Definitely not - as @

At the United terminal (C) the TSA PreCheck line often looks very long but moves fast. I've never spent more than 15 minutes in that line. But I always allocate 30-45 minutes to clear security as EWR agents love making me wait 10-20 minutes after I walk through the metal detector so they can swab my phone.
