While Chicago's O'Hare airport is the third busiest airport in the world, it still struggles with flight delays and other problems, and it's often a dreaded departure and arrival point. In fact, the Daily Beast recently named it the worst airport in America.
Using statistics from the Airports Council International, the site analyzed the percentage of on-time arrivals and departures, average security wait time during peak travel hours, average percentage of on-time departures on holidays, and airport comfort and amenities. After crunching the numbers, O'Hare made the top of the dubious list, with only 67.6% of on-time arrivals, 70.3% of on-time departures, and a measly 639 out of 1000 for its amenities score. Coming in second was Newark Liberty International, which handles only half the total passengers that O'Hare does in a single year.
Travelers to Chicago might want to consider the alternative, the Midway International airport, but it didn't do much better -- it comes in at number 7 on the list.
