Bozeman Airport Sees Record Number of Passenger Visits in 2021

Bozeman Yellowstone International Airport (BZN) reported its 2021 passenger numbers, and the results are astounding. A record 1,940,191 passengers flew through the airport last year, an increase of 118.1% over COVID impacted 2020 and a 23.3% increase over the previous record of 1,573,860 set in 2019. Over 40% of passengers traveling to or from Montana traveled through BZN in 2021.

“BZN has been fortunate to see a very robust recovery in passenger traffic with record-setting passenger levels since April 2021," said Airport Director Brian Sprenger. "It is estimated the increase in passengers in 2021 generated nearly $200 million in additional economic activity for Southwest Montana compared to 2019.”

On a national basis, the Transportation Security Administration reported a 31.1% decline in passengers across 440 U.S. airports for 2021 compared to 2019.

What's driving the increase in passengers?

The addition of Southwest airlines was a significant driver in the increase. Still, nearly every airline servicing BZN added additional destinations during the year, including seasonal non-stop markets such as San Diego, Austin, and Washington DC. In addition to more flights, the average aircraft size serving BZN increased from 99 seats in 2020 to 124 in 2021.
