LFQO?
The field is less than six km north of the centre of Lille. Looking at Google earth it would seem to be a DZ called Lille Bondues. I usually find DZ's quite welcoming. If you look on google earth you can actually see two parachutes touching down and one plane taxiing in! Two 850m runways that look to be in very good condition.
If you are a smoker it may be worth basing at Kortrijk, its only 20 minutes away and the cigg's are a lot cheaper than France. Also Bernard is a very good engineer. He services the jump plane from Chatteris as far as i know!
