WASHINGTON—Amid peak summer travel, thousands of air travelers faced flight cancellations and delays this weekend and Monday as thunderstorms rolled in across the U.S. East Coast and Midwest.
In addition to bad weather, a technology failing also contributed to airline disruptions. The Federal Aviation Administration briefly paused operations at Washington-area airports Sunday evening due to a problem with the communications system at a major air traffic control facility. Departures resumed after repairs were completed.
