An airline is under fire for flying an aircraft across the Atlantic with only five passengers. The Boeing 777 used 22,000 gallons of fuel to take the five from Chicago to London.

It led to American Airlines being accused of reckless behaviour by green lobby groups, reports the Daily Telegraph. Friends of the Earth said it was 'obscene' to waste so much fuel flying an almost empty plane

It's estimated each passenger was responsible for 43 tons of CO2 - enough to carry a Ford Mondeo around the world five times.
