Double Security Checks

That Jekka Gal · Sunday at 21:21

This has happened twice, once in Amsterdam on KLM and again, recently at Paris CDG.

I was happy to let the former go as it was during the pandemic but the second time was a few months ago.

So, the scenario is that you buy a long haul ticket via a European hub. Now, my expectation would be that, since you've already gone through security at Heathrow & are already airline, you wouldn't need to go through the whole process again 1 hour later when you land in Paris.

But I did and what was particularly gauling was the fact that I'd paid for the business lounge to while away a couple of hours in CDG but the queue for security was so long that I ended up rushing for my gate in the end.

What's the rarionale behind this nonsense?

There is little rational. I think it depends on where your onward journey is to. Flying into UK via Dubai there is a secondary check. Also flying into Australia from Bali and Thailand. They take waterbottles from you too.

That's normal at any connection - you go through security again. Deal with it.

Often you are not kept airside, and therefore it demands another security check.

Landing from BHD to LHR and flying onwards LH always requires another security check.

Flying back from Dalaman Turkey, a couple of years ago, I had THREE security checks in just that airport !

No it's not. Or if it is, it's a new normal.

Seems daft if you've just gone through the process an hour previously to get air side at LHR to have to spend an hour in a queue to to it all again at CDG.

I will deal with it. By avoiding CDG.

Maybe that's it then because I've definitely flown via Rome without additional checks in the past.

I bet this is down to the new EU Entry/Exit System being rolled out.

I've been flying around the world for 17 years with just over 100 countries under my belt. It's normal. Very rarely would you get off a plane and just walk onto another one. Nor would I want to tbh.

From Gemini:

Although the UK (including Heathrow) historically aligned with EU aviation security standards, the UK is not part of the EU's "One Stop Security" area, which typically allows travelers connecting between two EU airports (or an EU airport and certain trusted non-EU airports) to skip a re-screen.

That winds me up something rotten. I flew from Bali to KL to get a flight to LHR and you are airside, buy some water for the flight, go to the gate and you go through a security check and they take the water away from you despite buying it from the airport

Always been the case. I don’t even remember not having to redo security. I’ve even had an extra bag check before boarding at places like Dubai if using fly dubai*

Scuzi · 2025-11-10T17:57:41+0000

I recently flew from LHR to Tokyo via MUC. No security check at MUC, disembarked straight into the terminal airside a few gates down from the connecting flight.

In my mind, redoing security is the exception.

It must be something to do with Brexit and no longer being part of the One Stop Security area as per my earlier post.

I used to fly regularly on Iberia via Madrid to Asuncion and it was always as Scuzi says - disembarking straight into the terminal, airside.

Depends on the airport too. From what I can recall with CDG is that security is closer to the gate rather than right after bag drop. So regardless of how you get to the airport, you'll go through the same security as anyone else.

Yes, it certainly felt like the main security rather than a dedicated one for passengers in transit.
