Discover the airports where flight delays are the most common and how they could affect your travel plans.

Frequent flyers know the frustration of flight delays, but some airports are notorious for making passengers wait. Whether due to weather, air traffic, or logistical issues, certain U.S. airports experience delays far more often than others. Planning ahead can help you navigate these hotspots of inconvenience.
Here are ten airports known for their most frequent flight delays and tips to prepare for your next trip through these bustling hubs.
1. Chicago O’Hare International Airport often struggles with heavy traffic

Chicago O’Hare International Airport ranks among the busiest airports globally, which directly contributes to its frequent flight delays. Its location in the Midwest makes it particularly vulnerable to harsh weather conditions, including snowstorms in winter and severe thunderstorms in summer. With high air traffic volume, runway congestion often compounds the problem. Despite modernized facilities, delays remain a significant issue. Travelers should prepare for potential disruptions, monitor real-time updates, and plan flexible itineraries when connecting through O’Hare.
2. Atlanta Hartsfield-Jackson is affected by its massive size

Atlanta Hartsfield-Jackson, the world’s busiest airport, often experiences delays due to its enormous passenger volume and flight operations. Severe weather, particularly thunderstorms during summer, frequently disrupts flight schedules. The airport’s massive size can lead to logistical challenges, including lengthy taxiing times and crowded gates. Despite its advanced infrastructure, these issues persist. Travelers flying through Atlanta should consider scheduling longer layovers, booking morning flights when delays are less likely, and staying updated on weather conditions.
3. Newark Liberty International Airport is plagued by congestion

Newark Liberty International Airport serves as a major hub for the New York metropolitan area and frequently suffers from delays. Proximity to LaGuardia and JFK increases air traffic congestion, while limited runway capacity complicates operations. Seasonal weather issues like snowstorms and fog further contribute to flight disruptions. Travelers using Newark should prepare for potential delays by monitoring flight statuses, considering nearby alternative airports, and leaving extra time in their travel plans to accommodate unforeseen disruptions.
4. New York’s LaGuardia Airport suffers from limited space

New York’s LaGuardia Airport is notorious for its frequent delays, stemming from its compact size and outdated infrastructure. Located in a densely populated area, the airport operates with limited runway space, creating challenges in managing high air traffic volumes. Seasonal weather conditions, including snow and wind, often exacerbate delays. Passengers flying through LaGuardia should anticipate potential disruptions, pack essentials for long waits, and consider booking flights outside peak travel times to reduce the likelihood of delays.
5. San Francisco International Airport is vulnerable to weather disruptions

San Francisco International Airport frequently experiences delays due to its coastal location, where fog and low visibility are common issues. The airport’s parallel runway configuration further complicates operations during inclement weather, as simultaneous landings and takeoffs can become challenging. Despite modern facilities, these factors contribute to frequent disruptions. Travelers flying to or through San Francisco should allow extra time for layovers, stay informed about weather forecasts, and consider morning flights when visibility conditions are typically better.
6. Denver International Airport faces winter weather challenges

Denver International Airport is known for its winter weather-related delays, with heavy snowstorms and icy conditions being frequent culprits. The airport’s expansive size also means longer taxi times, which can add to operational inefficiencies. However, its advanced snow removal systems and dedicated crews help minimize disruptions during harsh weather. Travelers should pack warm clothing, stay updated on weather advisories, and plan flexible itineraries when flying through Denver during the winter months to avoid unnecessary stress.
7. Los Angeles International Airport suffers from air traffic congestion

Los Angeles International Airport often faces delays due to its high volume of air traffic and the complexity of managing one of the busiest airports in the world. Its location in a major metropolitan area contributes to logistical bottlenecks, particularly during peak travel times. Runway congestion and extended taxiing times are frequent complaints among travelers. Those flying through LAX should schedule flights during off-peak hours, allow ample time for connections, and monitor flight updates for potential delays.
8. Miami International Airport struggles with unpredictable weather

Miami International Airport is a hub for international and domestic flights, making it a hotspot for frequent delays. Its location in a tropical climate means unpredictable weather patterns, including thunderstorms and hurricane risks, can disrupt schedules. The high volume of passenger traffic further compounds operational challenges. Travelers should check weather forecasts and flight statuses regularly when flying through Miami, especially during hurricane season, and ensure they have backup plans for any significant delays.
9. Dallas/Fort Worth International Airport is impacted by severe storms

Dallas/Fort Worth International Airport frequently experiences delays due to severe weather conditions, including thunderstorms, high winds, and occasional tornado warnings. As one of the largest and busiest airports in the U.S., it also faces logistical challenges with its vast size and numerous terminals. Extended taxi times are common, adding to potential delays. Travelers flying through DFW should plan for possible weather-related disruptions, consider travel insurance, and schedule extra time between connections to avoid missing flights.
10. Boston Logan International Airport is hampered by winter weather

Boston Logan International Airport is known for its frequent delays during the winter months, as snowstorms, icy conditions, and coastal winds disrupt operations. Its compact layout and heavy passenger volume can exacerbate these issues, leading to long waits. Despite its advanced de-icing systems, Logan often faces challenges during severe weather. Travelers flying to or from Boston should stay informed about weather forecasts, pack essentials for comfort, and plan additional time for connections or alternative travel arrangements.
