Turkey's primary international gateway by air is Istanbul's Atatürk International Airport. Ankara's Esenboğa Airport handles a comparatively limited selection of international flights, and there are also direct charters to Mediterranean resort hot spots like Antalya in the peak summer and winter seasons. In 2005 customs at Istanbul international airport was rearranged to the effect that one is now required to go through customs and "enter the country" there, rather than first travel to a regional destination and pass customs there. Luggage will generally travel to the final destination without further ado, but on occasion you may have to point it out to be sure it will be transported on. The information given by flight attendants in the incoming flight may not be adequate so until the procedure is changed (it is supposed to be only temporary) it is wise to inquire on Istanbul airport. Since one must pass security again for any inland flight, it is advisable to hurry and not spend too much time in transit. There are also some other regional airports which receive a limited number of flights from abroad, especially from Europe and especially during the high season (Jun-Sep).
Sabiha Gökçen Airport (SAW)
Of special interest to those traveling on low-cost carriers, this airport is situated some 50km east of Istanbul's Taksim Square on the Asian side of Istanbul. Airlines servicing this airport include EasyJet, Germanwings, Condor, THY (Turkish Airlines) and many more. It is interesting to point out that there is the possibility of catching a plane from Emirates' budget carrier Air Arabia to Sharjah (United Arab Emirates) and from there to India for a very competitive price. All those low-cost options though, entail departure and arrival times in the middle of the night.
You can still travel from Europe to Turkey by train, although these days this is more of historical or perhaps even romantic
