Worst: No. 5 Denver International Airport (DEN)
Flights Delayed: 23.3%
Denver International—known for its art installations and quirky aesthetics—now has the added feature of occasionally making time stand still. In the evenings, your odds of departing late are 1 in 3. There is a bright side: its period of morning efficiency (fewer than 15 percent of flights delayed) lasts until a pretty civilized 10 a.m.
Best Time Window: Before 10 a.m.
Worst Time Window: 5–9 p.m.
