Fortunately enough for Icmeler the nearest international airport Dalaman (IATA: DLM) is about 100 km. Overall the airport of Dalaman is a modern terminal as its international part was built only in 2006. With 12 boarding gates Dalaman International airport sees an average of 3,5 million people every year. More passenger traffic is seen in the season May to November. Off season there are daily flights from Istanbul, Ankara and weekly charters from the United Kingdom as well as some other European countries. You could always reach Dalaman airport via Istanbul on an international flight or find a domestic flight from Istanbul to Dalaman. As international flights require to check in 2 hours before departure time this brings you to the airport earlier. Many travellers continue to report on high prices for food and drink at the international terminal in Dalaman airport. However, in-flight drinks and meals are of no different, unless you pre-ordered it before. You could perhaps spend the left-over Turkish lira at the airport instead.
Milas – Bodrum airport (IATA: BJV) is your second choice although it is further away from Icmeler resort. Its modern international terminal was completed back in 2000. From time to time Bodrum airport has better options on charter and domestic flights in terms of times or prices.
The international airport in Rhodes – Diagoras airport (IATA: RHO). Yes, this is in Greece, but if you look on the map you will realize just how close the island of Rhodes is to Icmeler and Marmaris. The distance by sea is only about 50 km. With daily connections from Rhodes to Marmaris you could catch a ferry or a fast cat from May to November. Less frequent schedules are available in the ‘off-season’ period. For more information about this alternative route and current availability info and schedules visit https://www.blueguide.com
Both Dalaman and Bodrum airports are located out of the city which limits your options for transportation to a taxi, or a private transfer, or a bus transfer for package holidays. Among the three options private transfers are perhaps the best due to convenience and ease of use. You could book a private transfer with a local company that arranges a private car or a minibus with a driver, according to the size of your arriving group. Nowadays most transfer companies use fully air-conditioned cars, like Ford, Renault or Mercedes vans and professional drivers who can speak some English. Unlike transfer companies some taxis continue to use older cars and sometimes without air-conditioning… Also transfer companies are now required to have additional licenses to carry passengers and have to meet basic quality and safety standards, as they are checked by tourism authorities as well as airport police. However, the cost of a private transfer is usually the same if not less than a taxi ride. You can check further information about the prices and availability on http://www.transferturkey.com/
The only form of public transportation that is available from Dalaman and Bodrum airports is the buses run by HAVAS, that serve domestic flights only. It is not an easy thing for a local, let alone a foreigner to catch a Havas bus, as they run without a proper schedule. However, if you do catch their buses it is perhaps your lucky day, as the cost is very cheap and ideal for one or two passengers.
Happy & safe travels!
