United Flight Returns to Heathrow After Cabin Odor

United Flight UA941 returned to London Heathrow on Thursday after turning back over England during a trip to Newark, New Jersey.

The Boeing 767 had climbed to about 32,000 feet over Manchester when the crew declared an emergency and headed back to London.

United said an odor in the cabin prompted the return, but the source of the smell was not established.

The plane landed safely after about two hours in the air, and passengers left normally.

United canceled the flight and began rebooking passengers, also providing hotel vouchers to affected travelers.

The incident matters because passengers were left needing new arrangements to reach Newark, and eligible travelers may have rights to assistance under UK rules.

United said it was working to get passengers to their destinations, but no replacement flight timing was confirmed in the available information.
