Two of the region’s three major airports have been running neck-and-neck in the ranking of on-time flight arrivals, according to new federal data.
For the 12 months ending in April (the most recent available), Baltimore-Washington International Thurgood Marshall Airport posted a 79.9-percent on-time-arrival rate, with Washington Dulles International Airport showing a rate of 79.8 percent. Ronald Reagan Washington National Airport trailed at 77.8 percent.
Dulles had the lowest ratio of canceled flights during that period, with 1.5 percent of expected arrivals being nixed. The cancellation rate was 2.7 percent both at Reagan National and BWI.
Data on the major carriers at each airport:
• At Dulles, dominant carrier United Airlines posted an 81.5-percent on-time rate for the 12 months ending in April, with 0.5 percent of its flights canceled.
• At Reagan National, American Airlines had a 77.5-percent on-time rate, with 2.3 percent of its flights canceled.
• At BWI, Southwest Airlines had an 80.3-percent on-time rate, with 3.3 percent of its flights canceled.
(Data for those mainline carriers do not include regional-carrier affiliates, which are counted separately.)
Nationally for the first four months of 2019, the on-time-arrival rate was 78.7 percent. For the full 12-month period in 2018, it was 79.4 percent, with Hawaiian, Delta, Alaska and Spirit airlines posting on-time-arrival rates higher than 80 percent.
(Federal statisticians count a flight as arriving on time if it reaches its destination gate within 15 minutes of the posted timetable.)
