The accolades continue to grow for Green Bay Austin Straubel International Airport (GRB), which is earning national recognition not only for service quality but also for reliability.

Earlier this year, aviation research firm Swelbar-Zhong Consultancy named Austin Straubel the 2025 Best Overall Nonhub Airport in the United States. Now, the airport has received another national nod. A new analysis by AirAdvisor ranks GRB among the most punctual small airports in the country.

The report evaluated airport reliability using U.S. Department of Transportation data from May 2024 through May 2025, focusing on chronically delayed flights and long evening delays. Austin Straubel tied for a spot among the top five most reliable regional airports nationwide. Joining Santa Barbara (California), Morgantown (West Virginia), Gillette-Campbell (Wyoming), and Durango (Colorado) as the most reliable..

Research found GRB recorded a low share of flights delayed more than 60 minutes during late afternoon and evening hours, a key factor for travelers trying to avoid missed connections or overnight disruptions. Most delays at the airport were resolved before the final flight left for the day.

AirAdvisor CEO Anton Radchenko says that “Many travelers assume small airports are more reliable, and sometimes that’s true. Reliability depends on other factors like recovery options and long term weather conditions. Flight volume also matters significantly at small airports. With fewer daily departures, a single delay or cancellation can have a ripple effect which limits rebooking options and extends travel time. ”

Radchenko noted that earlier flights generally offer better reliability at GRB, while evening delays are more likely to extend travel disruptions. “Small airports typically work best early in the day. Flights before 5 p.m. have more recovery options, while evening delays are far more likely to turn into hour-long disruptions.”
