WASHINGTON — Frustration filled Reagan National Airport as travelers faced mounting flight disruptions amid the ongoing federal government shutdown, which reached its 40th day on Sunday.

Locally, Dulles International reported 45 cancellations, Baltimore/Washington International Thurgood Marshall Airport reported 39, and Reagan National saw about 95.
