It varies massively by airport and by time of year, and you just go into “Non U.S. Citizens and Permanent Residents” (there’s almost never a “Europe” line). On airports, there are a set of U.S. airports like Los Angeles which always seem to have long queues, and a few where CBP is more prone to asking 20 questions of everyone. On times of year, visiting cities when a big convention is happening can be much slower, as can traveling near a holiday like Thanksgiving. I’ve witnessed and stood in a 3 hour queue at San Francisco and that was my #1 motivator to go get Global Entry sorted.
