LONDON - ADVERTISERS aiming to reach high-flyers with no alternative distraction will soon have a new method: adverts the size of three football pitches seen by plane passengers coming in to land.

UK-based Ad-Air launched its new service in London on Tuesday, offering brands the chance to place huge adverts near the runways of some of the world's busiest runways.

Ad-Air, backed by 5 million pounds (S$14.9 million) of private equity finance, said it had spent five years securing sites around the world's busiest airports including London Heathrow, Paris, Geneva, Atlanta, Los Angeles, Tokyo and Abu Dhabi.

The first advert will appear in Dubai next month.

Paul Jenkins, managing director of Ad-Air, said the adverts would appear in 'clutter-free environments and moments free of any other commercial messages'.

Operations Director Haakon Dewing said the adverts could develop to produce a moving image that starts each time a plane comes into sight.

The adverts, which are low to the ground and 20,000 square metres in size, will only be illuminated where local legislation allows.
