An update in connecting in BLL: I flew in last weekend on KLM. There was a passport spot check on exiting the aircraft, with a bank of approx 6 officers with ad hoc desks set up. I was asked to show my BP for the flight departing from BLL but It all proceeded very smoothly and fast and I was back upstairs in the departure area in less than 5 minutes. I was however among the very first off the aircraft. I suspect that those sitting at the very back of the aircraft would have had more of a wait but, all in all, with the number of staff deployed for a single E90 aircraft, I would have thought that this should have been reasonably swift.
