EES and ETIAS
It appears that EES (Entry/Exit System) for tracking all non-EU visitors' (like U.S. citizens) border crossings- replaces manual passport stamping with a digital record- went active this past October in some areas. They kind of already collect biometric data, etc. at many ports of entry. Will they now need to verify it at all "yellow roads" border crossings?
Implementation of ETIAS (European Travel Information and Authorization System) for all non-EU nationals, both those who need a visa and those who are visa-exempt, like U.S. citizens, (its a "visa-like" non-visa 
) has been delayed until the 4th qtr 2026 (Inshallah ).
Reports about EES vary from "no problem" to "what a mess" when computers go down, etc.
Has anyone experienced EES at a border crossing on a Tauck tour yet? I can't imagine what a mess implementation of ETIAS will be like, especially at CDG airport where transiting can often already be a horror show!!

I have friends who used it in Paris and Rome without issue. We will be using it in London, heading to Vienna, in a couple weeks & I will report back
An overblown non-issue in my opinion since it is being phased in. My husband’s experience was fast, efficient and friendly at København’s airport last month. It doesn’t affect me since I always travel with two passports—U. S. and Danish. It was explained to me, however, that I should not use one passport and then the other another time at “check points.” I should be consistent. Actually, I show both whenever I travel and have never experienced an issue.
A neighbor will transit through Heathrow soon. I’ll ask them how they did upon their return.
The UK is not Europe any more. They are not part of anything to do with the European system.
I was led to believe that the US does not really like dual citizens to use their other passport. I have used my British one to enter the UK a couple of times. I don’t think it’s a good idea to show two passports anywhere. I would certainly never show both coming back into the US.
ETAs may be required at Heathrow.
I have shown my passport(s) when traveling for over sixty (60)
years now and am quite astute about knowing which one to use and where. Of course I show my U S passport when re-entering the U S.
My three most often used airlines and Tauck have this information on file. I also think it is prudent to know the locations of my embassies wherever I travel.
