A British Airways flight attendant died onboard a plane as it was preparing to fly from London to Hong Kong

• A British Airways flight attendant died on a plane as he was preparing for take-off, Metro reported.
• He was set to fly from London to Hong Kong on December 30, per the report.
• "Our thoughts are with our colleagues' friends and family at this incredibly sad time," a BA spokesperson said.

A British Airways flight attendant died onboard a plane shortly before it was due to depart from London for Hong Kong, reports say.

Metro reported that a 52-year-old male flight attendant was preparing for take-off on December 30 when he fell to the floor. A passenger administered first aid after the captain called for help, the publication reported.

A London Ambulance Service spokesperson told Business Insider that it was called to Heathrow's Terminal 5 at 5:45 p.m. on December 30 and dispatched an ambulance crew, a medic in a fast-response car, a paramedic on a bicycle, and a trauma team.

"Sadly, despite the best efforts of our crews, a patient was pronounced dead at the scene," the spokesperson said.

Passengers were booked into hotels nearby and departed on a flight the next day instead, Metro reported.

British Airways operates daily 13-hour flights on route BA31 from London Heathrow to Hong Kong, departing at 5:40 p.m. local time.

Records from flight-tracking site FlightAware indicate that no flight departed on that route on December 30, and that two flights flew that route on December 31 instead.

"Our thoughts are with our colleagues' friends and family at this incredibly sad time," a British Airways spokesperson told BI.
