Turkey's primary international gateway by air is Istanbul's Ataturk 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.
If you intend to travel to Eastern or South-Eastern Anatolia (colloquially known as Turkish Kurdistan), stay ahead of the news. Although it offers many beautiful sights such as the ruins of Antioch, the situation is far from secure due to ethnic strife and protests, sometimes resulting in violence. The region is far from a war zone, but take precaution when visiting this volatile place.
 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. Very interesting is the possibility of catching a plane from Emirate's 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.
From Istanbul International airport, you can catch the light rail, which will take you directly to the Otogar (bus station) or to numerous stops within Istanbul (Aksaray is the last stop, near Sultanahmed where most of the famous tourist sites are). It is possible to be at the Otogar within less than one hour after landing. Another way of getting to downtown Istanbul is by bus, either on Havaş coaches (special airport shuttle leaving every 30min night and day) to Taksim, Etiler, Kozyatağı (Asian side) or on public buses (Line 96T) to Taksim. Public bus and the light rail costs 1.30 YTL, Havaş about 9 YTL. Taxi is about 20 YTL (2007). Travel times depend a lot on traffic, and Istanbul is heavily congested!
From SAW, Havaş coaches depart regularly to Levent, Taksim, and Kozyatağı for about 7-10 YTL. If you arrive in the middle of the night, you can move to the departure hall after passing customs and rest on very comfortable seats — you will even find coin-operated Japanese massage chairs. Then, at about 4:00 AM (but better ask to be sure) the first Havaş bus will take you to town. The Havaş bus schedule is sometimes linked to the arrival/departure times of planes. Check the company website. There is also a public bus (line E-10) which operates 24 hours a day (once every hour between 00:00 and 06:00, more frequent in the rest of the day) between Sabiha Gökçen Airport and Kadıköy, the main centre of the city in Asian side. It costs about 3.00 YTL.
