LONDON, Oct 8 (Reuters) - Norwegian Air Shuttle has overtaken British Airways as the biggest non-U.S. airline on transatlantic routes to and from the New York area, in the latest illustration of the low cost carrier's move into British Airways territory.
Norwegian carried 1.67 million passengers to or from airports in the New York area in the 12 months to the end of July, compared with the 1.63 million carried by British Airways, data from the Port Authority of New York & New Jersey showed.
