The Government is proposing no change to the number of night flights at Heathrow. The consultation document, released last week by the Department for Transport, argues that the current regime should continue for the next five years. It will then be clearer whether a third runway will be underway. Permission to build a third runway is expected to be conditional on a tougher night flight regime being introduced when it opens.
At present an average of 16 flights each night are allowed to land at Heathrow between 11.30pm and 6am. There are no scheduled departures during this period. The first flight lands at 4.30am.
