The new Dreamliner has touched down for the start of its first UK tour. The Boeing 787 is quieter and more fuel efficient than any other plane.
Strict noise limits mean most flights are banned at Heathrow between 11:30pm and 6am. In fact just 16 planes are allowed during that time.
But Meridian can reveal that airlines want quieter planes to land until 1am and start again at 4am.
