Spain: fuelling while boarding prohibited unless airport fire service in attendance
Not strictly true. At certain Spanish airports you can fuel with the fire crews 'In Alert' as opposed to 'In Attendance' (actually at the aircraft). In Alert means they are notified which aircraft/ stand is fuelling with pax on and don't attend as routine. I believe they have a limit (2 a/c from memory) that can use In Alert at any one time. You have to request it through the handling agent on arrival and they tell you if you can or not.....
