We fly with Thomson, on a package from Doncaster. We've had the same flight times, every year for the past six years. We are due to fly out in three weeks time and no changes (so far!).
Re 2018 prices, we've booked for the same two weeks next year, from Doncaster, on a package, staying at Mathraki - it's £100 cheaper than this year. Two weeks, for two of us total £767
