Travelers using the Washington area’s three main airports during the first six months of 2019 were most likely to find their flights departing on time at Washington Dulles International, according to new data.
And all three facilities saw improvement in their rankings compared to the nation’s other large U.S. airports.
Dulles ranked first in the region, and fifth among the 30 largest airports, with an on-time rate of 81.99 percent, according to new departure data from the federal Bureau of Transportation Statistics.
Dulles bumped up from seventh place among the top 30 airports during the same period in 2018, although its average on-time percentage declined slightly from 2018 to 2019.
Among the region’s two other airports:
• Ronald Reagan Washington National Airport reported an on-time-departure rate of 78.51 percent for the first six months, ranking it 15th nationally. A year before, it had been 22nd at 77.27 percent.
• Baltimore-Washington International-Thurgood Marshall Airport posted an on-time-departure rate of 76.36 percent, ranking it 19th nationally. A year before, it had been 21st at 77.57 percent.
Nationally, Portland (Ore.) International Airport had the highest on-time rate for the first six months of the year among large airports, at 87.27 percent. It was followed by Salt Lake City (84.72 percent), Minneapolis-St. Paul (82.77 percent), Seattle (82.31 percent) and Dulles.
On the other side of the coin was Chicago-Midway, whose on-time rate of 65.72 percent was lowest among the 30 largest airports. It was followed in the hall of shame by Newark-Liberty (70.75 percent), Dallas Love Field (71.31 percent) Chicago-O’Hare (72.1 percent) and Dallas-Fort Worth (73.02 percent).
When it comes to on-time arrivals, BWI-Marshall was best in the region for the January-to-June period at 82.05 percent, ranking sixth nationally. Dulles was 10th at 79.48 percent, with Reagan National 19th at 77.26 percent.
Nationally, the highest on-time-arrival rates for the first half of the year were at Atlanta Hartsfield-Jackson (84.13 percent), Salt Lake City (83.35 percent) and Portland, Ore. (82.73 percent). The lowest rates were at Newark-Liberty (64.93 percent), New York La Guardia (69.07 percent) and San Francisco (69.91 percent).
The federal government counts a flight as “on time” if it leaves and/or arrives within 15 minutes of its scheduled time.
