According to the interview of Mr. Wallop, one of Thai's board of directors, he said it is "Unavoidable" for the airline to resume flying to New York because A340-500s are still there and unable to be sold in a near future. The plan is to make all planes better utilized, add more seats from 207 to 260 (cut the Y+) and move from New York JFK to Newark EWR, which is a hub of new Star Alliance member, Continental Airlines.
