Short answer: Cancellations can appear at any time, but many applicants and monitoring data suggest early morning (roughly 5–8 AM local) and mid-afternoon (2–4 PM) see more new openings. Tuesday through Thursday often have more activity than weekends. Because slots are taken within seconds, checking at “good” times alone isn’t enough—you need to either check very often or use an appointment alert service so you’re notified the moment something opens.
Why Timing Matters at All
Global Entry interview slots don’t get “released” on a fixed schedule like concert tickets. They appear when someone else cancels or when CBP adds new capacity. So “best time” really means: when do people cancel most, and when are fewer people competing for the same slot?
When Do Cancellations Tend to Show Up?
Time of day
- Early morning (5–8 AM local): People cancel the night before or first thing in the morning. Slots often reappear when the system updates and before the workday rush.
- Mid-afternoon (2–4 PM): Another common window as people change plans, miss reminders, or clear their calendars.
- Late evening: Less predictable but possible as same-day no-shows get processed.
Day of week
- Tuesday–Thursday often show more cancellations than Monday or Friday, when people are less likely to give up a slot.
- Weekends vary by center; some locations have weekend hours and see a burst of cancellations Friday evening or Saturday morning.
Patterns differ by enrollment center and season. Busy airports (e.g., JFK, LAX, MIA) have more churn simply because more people are booking and cancelling. See Global Entry Cancellation Windows: What the Data Shows for more on what the data suggests.
The Real Limitation: Slots Disappear in Seconds
Even during “peak” cancellation windows, new slots are shared by everyone using the CBP scheduler. Thousands of applicants—and automated tools—refresh or poll the system constantly. So a slot that appears at 6:02 AM can be gone by 6:03 AM. Relying only on manual checks at “good” times means you’ll miss most openings. For a practical edge, you need either:
- Very frequent manual checking (multiple times per hour), or
- An alert service that monitors the scheduler 24/7 and notifies you as soon as a slot opens at your chosen centers.
Tools like GE Finder watch the scheduler around the clock and email you when appointments become available, so you don’t have to guess the best time of day—you get notified whenever it happens.
How to Use This If You’re Checking Manually
- Pick 1–3 enrollment centers you can realistically reach.
- Check early morning (e.g., 5–8 AM) and mid-afternoon (2–4 PM) in the time zone of the center.
- Focus on Tuesday–Thursday if your center has weekday hours.
- Have your TTP account open and be ready to book immediately—no hesitation.

Frequently Asked Questions
When are the best times to check for Global Entry cancellations?
Early morning (5–8 AM local) and mid-afternoon (2–4 PM) tend to see more new slots. Tuesday through Thursday often have more cancellations than weekends.
Why do Global Entry slots disappear so fast?
When someone cancels, that slot goes back into the pool. Many people and alert services check the scheduler constantly, so openings are often taken within seconds or minutes.
Can I get alerts when a slot opens?
Yes. Appointment alert services like GE Finder monitor the official scheduler and notify you when a slot opens at your selected centers, so you don’t have to rely on timing or manual refreshes.
✅ Key Takeaway
More cancellations tend to show up in early morning and mid-afternoon, and midweek. But slots get taken in seconds, so the real advantage is either checking very often or using appointment alerts so you’re notified the moment something opens.
