Passengers on British Airways Flight BA104 from Dubai to London faced extreme discomfort when an air-conditioning fault grounded their Boeing 787-9 Dreamliner amid record-breaking temperatures in Dubai on May 24, 2025.
The aircraft was delayed on the tarmac at Dubai International Airport for approximately two hours due to a failure of the Auxiliary Power Unit (APU), which supplies power to the cabin cooling system while the plane is on the ground.
This malfunction prevented airflow and cooling, leaving passengers trapped in a cabin that reached temperatures as high as 47ºC (116.6ºF).
After boarding, the plane pushed back from the gate and began taxiing but had to stop when a cockpit warning light appeared. With the original gate occupied, the aircraft was diverted to a remote cargo area, prolonging the delay and the oppressive heat inside the cabin.
Passengers described the conditions as unbearable, with some children stripped down to diapers to cope with the heat.
Flight attendants distributed only one cup of water per passenger, citing concerns for their own safety due to the extreme temperatures. One passenger with high blood pressure reported feeling physically and emotionally distressed during the ordeal.
British Airways issued a statement thanking customers for their patience while the technical issue was resolved and confirmed the flight departed for London after repairs were completed.
The airline emphasized that crew members worked hard to maintain passenger comfort during the delay.
The incident coincided with a day of record-breaking heat in the UAE, with temperatures soaring to 47ºC in Dubai and exceeding 50ºC in other areas. The nearby Sweihan region recorded a May record high of 51.6ºC, surpassing the previous day’s record of 50.4ºC.
This event highlights the challenges airlines face operating in extreme heat conditions and raises questions about passenger safety and comfort during technical delays in such environments.
