An American Airlines flight from Rome to Philadelphia diverted to Dublin on Saturday after a reported odor onboard prompted medical evaluations for several people.

Flight 719, a Boeing 787-9 Dreamliner, departed Leonardo da Vinci International Airport (FCO) around noon local time but diverted to Dublin Airport roughly three hours into the trip, according to FlightAware.

An American Airlines spokesperson told FOX Business that the reported odor was traced to an oven onboard the aircraft.

Aviation insider JonNYC reported that several flight attendants may have fallen ill during the incident. One person onboard also reported what was described as "decompression and lower oxygen levels" near the front of the aircraft, JonNYC said.

The Boeing 787 was carrying 281 customers and 12 crew members, the airline said.

After the plane landed in Dublin, paramedics met the aircraft at the gate out of an abundance of caution, according to American Airlines. Several flight attendants and one customer were reportedly evaluated by medical personnel and later released.

American Airlines said affected customers were provided hotel accommodations at no charge and continued to Philadelphia International Airport on alternate flights the next morning.

The incident is a reminder that even a diversion prompted by an onboard odor can quickly become an operational and medical response, with crews, airport responders and airline staff coordinating to care for passengers and reposition travelers on alternate flights. In long-haul service on aircraft such as the Boeing 787, any report involving possible fumes, illness or cabin air concerns is treated seriously because it can affect both the flight’s immediate handling and the timing of the onward journey.

"We appreciate the understanding of our customers and thank our team members for their professionalism," the carrier said.
