^ When flying out of Terminal C, I usually leave the lounge about 30 minutes before boarding. In the past, I would often be through Terminal C (PreCheck) security just 15 minutes after leaving the lounge (with enough time for a brief pop into the Admirals Club there). But the PreCheck line is definitely longer nowadays-- the last few times, 30 minutes was just enough time to walk over, go through security and walk to my gate.
