British Airways to Sao Paulo entered a hold after takeoff from London Heathrow on evening.
British Airways BA247 departed London Heathrow at 22:25 GMT but stopped the climb at 20,000 ft over South coast.
The crew had to deal with cargo fans issue as the A350-1000 (registration G-XWBF) is carrying a live cargo.
Pilots decided to carry on the flight to Sao Paulo. The aircraft climbed to cruise altitude of 36,000 ft but after crossing The Atlantic, the flight was planning to divert to Fortaleza.
However the Airbus plane is now heading to final destination. The flight is scheduled to land in Sao Paulo at 06:00 BRT after more than 12 hours of flight.
