A spokesman for American Airlines said the plane had turned around after a medical emergency and that it was not security-related.
He said it was not clear whether any members of crew were affected.
He added: ‘American Airlines Flight AA 109, a Boeing 777-300, operating to Los Angeles International Airport (LAX) from London Heathrow, is returning to Heathrow due to a medical emergency.
‘The aircraft departed London Heathrow at 1205 local time and is expected to land at Heathrow at 1700 local time. We apologize to our customers for the inconvenience to their travel plans.’
Equilibrium loss during air travel occurs when the air pressure in the middle ear fluctuates due to a change in altitude or imbalance in cabin air pressure.
