Terminal Layout & Organization
Boise Airport (BOI) is intentionally simple: all flights operate from one integrated building, commonly referred to as the Main Terminal (you may also hear it called Concourse A or the BOI Terminal). There are no separate domestic/international terminals and no alliance-based zones—every carrier (including Delta, Southwest, United, Alaska, American, Spirit, Allegiant, and seasonal/charter operators) uses the same check-in hall, security checkpoint, and post-security concourse. Gates generally run A1–A22 along the single main concourse, so even if your airline changes gates, you’ll remain within the same secured area.
On this terminals page, you’ll see “Lounges” listed, but note that BOI currently has no airline-operated lounges (the Delta Sky Club closed in 2023). Instead, expect practical quiet/work areas and standard seating throughout the Main Terminal.
Navigation Between Terminals
You won’t need any inter-terminal transport at BOI—there’s only the Main Terminal. From ticketing to the far end of Concourse A is typically under 10 minutes on foot. Baggage claim, rental cars, rideshare pickup, and the parking garage are all connected via short indoor walks with escalators and elevators.
- Wayfinding tip: Follow “Gates A” signs after security; gate numbers increase along the concourse.
- If you’re meeting someone: Use the Main Terminal’s baggage claim as the easiest landmark—everything branches from there.
Traveler-Specific Tips
- Families: The Main Terminal is stroller-friendly with elevators and wide corridors. Ask at the information/help points about nursing rooms and family restrooms; give yourself extra time during peak morning departures when the single checkpoint can queue.
- Business travelers: Since there are no lounges, aim for the quieter seating pockets along Concourse A and use the terminal’s work-friendly areas. TSA PreCheck is available—if you have it, you’ll usually save time at the Main Terminal’s single security screening area.
- Travelers with disabilities: BOI’s Main Terminal is compact and accessible with elevators, ramps, and accessible restrooms. If you need wheelchair assistance, request it through your airline in advance; curb-to-gate distances are short, but staffing can vary by time of day.
- Budget travelers: You’ll find water bottle filling stations and plenty of seating; top up devices before boarding since outlets can be busiest near popular dining areas.
Practical Information
Free Wi-Fi is available throughout the Main Terminal and Concourse A and is generally reliable for email, browsing, and streaming in most seating areas. Power outlets and USB ports are scattered across gate seating—if you need guaranteed access, plug in soon after you clear security. Look for information desks/help points in the Main Terminal if you need directions, accessibility support, or ground transportation guidance (downtown Boise is typically about 15 minutes by car). BOI periodically updates spaces as it grows, so check the official BOI site/app for any construction advisories or short-term amenity relocations before you travel.
