Air travellers have been warned flights could be delayed due to thick fog blanketing Brisbane.

Brisbane residents have woken to a pea soup fog with travellers warned of likely flight delays.

City residents have been sharing photos of the thick blanket of fog sitting heavy over the city, with only the tips of the CBD towers visible from Mount Coot-Tha.

Brisbane Airport says the fog has slowed operations and there may be delays to some flights.
