Etihad Airways announced on Sunday fourteen flights into Abu Dhabi are being diverted to other airports in the region due to unexpected fog at the airport, while some departing flights have been delayed for up to three hours.
The fog significantly reduced the number of aircraft that could land each hour between 6am and 8am, it said in a statement issued at 9am.
The flights were diverted to Al Ain, Al Bateen and Al Maktoum International Airport in the UAE. They will re-position back to Abu Dhabi when they have re-fuelled and the fog has cleared.
As a result Etihad is anticipating delays to departures for the rest of the day, the statement added.
The Abu Dhabi carrier advises passengers to contact the Etihad Airways Contact Centre on +971 (0) 2599 0000 or visit the Etihad Airways website for delays of the status of their flight.
An Emirates spokesperson confirmed that its flights into and out of Dubai were operated as normal.
Update - 09:41am: Etihad announced some flights departing from Abu Dhabi Airport could be delayed by up to three hours. As a result passengers who may miss connecting flights will be re-booked on later flights or alternatively provided with hotel accommodation, where necessary.
Update - 11:20am: A spokesperson for Dubai Airports confirmed Dubai International Airport has not been affected by the fog.
Update - 13:50pm: Etihad Airways said "several hundred" passengers who missed their connecting flights as a result of the severe, unexpected fog at Abu Dhabi Airport this morning have been re-booked on flights this afternoon and tonight. More than 260 other passengers who have been re-booked on flights tomorrow have been provided with hotel accommodation. The Abu Dhabi carrier said it expects to resume normal operations later today.
