The US has significant A380 development in May. British Airways will deploy the double-decker quadjet between London Heathrow and Washington Dulles, Korean Air will use the type from Seoul Incheon to New York JFK, and Lufthansa will fly it from its Munich hub to Dulles. Only one of these three routes is brand-new for the A380; the rest are resumptions. Etihad recently returned the A380 to JFK.
