There are some great things about BWI, like how close it is to the city and how easy it is to get to by public transit. And then there are the downsides โ€” like the fact that the airport has the second-highest proportion of flights delayed in the U.S., bested only by Chicagoโ€™s Midway.

A full 23.2 percent of BWIโ€™s flights are delayed, nearly one in four of every departures. That is, frankly, a lot. The only silver lining is that previous worst-delay airports (like Dallas-Fort Worth) saw improvement this year. But the odds arenโ€™t good, as the on-time performance got worse by two full percentage points this year.

Ways to combat BWIโ€™s delay-prone tendencies? Flights leaving before 8 AM are a better bet; avoid the 3-11 PM departures. Or fly out of Dulles (16 percent of flights delayed) or Reagan (13.7 percent).
