How severe weather impacts airport operations and flights

Delays caused by severe weather often result in longer processing times for baggage and additional checks before aircraft can return to service. 

Houston Airports understands how frustrating weather-related delays can be for passengers, their families and even our own operations teams. That’s why we work closely with airlines and the FAA to resume operations as quickly and safely as possible once the storm has passed. 

Safety is our top priority. While the delay can be frustrating, safety measures protect workers and passengers.

Weather and ground stops: Just like a rain delay at a sporting event, severe weather can bring airport operations to a halt. For instance, when lightning is detected around Bush Airport (IAH) or Hobby Airport (HOU), ground crews must immediately stop working outdoors and seek shelter until the threat passes. The Federal Aviation Administration (FAA) enforces this safety requirement.

These events, called ground stops, affect flights scheduled to take off and can also delay inbound flights, causing ripple effects across the air travel network. The FAA can also issue delays or airport closures due to severe weather.

Gate congestion and delays: Severe weather often causes a backlog of arriving and departing flights, leading to gate congestion. Aircraft may need to wait for available gates or be repositioned, resulting in extended wait times for passengers. These delays aren't only caused by weather. 

As operations resume, the FAA’s air traffic management can contribute to further delays, which can also be compounded by the airlines themselves, which might need to reconfigure crew schedules and adjust their flight timetables to comply with safety standards.

Tarmac and baggage delays: Once lightning strikes or heavy rain halts activity, baggage handling and aircraft servicing are also delayed. Crews cannot unload luggage or refuel planes until it’s safe to resume outdoor activity. This can create longer wait times at baggage claim areas.
