster Cottages. Price is between 100,000 and 125,000 rupiah (January 2011) but if arranging for yourself from the airport, the driver will ask for more. Ojeks are much cheaper (25,000 - 40,000) if you can manage your luggage while sitting on the back of a motorbike.
If arriving by ferry, the terminal is on the Tual side of the island. Again, bemos can be hired to take you to the Langgur side but asking price from the ferry terminal will be higher (up to 200,000) so you need to do a little bargaining - should be able to get 125,000, or 150,000 maximum. Ojeks are cheaper, but you may need a little Indonesian to explain where you want to go.
When returning to the airport or ferry terminal, the owner of your accommodation should be able to 'get a friend' with bemo to take you for 100,000 - can be more comfortable than an ojek especially during rainy season.
While staying in Kei Kecil, the best way to get around is by morobike - can be hired for the day - at Savana Cottages it was 50,000 rupiah for the day plus fuel (an extra 10,000) - for a great opportunity to see many sights on the island.
there're only 2 airlines operating the ambon-kei kecil route now.
wings fly on mon, wed, fri & sun, while trigana flies on sun, mon, tues, fri (not too sure about trigana schedule but they don't fly daily). there's no flight on thurs for both airlines. wings is more expensive at the rate of almost 900 000rp at the time when i was there (sept 2007) while trigana costs about 700 000rp.
my advise is not to purchase your tickets from agents but directly from the airlines as agents in kei kecil will quote exceedingly high prices. wings office in kei kecil is in tual near to bmi bank.
flight from ambon to langgur is on every tues, thurs, sat and sun at 2.45p.m.
it is about 600000+ rp.
flight from langgur to ambon is on every mon, wed and fri at 6a.m.
there are about 2 or 3 airlines which fly to kei island from ambon but all depart on the same days.
