Dayton International Airport (DAY) experienced an unprecedented five-day stretch of sub-freezing temperatures from January 23rd to January 27th, 2026, causing significant disruptions to air travel operations and passenger experiences. The extreme cold led to a surge in demand for de-icing fluids, challenges with runway and taxiway maintenance, and issues with ground support equipment. Airlines were forced to proactively cancel flights, leaving hundreds of passengers stranded at the airport with limited options for shelter and food.

Why it matters

This event highlights the vulnerabilities of air travel infrastructure to prolonged periods of extreme winter weather, as well as the cascading effects that can occur across the broader transportation system. It also underscores the need for continued investment in technology, equipment, and preparedness measures to ensure airports can better withstand the impacts of climate change-driven weather events.

The details

The cold snap began unexpectedly on January 23rd, with temperatures plummeting below zero Fahrenheit overnight. The airport's immediate response focused on de-icing operations, with crews working around the clock to clear snow and ice from runways and taxiways. However, the extreme cold presented challenges for ground support equipment, as battery performance diminished and hydraulic systems experienced increased viscosity, slowing down baggage handling and aircraft servicing.
