American Airlines plans to stop its daily flight between Chicago's O'Hare International Airport and Brussels, Belgium, on Nov. 6. American spokesman Jim Faulkner said Friday that it was a variety of factors that led to the decision. "High oil prices, a weakened global economy and reduced travel demand have all affected the route's performance, making it unsustainable in the long term," Faulkner said. He noted that American would continue to serve Brussels with its daily flight from New York's Kennedy International Airport. American began service to Brussels from Chicago and New York in May 1989. The carrier discontinued the New York-Brussels flight in October 1997, then resumed it in May 2004.
