NEW YORK ( TheStreet) -- Give the MidEast airlines credit for this: They are serving the luxury end of the airline business, where the U.S. airlines -- despite their rush to install lie-flat seating -- are not yet fully competitive. Etihad Airways said Wednesday that starting Dec. 1, it will fly Abu Dhabi-New York with an Airbus A380 that includes luxury, three-room private suites, complete with butlers.
