Bozeman Yellowstone International Airport (BZN) sits in Belgrade, Montana, about 8 miles northwest of downtown Bozeman and a scenic drive from Big Sky Resort, Montana State University, and the north and west entrances to Yellowstone National Park. As Montana's busiest airport, it serves a fast-growing mix of business travelers, second-home owners, and outdoor enthusiasts flying in and out of the Gallatin Valley — many of whom also travel internationally and want to skip the CBP line when they land back in the U.S. The Global Entry enrollment center serving BZN travelers isn't in the main terminal — it's at the Airport Operations/U.S. Customs building at 550 Wings Way, Belgrade, MT 59714, just north of the airport's control tower. Travelers from Belgrade, Bozeman, Livingston, Big Sky, and even Butte and Helena typically route their interview through this location.
Use Snapslot to find appointments and skip the line
No available appointments at Bozeman?
Hundreds of savvy travelers have skipped the long wait by using tools like Snapslot, which sends real-time SMS alerts when cancellations open up new appointment slots. Bozeman's enrollment center has historically run on a limited, periodic schedule rather than daily walk-in hours, which means openings can be scarce and unpredictable — Snapslot can help you lock in an interview far sooner than checking manually.
Knowing the Global Entry Application Process
Submit Your Application The first step to obtaining Global Entry is to submit an online application through the Trusted Traveler Programs (TTP) website. Ensure you provide accurate information and complete all required fields. The application includes personal information, passport details, employment history, and travel history.
Await Conditional Approval After submitting your application, CBP will review it to determine your eligibility for Global Entry. If your application is conditionally approved, you'll receive a notification via your TTP account. This approval does not guarantee enrollment but indicates that you have met the initial criteria.
Schedule Your Interview This is the tough part. Once conditionally approved, log in to your TTP account to schedule your Global Entry interview. Bozeman's enrollment center has a track record of hosting interviews as periodic events — sometimes just a few days every few months — rather than year-round daily slots. Because of that, appointment windows fill up fast when they do open. Snapslot can help you secure a slot the moment one appears, including cancellations.
Attend Your Interview Show up prepared with your passport, conditional approval letter, and other required documents.
Await Final Approval After your interview, final approval typically arrives within a few days, though some have reported it taking months.
Preparing for your interview
Getting ready for your interview is crucial. Here's what you may need (refer to official notes for a complete list):
A valid passport and another form of ID (e.g., driver's license).
Conditional approval letter from the Trusted Traveler Program.
A list of countries you've visited in the past five years (if asked). The agent may ask you the reason for the visit, how long you went for, etc. It's mostly a honesty check, but be prepared to answer those questions.
Pro tip: Dress professionally, and be prepared to answer questions about your travel habits and purpose for applying.
Getting to your appointment
Parking at Bozeman Yellowstone International Airport
BZN offers on-site short-term and long-term parking directly in front of the terminal — Premium Lot A, Economy Lot B, and Premium Covered Lot C. Rates generally run from about $2 per 30 minutes up to a daily maximum, with Economy Lot B the cheapest option for a quick interview trip and Premium Covered Lot C the priciest but closest to the doors. First-hour parking is typically free in Lot A and the One Hour Free Lot, which can work well if your interview is quick. Off-site, third-party lots near the airport tend to undercut on-site rates for longer stays. Because the Airport Operations/U.S. Customs building sits away from the main terminal near the tower, give yourself extra time to park and walk or drive over — this isn't the same lot you'd use for a flight.
Getting to Bozeman Yellowstone International Airport for your appointment
BZN doesn't have a dedicated public transit line or train service to the terminal. The Gallatin Valley bus line (Streamline) connects Bozeman, Belgrade, Montana State University, and Bridger Bowl, but service to the airport itself is limited, so most travelers rely on driving, rideshare, or a taxi.
Rideshare (Uber and Lyft) and local taxi companies operate at BZN, and several hotel shuttles serve nearby Belgrade and Bozeman properties. If you're coming from Big Sky, Livingston, Helena, or Butte, book a shuttle or car service in advance — options from those towns are limited and don't run on demand.
If you're coming from nearby communities like Livingston or Big Sky, driving or booking a rideshare or private shuttle in advance is generally more reliable than counting on public transit.
No available appointments?
If you're struggling to find an open slot at Bozeman, try these options:
Check nearby Montana ports: CBP has historically rotated Global Entry enrollment events across Bozeman, Glacier Park International Airport (Kalispell), and Great Falls International Airport. If Bozeman is booked out, one of these may open sooner.
Manual refreshing: Keep checking the TTP site frequently — slots often appear without warning and are taken within minutes.
Set up alerts: Snapslot can do the work for you, sending SMS alerts as soon as a new slot opens at Bozeman or nearby Montana enrollment centers.
Good to know:
The enrollment center is at 550 Wings Way, Belgrade, MT — the Airport Operations/U.S. Customs building just north of the control tower, not inside the main passenger terminal. Some more recent airport postings list the same building at 662 Wings Way, so double-check the address CBP provides in your appointment confirmation before you go.
Bozeman's Global Entry interviews have been run as periodic enrollment events (sometimes just a couple of days at a time) rather than a permanent daily-hours office, based on CBP's public announcements. Confirm current scheduling availability in your TTP account, since this can change.
BZN is in the middle of an East Terminal Expansion project, and some airport functions (including recent board meetings) have temporarily relocated to the Airport Operations building due to construction — a good reason to confirm your exact interview location and allow extra time for construction-related detours.
The Bozeman CBP office can be reached directly for scheduling or logistics questions at (406) 388-2144.
