For John Glenn Columbus International Airport (CMH), FlyBuffer currently uses 5–15 min as the security planning context. The airport’s current FAA profile contains about 3,689,570 annual enplanements. A smaller passenger profile can reduce some pressure, but the range is still an estimate and can move with time of day and broader conditions.
Each vertical band is the modeled security allowance for that hour. The chart shows uncertainty instead of reducing the airport to one queue-time promise.
FlyBuffer combines historical airport-level patterns and public aviation context to keep the range useful without pretending every checkpoint is directly observed.
Use the security story together with airport context; the full departure plan still starts with your own journey time.

The 5–15 min value on this page is an airport-level planning range. Use it for the security block, then keep airport access, bags, terminal movement and gate-ready margin separate.
FlyBuffer updates the airport-level planning context when fresher inputs are available, but a modeled range is not relabeled as a live checkpoint stopwatch. Read the freshness/status language beside the estimate.
PreCheck can change checkpoint friction, but lane availability varies. FlyBuffer does not subtract a universal fixed number of minutes without lane-specific evidence.
Line length can change faster than an airport-wide model. Use the hourly range as a planning allowance and replace it with a more specific checkpoint estimate when you have one.
For John Glenn Columbus International Airport (CMH), FlyBuffer currently uses 5–15 min as the security planning context. The airport’s current FAA profile contains about 3,689,570 annual enplanements. A smaller passenger profile can reduce some pressure, but the range is still an estimate and can move with time of day and broader conditions.
The 5–15 min figure is designed for trip planning. It does not include parking, rental-car return, bag drop, the walk to the checkpoint or the trip from security to the gate. Those steps belong in the departure plan separately.
A lower typical range should not be read as a guarantee. Early peaks, heavy travel periods, a mismatch between the modeled range and your actual checkpoint, or unusual operating conditions can still increase the allowance you need.
A smaller annual passenger profile can make the typical process lighter, but one busy bank of departures can still create a meaningful queue. Keep the flight time and time-of-day pattern in the decision.
The current FAA profile records about 3,689,570 annual enplanements at CMH. A lower passenger scale can justify a smaller typical allowance than at the biggest hubs, but the current range and departure time should still decide the checkpoint buffer.
The current airport profile lists two active runways at CMH. A relatively compact airfield does not guarantee a short checkpoint queue, so FlyBuffer keeps security pressure separate from runway count and uses the hourly pattern to size the checkpoint allowance.
At CMH, the checkpoint estimate and the parking-to-terminal trip answer different questions. If your parking choice requires a shuttle, add that transfer before security. A shorter checkpoint range should not cause the planner to erase the ground-access time you still need. Official airport source →
PreCheck can reduce checkpoint friction, but FlyBuffer does not automatically subtract a fixed number of minutes without lane-specific evidence. If you have a reliable current PreCheck estimate for your checkpoint, enter it as your own security estimate in the departure planner.
Security is one block in the calculation. A shorter checkpoint allowance does not remove parking, checked bags, document processing, terminal navigation or the margin you want before boarding. Change the security input in the planner to see how much the final leave time actually moves.
Use a newer checkpoint estimate when it comes from a source you trust and is more specific to your actual departure. FlyBuffer lets you replace the security allowance without changing the rest of your trip assumptions.
CMH ranks #50 of 501 covered airports by FAA enplanements. Its 3,689,570 annual enplanements are about 4709% above the current-set median of 76,729. Passenger scale is context rather than a queue measurement, but this comparison helps explain why the same national travel-pressure signal should not be interpreted identically at every airport.
The CMH planning range is 5–15 min. DAY, roughly 71 straight-line miles away, is 5–10 min and is in a broadly similar planning band; CAK, roughly 99 straight-line miles away, is 5–10 min and is in a broadly similar planning band. The nearest covered alternative is regional rather than next door. A security-range comparison can be informative, but the extra ground journey can easily be larger than the checkpoint difference, so compare the complete door-to-gate plan.
PreCheck can change checkpoint friction, but FlyBuffer does not apply a universal fixed discount without lane-specific evidence.
Not necessarily. FlyBuffer labels modeled airport-level values as estimates and only uses live wording when a source actually supports it.
FlyBuffer labels modeled values as estimates. A value should only be described as live when a source actually supports that claim.
Use the hourly pattern to identify lower- and higher-pressure periods, then combine that allowance with the rest of your airport process.
The current planning context is 5–15 min; the full airport-arrival time also needs to include access, bags and terminal movement.
FlyBuffer does not automatically subtract a fixed PreCheck discount without lane-specific evidence.
Enter it in the departure planner so the security block uses your newer information.
Use total travel and airport process time, not security alone, when comparing airports.
