Apparently they charge you for this service even if you print it off the internet and fax it yourself
They're not the only NW London airfield to charge for this 'service' even when you do it all yourself!
LondonJ,
It's often a good plan to do your return flight plan as soon as you reach Le Touquet so that you're all set to go as soon as you return to the terminal.
As MikeJeff says, there's no need for prioir notice of your arrival at Le Touquet since they're a full-time Customs field, now with scheduled flights from Shoreham as well as the Trislanders from Lydd.
