Pan Am’s Sale of Routes to Close...

Pan Am’s Sale of Routes to Close Today: United Airlines is expected to close its purchase of Pan American World Airways’ European routes, but the deal could fall apart if the British government forbids transfer of Pan Am’s authority to use London’s Heathrow Airport. Without the coveted access to Heathrow, “the deal is off,” Lawrence M. Nagin, general counsel of United’s parent, UAL Corp., said in an interview from London. If the sale collapses, Trans World Airlines Chairman Carl C. Icahn could renew his offer for Pan Am Corp., the airline’s parent. Icahn has offered $450 million for Pan Am, but his offer expires Friday.
