Manchester Airport, which handles almost 75,000 passengers per day, said in statement today: "The safety of our passengers is our top priority, and we appreciate your patience during this time.
"Please check with your airline for the latest flight information and allow extra time today."
It confirmed the runways re-opened at 10am, saying: "As a result of the earlier closure, some departures and arrivals may still experience delays."
It urged passengers to keep in touch with their airlines for the latest information and thanked workers for their "hard work in getting the runways operational again."
It comes after the airport had to shut for three consecutive days at the start of this week.
Meanwhile British Airways revealed it has so far de-iced 543 aircraft before take-offs to ensure flights can safely go ahead.
If frost, ice or snow contamination is observed or suspected a plane must undergo de-icing before take-off.
It takes just five minutes to de-ice a BA A320 jet and takes place with passengers onboard.
Spencer Norton, manager for flight efficiency and evaluation, helps run BA’s ‘Snow Patrol’ - helping identify where de-icing needs to take place on a plane's fuselage.

"We’re there to assist our captains to ensure that we can do a good visual and tactile check of the aircraft services to provide them with the best info to see if they need to de-ice or anti-ice in the circumstances.”
