An American Airlines Boeing 767-300, registration N377AN performing flight AA-65 from Zurich (Switzerland) to New York JFK,NY (USA) with 151 passengers and 11 crew, was enroute at FL340 about 120nm northwest of Paris Charles de Gaulle (France) when the crew decided to turn around and divert to Paris Charles de Gaulle reporting fumes on board. The aircraft landed safely in Paris about 35 minutes later. Emergency services transported two flight attendants to a hospital. A passenger tweeted there were fumes on board causing two flight attendants to become ill and incapacitated. A number of passengers complained about nausea and headache, however, the passengers were kept on board for about 4 hours until the flight was cancelled. The aircraft had already been a replacement aircraft flown in from Madrid,SP (Spain) and had departed Zurich with a delay of 8 hours (editorial note: the incoming flight AA-64 departing JFK on Jun 3rd had been cancelled prior to departure). The airline reported the aircraft diverted to Paris due to an odour on board. The aircraft is being examined. N377AN is still on the ground in Paris about 25 hours after landing.
