No. 7 Chicago O’Hare International Airport (ORD)
Flights Delayed: 21.4%
The best one can say about O’Hare’s standing is that it could have been worse, given its years-long bad reputation. (Back in 2008, your overall odds of getting delayed were 35 percent.) After a few years of steady improvement, on-time performance went down one percentage point this year.
Best Time Window: Before 7 a.m.
Worst Time Window: 5–11 p.m.
