TURKISH AIRLINES 2011 Frequency is fine. They seem to offer exactly 3 daily flights all year round. Problem with them is the price. They won't sell a return ticket cheaper than around 250 euro. Second problem is when you try to book only a few weeks in advance. Then they still sell tickets for around 250 euro, but only the flights on the most inconvenient travel times will be available for this price. The other flights will be up to twice as expensive.
