Mind you, once you're off the aircraft at AMS, it's generally almost as swift as BRS to get through and out to my bike / onto the train.
My experience over the years, admittedly with KLM and not easyJet on this route, is that the likely cause of the delay at BRS is the fact that the hold luggage has gone wandering at the AMS end.
This has happened to me on three occasions over the years on flights from AMS to BRS. Once fifty per cent of the passengers on the flight had their luggage left behind.
I will agree though that taxiing from the end of the runway to the apron at BRS (even from the far end of 27) is pretty quick in time terms, and often very quick if with a certain airline from across the Irish Sea.
