According to the FAA’s Air Traffic Control System Command Center, the average delay was a little more than two and a half hours. At one point, the maximum delay stretched to 714 minutes.

Orlando International Airport is one of the busiest in the U.S. and processes an average of 155,000 passengers each day, according to airport traffic statistics.
