Flight cancellations across the U.S. eased ahead of a House vote on a funding bill to end the longest government shutdown in history. 811 U.S. departures were canceled on Wednesday, 3.5% of airlines’ schedule, the lowest rate since last Thursday. Air traffic controller staffing shortages led to disruptions impacting 5 million passengers.

U.S. airline shares rose before the House vote. Thousands of flights were slowed or canceled during the shutdown, affecting millions of passengers.
