# What PreCheck actually saves, and when it doesn't

> PreCheck saves up to 35 minutes at a busy hub hour and nothing at a quiet airport. What it can't touch: bag drop, the walk, the gate cutoff.

PreCheck saves up to about 35 minutes at a big airport's worst hour, about 16 minutes on an average daytime hour at a big airport, and close to nothing at a small one. It does nothing for bag drop, the walk to your gate or the gate cutoff. At $85 or less for five years, it pays for itself if you leave from a busy airport a few times a year, and I wouldn't bother for one trip a year from a small field.

Many reviews of PreCheck are there to sell you a credit card that pays for it, so they quote the best case. Here's the arithmetic for the ordinary one.

## The saving depends on the hour

The TSA says about 99% of PreCheck passengers wait less than 10 minutes. I can't test that claim: the public counts I use don't split out PreCheck lanes. If you take it at face value, then your saving is the gap between the top of the usual band and 10 minutes.

| Usual band for that hour | Allow without PreCheck | Allow with PreCheck | Saving, at most |
|---|---|---|---|
| Under 10 min | 10 min | 10 min | 0 min |
| 10 to 20 min | 20 min | 10 min | 10 min |
| 20 to 30 min | 30 min | 10 min | 20 min |
| 30+ min | 45 min | 10 min | 35 min |

That's a planning calculation. On a day the line runs short, you save less.

Then the question becomes how often you're in each row. Across the 30 airports with the busiest checkpoints, from 5 AM to 8:59 PM, 59% of airport-hours are in the top two bands. Across all 426 airports, it's 4%. Averaged over those daytime hours, the top-of-band allowance comes to about 26 minutes at the big 30 and about 14 across the country, so the typical planning saving is about 16 minutes at a big airport and 4 at the average one.

Take a Thursday at 6 AM at O'Hare, where the usual band is 30+. PreCheck could plausibly take 35 minutes off your morning. The same flight from Burbank, where the band never goes above 10 to 20, saves you 10 at the very most. The [worst hours table](/articles/leaving/worst-hours-at-airport-security) shows where your airport sits.

## What it can't touch

In the [chain of steps before a flight](/articles/leaving/when-to-leave-for-the-airport), security is one link. If you check a bag, the airline's cutoff is still 45 to 60 minutes before departure, and PreCheck doesn't move it. The walk to Concourse E at Atlanta is the same length. The gate cutoff stays where it is.

So the person who gains most is someone with no checked bag, leaving at a busy hour. With a bag at 6 AM, you still have to clear the counter, and if that line is long, the time you saved at security goes to waiting there instead.

It doesn't help after you land, either. Coming home from abroad, you go through passport control, and [getting from the gate to the curb](/articles/landing/how-long-from-landing-to-curb) is untouched.

## The shoe change narrowed the gap

Keeping your shoes on used to be half the appeal. DHS ended the shoes-off rule at domestic airports in July 2025, so everyone now keeps them on. PreCheck still lets you leave electronics and 3-1-1 liquids in your bag, and keep your belt and light jacket on. That's a smaller difference than it was, and a shorter line is now most of what you're buying.

The release promised shorter waits for everyone, and didn't give a measurement. If standard lanes got faster, PreCheck's saving shrank by the same amount.

## The cost

As of November 7, 2026, a new five-year membership costs $79.75 to $85, depending on which enrollment provider you use, and online renewal starts at $58.75. Global Entry costs $120, also for five years, and includes PreCheck. If you leave the country even once every couple of years, it's the better buy, given the extra $40 and the faster way back in.

Three small print items. Your Known Traveler Number has to be in the airline reservation, and the PreCheck indicator has to show on your boarding pass, or the lane won't take you. The TSA says no individual is guaranteed expedited screening. And its FAQ notes that a PreCheck lane isn't always available, in which case you may be sent to a standard lane.

## None of this measures a PreCheck lane

The bands describe an airport as a whole, on a normal week, and the table leaves out holiday weeks, when the difference may be larger. Airport-hours aren't passengers either: a busy hour holds far more people than a quiet one, so passengers meet the top bands more often than the percentages suggest.

Typical security times are estimated from public passenger-throughput data. Not affiliated with any airport, airline or government agency.

> Skycap doesn't know whether you have PreCheck, so the leave-by uses the time you set for being at the airport. Pick a shorter one in "Be at the airport" for this flight or in Settings for all of them, and the leave-by follows. [How the leave-by works](/app/features#before)
