Fun fact, I rarely have to show my ID when flying in the EU. But what I don’t understand is why so many people don’t have an ID in the US. Seems like one of the very basic service governments should provide.
Did you know that Norway only introduced a national ID card in 2020? Until then if you didn't have a driver's license the only other state-issued ID option was a passport, and 10% of Norwegians don't have one. Until around 2015 or so banks would issue your bank card with a photo and your birthdate on it, and that was used as a de facto ID.
I've flown between plenty of EEA countries without ever having to show an ID. The requirement to have one in the US is incredibly stupid and only serves to make it harder for decent people to travel. It provides no actual value to safety.
So what the hell part of the EU are you talking about where they don't ask for any ID at the point where you are boarding, whatsoever?
For reference, here is Iberia's page for required ID when flying, and I've seen that this is absolutely enforced every time when checking in and boarding.
Seriously, just stop trying to use us to justify silly arguments about the USA. Yes, Europeans must show ID to travel, must absolutely show ID to vote (it would just be ridiculous if we didn’t) and getting the ID costs us money and must be renewed every 10 years (and paid for).
I fly intra-Schengen flights at least twice a year. I had to show ID sometimes before COVID but I never had to show ID after that, it actually caught my attention as anybody could have travelled in my place. I do online check-in, drop the bags, go through security, and show the boarding pass. Last time was three months ago, and once again: no ID.
From the top of my mind I can say that I travelled from/to Sweden, Denmark, Germany, Poland, Spain, Portugal in the last few years and I didn't need to present any ID to board the plane.
