These are the frequencies for 2018 with 2017 in brackets, it's very early days and we probably won't see the final schedule until well into the winter so expect changes (good or bad).
New are weekly Girona, Thessaloniki and Varna with 2x weekly Palma and a weekly Heraklion being cut. Hurghada also sees an extra flight so we're +1 weekly, as it stands. Naples for this year is showing Tue and Fri but on Thomson, next year it's only showing Fri, again on Thomson. No sign at all of Preveza (it's bookable from BRS) so it could just be seats bought on the Monarch service. Sharm returns this December but only runs until the end of April, if things go well there may be scope to carry it through the summer.
