By the numbers: We’re expecting Memorial Day weekend to be the busiest since 2010, with 53,515 flights on the Thursday before and 50,129 on Friday. This bodes for a very busy summer, with June 30 forecast to be the busiest day with 53,785 flights.

Delays: Weather is by far the leading cause of delays, followed by flight volume and runway capacity constraints. We’re taking extra steps this summer to mitigate these.  

What we’re doing: The FAA’s Command Center works closely with airlines, weather experts at each Air Traffic Center, and the National Weather Service to improve forecasts and to plan for, and around, expected bad weather.

We’re using updated Severe Weather Avoidance Plans and new alternative Escape Routes to get planes safely around convective weather and turbulence.

To alleviate expected heavy traffic in the Northeast and down the East Coast, we’ll continue using more efficient, high-altitude routes. We also will work collaboratively with international air traffic control facilities to move overseas flights into the United States safely and efficiently.  

Commercial Space: The FAA is ensuring that the increase in commercial space operations does not cause delays.  New operators are joining the Space Data Integrator which helps us reduce airspace closure times for launches and reentries.  

On the ground: New surface safety technologies will improve runway safety and allow smoother operations at airports. And we’re now using Integrated Departure/Arrival Capability (IDAC) at six South Florida airports to improve ground efficiency there.  

For travelers: We have extensive resources to help travelers plan ahead. The FAA X posts a daily Air Traffic Report and Weather Squad travel outlook video which highlight potential weather disruptions.  

Our summer travel page offers helpful information, including tracking airport status nationwide, tips on flying with children and how to pack safely.  

No bad behavior: And please remember, pack your patience and respect too. The FAA has a zero-tolerance policy toward unruly airline passengers.
