Key Takeaways
- Major U.S. hubs like Chicago O’Hare, Dallas–Fort Worth, and Newark have some of the nation’s lowest on-time rates due to congestion and weather.
- Southern and coastal airports benefit from milder climates, helping Honolulu, Palm Beach, and San Diego rank among the most punctual in 2025.
Flight delays remain a persistent challenge across the United States. This data set shows how geography, weather patterns, and high traffic volumes shape punctuality across the national air network.
Large, high-traffic airports consistently rank lower, reflecting the strain of urban airspace, complex operations, and seasonal weather patterns. Meanwhile, airports in warmer regions, particularly in the South and along the coasts, tend to experience fewer disruptions.
The data for this visualization comes from SmartAsset and covers 75 of the largest airports in the United States.
Major Hubs Face Persistent Congestion Challenges
Long Island MacArthur Airport (ISP) ranks number one for the lowest on-time performance in the 2025 dataset, with just 60.3% of flights arriving as scheduled. Despite being a smaller regional airport, ISP faces several operational constraints that can amplify delays, including limited runway capacity, seasonal weather challenges on Long Island, and its proximity to the congested New York airspace.

The worst-performing major airports include Chicago O’Hare (64.0% on-time rate), Dallas–Fort Worth (64.9%), and Newark (63.7%). These airports manage some of the highest monthly flight volumes in the country, which increases the likelihood of bottlenecks during peak travel periods.
Cold-Weather Airports See Greater Seasonal Variability
Airports in the Northeast and Midwest tend to experience lower on-time rates due to winter storms, low visibility, and seasonal operational slowdowns.
Boston Logan (67.0%), Buffalo (65.3%), and Syracuse (65.1%) are notable examples.
Southern and Coastal Airports Lead in Punctuality
At the opposite end of the spectrum, warmer-weather airports such as Honolulu (87.4%), Palm Beach (86.1%), and San Diego (78.6%) show some of the highest on-time rates.
These regions benefit from fewer seasonal disruptions, consistent temperatures, and more predictable operational conditions.
