East Terminal Expansion Project

BZN Bag Claim Rendering
BOZEMAN, MT (May 15, 2024) The Gallatin Airport Authority is pleased to introduce the next chapter of growth and development at the Bozeman Yellowstone International Airport (BZN). Construction is currently underway in preparation for the largest expansion in our airport’s history, the East Terminal Expansion project (ETEP). ETEP is a multi-phase, $140-$180-million-dollar investment designed to enhance passenger and guest experience, increase capacity, and develop crucial infrastructure to support BZN’s current and future growth.

Construction will target the entire east end of the terminal from baggage claim to the parking garage entrance. The projected completion date for this expansion is 2030. Over the next six years, ETEP will unveil:
  • An enhanced A Concourse with larger hold-rooms, modern amenities, additional retail, food and beverage concessions and the capability to expand total gates from 12 to 15.
  • An expanded baggage claim area equipped with three high-capacity carousels designed to promote a seamless baggage claim process. 
  • A second security checkpoint on the east end of the terminal. 
  • A new third floor to support BZN's Airport Administration Offices. 
Phases of ETEP will require temporary infrastructure in order to maintain day-to-day airline and passenger operations alongside terminal construction. Passengers traveling this summer can expect to see various construction sites partitioned-off around the east end of the terminal as crews complete Phase 0 (PH0) or “Enabling Phase.”  Upon completion of PH0 this fall, Phase 1 (PH1) will begin later this year with demolition of the north half of the original terminal building, excavation, foundation and structural steel.

ETEP is years in the making and will offer travelers an innovative, contemporary, and efficient airport experience while still embracing the historic lodge-like character that defines our airport. This project is a critical investment to ensure BZN continues to meet the needs of our thriving community, passengers, and southwest Montana for years to come.

Additional updates will be shared as this project continues.
