Travel by Plane

When you travel to Turkey, keep this in mind: Turkey is big: 1700 km (1056 miles) from east to west if you travel by road, a trip of several days.

But you can fly from Istanbul (west) to Erzurum (east) on Turkish Airlines (TK, THY) in about two hours for a one-way fare of as little as TL79 if you buy your ticket well in advance. Most other TK domestic flights cost between TL69 and TL200.

Because of the way international airfares are structured, it is often far cheaper to purchase your Turkish domestic flight tickets within Turkey rather than in your home country. A good Turkish travel agency can make your flight reservations for you, and get the tickets to you, usually at no charge to you.

You can also buy your tickets right at a Turkish airport, but with Turkish tourism booming, there may be no seats left on the plane. Advance reservations are highly recommended unless you are a very flexible traveler. The farther in advance you buy your ticket, the cheaper it is likely to be.

Onur Air has a fast-growing list of domestic flights with fares as low as TL69 per flight. I've flown them with satisfaction.

Other low-fare Turkish airlines are Atlasjet, IZair, Pegasus Airlines, and Sun Express. EasyJet also flies from the UK to Turkey.

Sun Express, a Turkish-German joint venture, flies from Austria, Germany and Switzerland to Turkey, and within Turkey from Izmir's Adnan Menderes Airport to Adana, Antalya, Diyarbakir, Erzurum, Kayseri (for Cappadocia), Konya, Trabzon and Van.

But be sure to check airport transfer costs as well!

Most long-haul international flights land at Istanbul's Atatürk International Airport. See Major Airports in Turkey and Turkish City Airport Codes.

Turkish Airlines is a competent national airline with good service, a young fleet, worldwide routes and domestic connections to every important Turkish city.
