Years of strong growth at the Charlottetown Airport are continuing into 2008.

About 62,000 passengers moved through the airport in the first four months of the year, 8,000 more than in the first months of 2007, a 15 per cent increase. The airport has been experiencing regular double digit growth since setting a new record for passengers in 2006.

Airport CEO Doug Newson told CBC News Thursday it is difficult to determine exactly where the new passengers are coming from.

"Some of them probably just wouldn't have travelled at all, others might have gone through another airport, or some may have driven," said Newson.

Newson said a new direct flight to Ottawa is helping with traffic. As well, as the busy summer season begins, direct flights to Boston and New York will start up. The Boston flight was first offered last summer, and the New York flight is entirely new.

"It seems recently when we add extra capacity, the market has responded and people are continuing to support [the airport]," he said.

"When you add extra seats it adds competition and adds competitive airfares for the most part and that stimulates a little extra traffic as well."

The two flights to the United States begin this weekend. The Boston flight will be daily, starting Friday. The New York flight also starts Friday, but will go Friday, Saturday, Sunday only.
