Flights were diverted and others grounded throughout the Midwest after a temporary outage at a Minnesota air traffic control facility caused issues, the FAA said.
The FAA will reduce flight capacity by 10% at 40 major airports across the country, officials said. ABC News has obtained a list of U.S. airports that will be impacted.
While the FAA continues to limit flights, the number of takeoffs and landings is going up by four per hour to 72, still well below the more than 80 the airport saw before the current caps were put in place.
Neither of the other major US airlines that historically offered flights to Israel, Delta and American Airlines, have resumed service yet.
Video taken by a passenger shows the flight crew spraying insect repellent as the mosquitoes buzzed around the cabin.
Heavy smoke from wildfires in Canada has impacted flights across the Northeast, including here in Philadelphia.
