Many airlines in Europe (easyjet for example) require you put in passport / ID details either when booking or checking in.

They require you to put the details in, but they are not required to check your ID when checking-in or boarding.

I’ve flown several times in Schengen where nobody checked my ID at all.

> Yeah but you need to provide proof of ID and the like if you book a flight

This was the initial thought, so seems like you agree.
