US Airport Delay Overview
On-time performance across US airports, updated every 15 minutes from the FAA
Worst Performing Airports
Airports with the lowest on-time performance right now
4 of the 5 sit in the Northeast corridor, where congested airspace means one backup cascades to the rest. If you're connecting through any of these, pad your layover or reroute.
Best Performing Airports
Airports running the smoothest operations today
If you have flexibility on your connection point, these are safe bets.
OTP Distribution
Where most airports fall on the OTP scale
Spread day. 30 airports below 60%, 20 above 80%. More pain than usual across the system.
Regional Performance
Where delays cluster and where you're clear
The East is the sore spot at 34% departure OTP across 29 airports. Central airports are running the cleanest at 61%.
7-Day Trend
How the week played out and which days to target
Monday dipped to 60%. Wednesday was the best at 80%. If you have flexibility, weekends are consistently the best days to fly, running above early-week averages.

About Airport Delays
The FAA monitors 179 airports with real-time delay data. This dashboard shows live on-time performance for all 177 airports currently reporting, updated every 15 minutes.
The on-time percentage represents the proportion of flights departing or arriving within 15 minutes of their scheduled time. An airport with 85% on-time means 85 out of every 100 flights are on schedule. Anything above 80% is considered good performance.
Delay data is sourced from the FAA and updates every 15 minutes. Historical views (past hour, 24 hours, 7 days) use weighted averages that account for flight volume, giving busier time periods more influence on the numbers.
Airport delays are typically caused by weather (thunderstorms, fog, snow), air traffic volume, runway capacity constraints, staffing issues, and cascading effects from earlier disruptions. Delays tend to worsen throughout the day as problems compound.
Book early morning departures — they have the highest on-time rates since there are fewer cascading delays. Check this dashboard before heading to the airport, consider nearby alternative airports when your airport shows major delays, and allow extra time during peak travel periods.
