There were 1,200 flights that were scheduled to leave.
The cancellation of flights is necessary for both safety and to make sure as many people as possible get to their flights.
People who are affected will be contacted by individual airlines.
Technical problems with baggage handling equipment led to the cancellation of a number of flights.
Thousands of aviation jobs were lost during the Pandemic and many businesses have struggled to recruit enough new staff in time to deal with the increased demand for travel.
The airport will work with airlines to rebook passengers onto other flights later in the day, according to a spokesman.
You have the option of a full refund or a replacement flight if your flight is canceled.
As long as the flight flies on the same day, it can be an alternative.
If you and the airline can't agree on a new flight, you'll get a full refund.
If the flight was canceled with less than a week's notice, you may be entitled to compensation, but only if the airline is to blame.
If it's a direct result of the airline, you're entitled to compensation, but if it's the airport, your compensation doesn't kick in.
Virgin Atlantic said that one of their flights from London to New York has been cut in each direction.
