After entering UK skies, the flight from Las Vegas to London declared a mid-air emergency, according to the British media outlet.
The emergency was announced when the plane was flying over the north-west coast of Ireland, according to the Express.
The Boeing 747 jet was scheduled to reach Heathrow at 3:30 pm after it departed from Las Vegas at 9:30 pm local time.
The Flightlevel250 Twitter account, which is dedicated to aviation, reported that the incident was indeed an emergency, and it is "under control" now.

However, the Daily Star Online said later in the day, citing a British Airways spokesman, that the aircraft had not declared an emergency.
This comes after on 19 April the Daily Mail reported another incident when an emergency was declared as one of the passengers fell ill an hour away from London. The incident was confirmed later that day by a British Airways spokesperson.
