major expansion of the cargo facilities. A new control tower has been built. In the fourth quarter of 2007 Interstate 84's new Drury Lane exit, NY Route 747, and International Boulevard opened. In addition to commercial and passenger services, Stewart excels in many other areas not seen by the public. NEG had some success selling private helicopter shuttle service to midtown Manhattan's heliports to business travelers from Stewart at rates competitive with those offered from JFK Airport; it also remains a popular place to service corporate jets due to the large space available. Cargo services are also part of the mix – FedEx Express maintains a large distribution presence just outside the airport, as does the U.S. Postal Service, whose main general-mail facility for the mid-Hudson region is not far away. Importers of plant and animal products also route their flights to Stewart and the USDA inspection facility for those is nearby, on Drury Lane. In 2005, the airport was used to transport emergency personnel and supplies to help the cleanup after the destruction of Hurricane Katrina, which devastated the Gulf Coast. With its long runway, Stewart bills itself as an "efficient diversion airport" for aircraft intending to land at one of the three major New York City airports (Newark, LaGuardia, and JFK), especially during bad weather. The largest such diversion occurred during the January 2018 blizzard, when a Singapore Airlines Airbus A380 on a Frankfurt-JFK flight diverted to Stewart after JFK closed. While the airport's runways are sufficiently long to allow such a large aircraft to land and take off, the plane was so large it could not use any of the terminal building's gates. Passengers had to leave the plane using stairs, and were transported to New York City by bus. American Airlines, which had served Stewart since 1990, ended American Eagle regional jet service to Chicago O'Hare International Airport on September 5, 2007. In 1991, American was operating up to five mainline departures a day nonstop to Chicago O'Hare with Boeing 727-200 jetliners. In 2008, AirTran Airways ended service to Stewart International Airport. The Port Authority sees Stewart as offering relief to those airports and (especially) Teterboro, estimating it could handle five times its present passenger volume. It will probably follow its standard procedure and contract the actual operations of the airport out. In February 2008, the PA's new general manager, Diannae Ehler, said she had been
