Why Are Security Lines at Copenhagen Airport So Long in 2026?

The short answer

If you've hit a long security queue at Copenhagen Airport (CPH) in 2026, you're not imagining it. Several things are overlapping: the airport's new CT scanners are still bedding in, more bags get pulled for a manual check than travellers are used to, the checkpoint is busy during the morning and late-afternoon departure waves, and not every lane is always open. The good news is the rules are simple once you know them, and timing your arrival well makes a real difference.

What changed: the new CT scanners

CPH has moved to new-generation CT (computed tomography) scanners at security. They produce a 3D image of your bag, and the headline benefit for travellers is real:

  • Laptops, tablets and cameras stay in your bag — you no longer take electronics out.
  • Belts and watches stay on. (cph.dk)

That's confirmed on Copenhagen Airport's own security page. So why the queues? New scanning systems take time to settle in — staff are still building speed with them, and the machines are calibrated cautiously, which in practice means more bags get flagged for a manual look than you might expect. Travellers consistently report this, and it's the single biggest reason a "short" posted wait can still feel slow: the bottleneck isn't the scan, it's the bag-check table after it.

A larger-liquid allowance is the other thing CT scanners can eventually enable — but it is not active at CPH. See the liquids section below.

Liquids: still the 100ml rule (this catches people out)

Despite the new scanners, the liquids rule at CPH has not changed. Per cph.dk:

  • Containers of 100ml or less, all inside one clear, resealable ~1-litre bag (one bag per person).
  • Your liquids bag must come out of your hand baggage and go visibly in a tray — even though your electronics stay in.

This mix trips people up: "leave the laptop in, but take the liquids out" is the opposite of the old habit. Repacking at the belt — taking a laptop out only to be told to leave it in — is a big part of what slows the line. So:

  • Keep your 1-litre liquids bag accessible and put it straight in a tray.
  • Leave electronics in your bag unless a sign or staff member says otherwise.
  • Don't repack at the belt — follow the signage at your lane.

There is no larger-liquid allowance at CPH right now. Pack for 100ml and you'll never be the person stopped.

Why the wait can be longer than the posted number

We show CPH's official, timestamped security wait time — the same figure the airport publishes. It's the best live signal available, but during this transition it can understate the real door-to-airside time, because the posted number reflects the queue into the scanner, not the time spent waiting for a flagged bag to be hand-checked. On a busy morning with lots of manual checks, the difference is noticeable.

Treat the live number as a floor, not a guarantee — and on peak waves, add a buffer.

How to get through faster

  • Arrive in the right window. Security is busiest in the early-morning departure wave and the late-afternoon peak. See the best time of day to pass CPH security.
  • Liquids bag out, electronics in — and decided before you reach the tray.
  • Empty your pockets into your bag at the packing tables, not at the belt.
  • No water through the checkpoint — empty the bottle and refill airside.
  • Early flight? Make sure the checkpoint is even open yet: when does CPH security open?.
  • Flying domestic? CPH Express (fast track) lanes are available for regional Danish flights, 5 AM–9 PM.

FAQ

Why is CPH security so slow in 2026? A mix of the new CT scanners still bedding in, more bags being pulled for manual checks, peak departure waves, and not all lanes being open. The scan itself is fast; the wait is usually the manual bag-check table.

Do I still take liquids out at Copenhagen Airport? Yes. Your 100ml-or-less liquids in a clear ~1-litre bag must come out and go visibly in a tray, even though electronics now stay in your bag. Confirm at cph.dk.

Do I need to take my laptop out at CPH? No — at the new CT-scanner lanes, laptops, tablets and cameras stay in your bag. Follow the signage at your lane.

Is the official wait time accurate? It's the best live signal and we show it timestamped, but during the scanner rollout the real time to airside can run longer than the posted figure because of manual bag checks. Add a buffer at peak.
