At least 10 American crew members were transported to local hospitals for evaluation.

“Flight 728 from Philadelphia to London Heathrow diverted to Boston after a possible odor was reported in the cabin. The aircraft, an airbus a330-300 with 154 passengers and a crew of 12 landed safely at 11:48 p.m and taxied to the gate. Our maintenance team is currently reviewing the issue,” American said in a statement.

No passengers were affected. However, several reported smelling the odor.

“I kept smelling a funny smell and I wasn’t quite sure what it was. I thought someone had an upset stomach, so I ignored it,” one woman told WBZ-TV.

Another passenger described the odor as a “strange burning smell.”

All passengers were provided overnight accommodations in Boston and will continue on to London Monday.
