I fully agree with
brunos. Moreover, while
creber mentions a pretty bad experience of ADP having the great idea of merging acces no1 with the regular EU line, I have experienced some even "greater" genius who had had the fantastic idea to merge the acces no1 line with the NON EU line!! 2E, early morning with all those flights arriving from the US, I'll let you imagine how happy I was!

(PS: I do find France in general and CDG in particular to be the absolute worst in Europe for the respect of EU immigration lines. There is regularly absolutely no enforcement/difference between the two or only one or other available to some category of passengers. It regularly totally infuriates me!
