New Milestone for Passenger Traffic, Just in Time for BOI 100

As the Boise Airport enters its 100th year of operation, it is also celebrating a major milestone: Welcoming more than 5 million travelers in 2025. This marks the fourth consecutive year BOI has set a passenger record, with traffic up nearly 5 percent compared to 2024.

 A total of 5,229,399 passengers traveled through the Boise Airport in 2025, up from 4,990,885 in 2024.

 For the statistics lovers:

• Boise Airport traffic in 2025 was more than double the entire population of Idaho (5.2 million passengers compared to an estimated 2 million Idaho residents).
• From 2024 to 2025, BOI saw an increase of more than 238,000 passengers, or nearly as many people as live in Boise. 
• Over the past decade, passenger traffic through BOI has increased nearly 76 percent (2015-2025).

 BOI 100 centennial celebrations are set to begin in April 2026. Boise Airport Director Rebecca Hupp said the record setting passenger traffic illustrates how much Boise, air travel and the airport itself have evolved over the past century.

 “The Boise Airport was first established on a gravel bed along the Boise River near what is now Boise State University’s blue turf,” Hupp said. “Air service from our city started by carrying just four people at a time, and now we are welcoming over 5 million passengers a year. We’re excited to celebrate this incredible milestone that really highlights the service we provide to the region.” 

 Events and activities to celebrate the airport’s centennial are planned throughout 2026, including a public kick-off celebration on Monday, April 6, a historical exhibit in the terminal, Family Day in June and more.  

 The Boise Airport is currently served by eight airlines offering 27 nonstop destinations. New in 2026, Alaska Airlines just launched nonstop daily service to Ontario, CA and will launch seasonal nonstop service to Anchorage, Alaska this summer.
