The airport's $3.8 billion renovation is inching toward completion with new parking garages, roadways, terminal space and more.
A new terminal complex will be 521,000 square feet with 34 gates, compared with 24 gates in slightly less than 446,000 square feet of terminal space now.
"A takeoff slot at J.F.K. requires terminal space, a parking gate and a landing slot somewhere else," said Giovanni Bisignani, the group's director general.
Further, he said, airlines are creating complications for themselves by trying to apportion landing slots, aircraft, terminal space and the personnel needed to run the new carriers.
Proposals for the terminal space have been submitted to the city's Economic Development Corporation, which is spending more than $30 million to restore the exterior.
Over a million square feet of terminal space will be added to the airport.What does all this mean for business travellers?
The need to expand the terminal space at Penn Station has long been established, they said, and should not be confused with a separate need to improve fire and safety conditions below ground.
But so are the airports themselves, with landing-fee revenue off sharply amid uncertainties about whether airlines will make timely payments on fees they pay to rent terminal space.
But city officials cast a vote of confidence on Monday in the future of Los Angeles International Airport, awarding contracts for a major overhaul of the airport's international travel facilities, including adding more than one million square feet of terminal space.
Airports with two simultaneous runways should be able to handle approximately 55 to 65 million passengers per year, and here, too, the main capacity problems are related to the provision of adequate terminal space.
