DCA ranks as least reliable airport in 2026
DCA leads the nation in cancellations (2.8%), according to the report, which used data from the Federal Aviation Administration and the U.S. Department of Transportation, and cancels its last flight of the day, more than any other large airport in the country.
But, not all the blame can be placed on DCA itself. According to ConsumerAffairs, nearly half of their delays are caused by flights showing up late. That's more than any of the five worst major airports.
