I just booked my flight to Turkey, unfortunately it s such a scams and not clear company as they didn t mention
clearly that I have to pay for my cargo luggage on the way back to the uk , after paying they send me a confirmation contain a red writing about paying for the luggage on the way back, which I shocked of that and consequently I called them to discuss and their response was $100 to pay from Turkey or I have to carry 23 kg inside the plain by my self .
it s my mistake to book with this company before reading the reviews!
