Well direct flights from Glasgow to Marseille only friggin start on 24th Feb with Ryan air.
Got a flight back ok for ??6-99 + the usual taxes.
Needed a bit of lateral thinking for getting out.
Flying Glasgow to Paris on the 22nd for ??2-99 + taxes, then catching the train to Marseille for ??16 (takes 3hrs) info at http://www.raileurope.co.uk/
Just booked at 7-00pm so still bargains to be had out there.
Hope this info is of use to someone.
