More than 1.5m people used Southampton Airport last year

The idea is part of a draft plan released by the airport to outline its strategy for the next 25 years.

It predicts passenger numbers will rise from the current 1.5m to 6m by 2030 and in the process more than 4,000 jobs will be created.

Concerns have been raised by the council, which said the expansion could cause congestion, pollution and noise.

As we grow, we aim to build upon our reputation as one of Europe's leading regional airports David Cumming, MD of Southampton Airport

Councillor Tim Knight, said: "We welcome the fact that the airport is consulting local people on its plans for growth.

"It's a valuable asset and helps to boost the local economy, and it's good to have an international airport so close to home.

"However, airport growth can also add to problems of congestion, air pollution and noise for residents, and we must take into account too the impact on transport links and employment growth."

Biggest rise

David Cumming, managing director at Southampton Airport, said: "Over the next 25 years we will continue to support the growing commercial, leisure and cultural success of the region in a responsible and sustainable way.

"As we grow, we aim to build upon our reputation as one of Europe's leading regional airports.

"Our intention is to remain a regional airport, rather than to grow to the size of airports such as Heathrow or Gatwick."

Hampshire County Council will consider the plans and the airport is encouraging the public to give their views.
