So, just recently on another Easyjet flight, departing Basel, we were informed not to fasten our seatbelts upon boarding as the aircraft was being re-fuelled (refuelled?) .. I was under the impression that this type of thing was done away with or illegal ,, seems not. Back in the day i remember airlines in North Africa doing it, but i have not come across it in the past decades. Turn around times starting to erode safety measures ?
