I've noticed that when using kayak.com or other flight searches Turkish Airline flights are very expensive ($600 from Dalaman to Nevshir). However, booking directly through Turkish Airlines website seems much cheaper (around $150 for the same flight), but mentions fuel surcharges. Does anyone who if it is safe to book directly from Turkish Airlines, and if so what the estimated fuel surcharge is likely to be. I'd prefer booking through expedia or someone like that, but the price difference is too huge. Thanks for the help.
