Quite. If you ever spend time looking at FlightRadar24, flights from places like Brussels can do the journey in about half the allocated time if they are lucky or at an off-peak time and get 'straight in' - I'm sure there must be a technical term for this - yet at busy times there are planes doing three or four rotations in the queue before landing.
