Rules doubling the amount of passenger duty people pay when taking flights from the UK have come into force.
The increase was announced by Chancellor Gordon Brown last December. He said airlines should pay more for damaging the environment.
November 2007 :
Transport Secretary Ruth Kelly is set to outline plans for a third runway and possible sixth terminal at Heathrow. She will say a third, short runway will not breach noise and environmental limits as consultation begins on a huge expansion of the west London airport.
Expansion at Heathrow could see flights increase from 480,000 a year to 800,000 - a move that will anger local residents and green campaigners.
So air travel damages the environment. And we need to nearly double it.
