Boise Airport (BOI) Master Plan & Expansion Overview
As of October 2026, the Boise Airport (BOI) is engaged in a comprehensive, multi-year Master Plan update to guide infrastructure development over the next 20 years. This long-term strategy runs parallel to the airport's active capital improvement program—known as BOI Upgrade—which is modernizing facilities to accommodate the region's record passenger growth.
Updated with grounded research as of 2026-10-15.
The short answer
The Boise Airport is currently executing a two-pronged strategy: an ongoing 20-year Master Plan update (launched in 2025 and expected to continue through 2027) and a multi-year capital improvement program called BOI Upgrade. These initiatives aim to address regional growth and modernize aging infrastructure, including plans for a new Concourse A, significant runway reconstruction, and recently completed or ongoing utility and parking upgrades.
Key facts
- Master Plan Timeline
- A comprehensive 20-year Master Plan update launched in 2025 and is projected to conclude around 2027.
- Capital Improvement Program
- The 'BOI Upgrade' program is the airport's active capital improvement initiative, focusing on terminal modernization, expanded parking, and airside infrastructure.
- Concourse A Status
- Planned as a major expansion to add gates and increase capacity, Concourse A is a central feature of the long-term planning efforts and capital improvement strategy.
Understanding the Master Plan Update
The Boise Airport Master Plan is a facility-focused, long-term strategy designed to evaluate existing conditions and forecast future aviation demand over the next two decades. By aligning development with environmental, operational, and community needs, the plan ensures that future investments remain purposeful and adaptable.
- The study is a multi-year effort that began in 2025 and is anticipated to continue through 2027.
- It covers a comprehensive range of infrastructure, including airside operations (runways/taxiways), terminal capacity, landside road access, and supporting utilities.
- Public engagement is a key component, with multiple open houses scheduled throughout the planning process to gather community feedback.
BOI Upgrade: Active Capital Improvements
While the Master Plan charts the 20-year horizon, the BOI Upgrade program handles immediate and near-term infrastructure demands. This program is dedicated to meeting the needs of the traveling public through several completed and ongoing construction projects.
- Parking: Construction for the new consolidated parking and rental car facilities has been a major recent focus, with projects like the employee and public garage expansions completed.
- Runway/Airside: Significant reconstruction projects are underway to address aging infrastructure, including improvements to major runways and taxiways.
- Utilities: Critical upgrades, such as the replacement of the main electrical transformer and the construction of new fuel farm infrastructure, are being executed to support expanded operations.
Strategic Development & Concourse A
Expanding terminal capacity is a top priority to keep pace with Boise's rapid population growth. Concourse A is the centerpiece of this terminal expansion strategy, designed to add significant gate capacity to the existing facility.
- The project is being planned to handle increased passenger volume and evolving airline needs.
- The development includes integrated terminal connectivity and potential amenities, with design and implementation phases occurring as part of the broader BOI Upgrade.
- Public art and cohesive design are being integrated into the project, reflecting the city’s commitment to community-focused infrastructure.
