FARNBOROUGH, England July 22 (Reuters) - U.S. cargo
carrier National Airlines said Monday it agreed to buy four
Boeing 777 Freighters to expand its delivery operations.
National Airlines currently operates a fleet of nine 747-400
freighters that flew to 400 airports around the world last year.
"They all fly flat out," said Christopher Alf, chairman of
National Airlines, adding the carrier needs more capacity.
