This article explains what happened, why these ground delays occur, how they affect travelers, and what steps you should take if you’re flying through IAH Airport during severe weather. We’ll also look at the recent improvements at the airport, expert advice, and what the future holds for travelers in Houston.
What Is a Ground Delay and Why Does It Happen?
A ground delay is when the Federal Aviation Administration (FAA) or airport officials temporarily stop or slow down flights from taking off or landing at an airport. This usually happens for safety reasons, such as severe thunderstorms, heavy rain, or other dangerous weather. During a ground delay, planes may be held at their origin airport, or they may have to wait on the ground at IAH Airport before taking off or after landing.
Severe thunderstorms are a common cause of ground delays at IAH Airport, especially during the spring and summer months. Houston’s location makes it especially vulnerable to sudden storms, which can bring strong winds, lightning, and heavy rain. These conditions make it unsafe for planes to take off, land, or taxi on the runway.
Timeline of Recent Ground Delays at IAH Airport
- May 2, 2025: Severe thunderstorms led to a ground delay at IAH Airport, halting all departures until at least 10:30 p.m. There was a 30–60% chance the delay would be extended, depending on the weather.
- May 26, 2025: Another ground delay was issued at 1:35 p.m. due to scattered thunderstorms. The average delay was 64 minutes. The delay was lifted by 5 p.m. as the weather improved.
- May 28, 2025: IAH Airport returned to normal operations, with only minor delays of 15 minutes or less.
These ground delays affected thousands of travelers, many of whom missed connecting flights or had to wait for hours at the airport.
Current Status: IAH Airport Back to Normal

Only minor arrival and departure delays, usually 15 minutes or less, have been reported. Travelers can check the latest updates on the official FAA flight status page for IAH Airport.
Recent Improvements at IAH Airport
In May 2025, IAH Airport introduced a new expedited TSA PreCheck lane for international arrivals in Terminal E. This new lane helps eligible passengers move through security checks faster, making it easier for them to catch connecting flights. According to Jim Szczesniak, Director of Aviation for Houston Airports, these improvements are part of a larger effort to handle more travelers and recover quickly from disruptions.
During Spring Break 2025, IAH Airport handled over 2.3 million travelers in just 12 days—a 6% increase over the previous year. This record number shows how important the airport is for both domestic and international travel.
How Ground Delays Affect Travelers
Ground delays can cause a chain reaction of problems for travelers:
- Missed connections: If your first flight is delayed, you might miss your next flight, especially if you have a tight layover.
- Rebookings: Airlines may automatically rebook you on a later flight, but these changes might not always match your needs.
- Long wait times: You may have to wait at the airport for hours, sometimes overnight, until flights resume.
- Confusing communication: Sometimes, airlines’ automatic systems make mistakes. For example, United Airlines recently canceled a flight segment by mistake, then reinstated it, but most passengers had already been rebooked on later flights.
What Should You Do If You’re Affected?
- Monitor official sources:
- Check the IAH Airport website and the FAA status page for real-time updates.
- Sign up for alerts from your airline and the airport.
- If a ground delay is announced:
- Expect all departures to be temporarily stopped. Arrivals may also be delayed or held at their origin airports.
- Airlines will send updates by email, text, or app notifications.
3. If your flight is canceled or delayed: - Use your airline’s app or website to check for rebooking options.
- Contact the airline directly to confirm your new flight and ask about other options.
- Double-check your new itinerary and seat assignment.
- For connecting passengers:
- If you’re arriving internationally, look for the new TSA PreCheck signs in Terminal E for faster screening.
Advice from Experts and Airport Officials
Aviation experts say that Houston’s weather makes IAH Airport especially prone to sudden ground delays. The airport’s location means that thunderstorms can develop quickly, forcing officials to act fast to keep everyone safe.
Jim Szczesniak, Director of Aviation for Houston Airports, credits recent operational success to investments in infrastructure and careful planning. He says these improvements help the airport recover faster from disruptions, especially during busy times like Spring Break.
Experts also recommend that travelers:
- Stay proactive: Don’t wait for the airline to contact you. Check your flight status often, especially if storms are in the forecast.
- Communicate directly: If your flight is delayed or canceled, call the airline or use their app to get the latest information and rebooking options.
- Be prepared: Bring snacks, water, and chargers in case you have to wait at the airport for a long time.
Multiple Perspectives: Passengers, Airlines, and Airport Officials
Passengers:
Travelers often feel frustrated when ground delays cause them to miss connections or spend hours waiting at the airport. The recent United Airlines incident, where a flight segment was canceled by mistake and then reinstated, left many passengers confused and rebooked on much later flights.
Airlines:
Airlines face tough choices during severe weather. They must balance safety, logistics, and customer service. Automatic rebooking systems are meant to help, but they don’t always reflect real-time changes, which can lead to mistakes.
Airport officials:
The Houston Airport System focuses on safety and clear communication. They use new technology and improved infrastructure to keep disruptions as short as possible and help travelers get back on track quickly.
