The so-called polar vortex that descended into the U.S. this week has wreaked havoc with airline schedules, according to statistics from industry data tracking service FlightAware. Airlines on Monday canceled 4,590 flights within, into or out of the U.S., while delays totaled 8,064. Chicago O’Hare registered the most cancellations of all the nation’s airports, both for incoming and outbound flights. The airport saw 62 percent of its incoming flights cancelled and 8 percent delayed. Airlines operating out of O’Hare cancelled 65 percent of their outgoing flights and reported delays on another 10 percent.
