After a weekend with hundreds of flight cancellations and delays, things are running much smoother Monday at Hartsfield-Jackson Atlanta International Airport.

Thunderstorms, high winds and hail combined to create a pretty rough summer weather scenario for Hartsfield-Jackson Atlanta International Airport this weekend.

Rough weather struck the carrier’s Atlanta hub. Airlines have canceled more than 2,800 U.S. flights since Friday.

After thousands of flights were canceled or delayed this weekend, operations have improved at the World’s Busiest Airport.
