The Global Entry enrollment center at Ontario International Airport sits inside the International Terminal, in the arrivals area, in Ontario, California. It is a natural choice for travelers across the Inland Empire, including Rancho Cucamonga, Upland, Fontana, Chino, and Pomona, and it draws applicants from as far as Riverside and San Bernardino who would rather avoid the drive and traffic into LAX.
The enrollment center is located in the International Terminal, Arrivals only, which is separate from the domestic terminals most travelers use for a typical flight. You can preview the airport layout on Google Maps or check the arrivals curb on Google Street View. Ontario also publishes its own parking and transportation page worth checking before you head over.
Appointments are scheduled through the Trusted Traveler Programs site, so confirm your current window on ttp.dhs.gov rather than assuming a fixed schedule.
No available appointments at Ontario International Airport?
An empty calendar at Ontario is common rather than a sign anything is wrong. This is one of only a handful of Global Entry enrollment centers in Southern California, so it draws applicants from a wide stretch of the Inland Empire, and most open slots come from someone else's cancellation rather than a new block being released. Instead of reloading the government site by hand throughout the day, many travelers use Snapslot to get a text the moment a cancellation opens up here.
Knowing the Global Entry application process
Whether this is your first application or a renewal, the steps are the same:
- Submit your application: create an account on the Trusted Traveler Programs site, complete the Global Entry application, and pay the non-refundable fee.
- Await conditional approval: CBP reviews your application and background. Once conditionally approved, you can schedule an interview.
- Schedule your interview: usually the hardest step, since Ontario serves such a wide region. Snapslot alerts as soon as you are conditionally approved can help you land a cancellation well before the next open date on the calendar.
- Attend your interview: arrive with your documents for a short conversation with a CBP officer in the International Terminal.
- Await final approval: most applicants hear back shortly after the interview, with cards arriving by mail within a couple of weeks.
Preparing for your interview
This location is specific about documentation. Bring a valid, unexpired passport book; passport cards are not accepted here. Bring your driver's license, and if your residence differs from what is on it, bring proof of current residency such as a utility bill or lease. Lawful permanent residents need their green card with the machine-readable zone. If you have ever been arrested, bring certified court documents showing the disposition, regardless of how long ago or the outcome; a simple name-search document is not accepted. Applicants interviewing for the APEC program should bring proof of current business involvement with APEC-approved countries.
Be ready to talk through your travel history over the last five years. The interview doubles as an honesty check, comparing what you wrote on your application against your history and how you answer in person, so answer plainly rather than guessing at dates. Dressing reasonably professionally, while not required, tends to make the appointment go more smoothly.
Skip the manual refresh. Snapslot watches Ontario Airport's Global Entry calendar and texts you the moment a cancellation opens.
Getting to your appointment
Ontario is a manageable, mid-sized airport, but the International Terminal sits apart from the domestic side, so it is worth knowing where you are headed before you arrive.
Parking at Ontario International Airport
There is a dedicated lot for international arrival travelers at the International Arrivals Terminal, and all Ontario Airport lots are cashless, so plan to pay electronically. Since you are heading in for an interview rather than a flight, the closer international-terminal parking is usually the more convenient choice over the general terminal lots.
Taking public transit to Ontario International Airport
OmniTrans runs a free ONT Connect shuttle between the Metrolink station in Rancho Cucamonga and the airport, and riders with a Metrolink ticket can use the shuttle at no additional cost. There is also a transfer option via Omnitrans Route 81 from the East Ontario Metrolink Station to the airport's rental-car facility, with a shuttle from there to the terminals. This makes Ontario workable by rail and shuttle for travelers coming from along the Metrolink lines. If you are coming from Rancho Cucamonga, Upland, Fontana, or Chino directly, a rideshare straight to the International Terminal is often more straightforward than coordinating the shuttle connections, particularly for an early appointment. Since walk-ins are not accepted, arriving late is not really an option.
No available appointments?
If Ontario's calendar looks empty, you have a few real options beyond waiting:
- Enrollment on Arrival: if you are flying internationally into a participating airport, you may be able to complete your interview upon arrival instead of booking a separate appointment. Check the current list of participating airports against your itinerary.
- Refresh the TTP site yourself: some travelers still check the official scheduler multiple times a day, since cancellations at a regional Southern California airport can appear at almost any hour.
- Set up Snapslot alerts: instead of watching the scheduler yourself, get a text the instant this location has an opening.
Remember the two things that make this location a little different: the enrollment center is in the International Terminal specifically, arrivals only, not the domestic terminals, and the documentation requirements here are stricter than at many locations, particularly around arrest history and proof of residency. Bring every document listed above, and note that each additional family member needs a scheduled appointment of their own.
