ZRH (Zurich) Airport (also Switz.) seems better organized:
To get into the secured area you swipe your bp [or show it to the agent]--there are 4 scanned lanes, one for business/fc/priority and the other 3 for "others". Several feet away is security, there is bc/fc/priority section and "others", but most of the time there is no lane checker. [Once when the bc/fc/priority lane got "long" there were 5 people waiting they sent pax upstairs where there was another security station.]
Most of the time pp check has nearly no lines; in the summer there are more flights to the USA (these leave from E gates), ALL at nearly the same time...hence longer lines.
