A few weeks ago (22 April at around 1:30PM) at the main entrance to MEL lounge they had six (6) people: 2 lounge angels (standing on either side of the entrance), plus a row of 3 people sitting at make-shift desks with computers and scanners, plus a person standing behind the 3. Every single person entering the lounge was asked to scan their BP, iPhone, etc by one of the 3 people. If not checked in already, one needed to get checked in by one of the angles.
Yesterday, I noticed they had narrowed the main entrance to MEL lounge (by using a short pillar and rope) so that only one person could enter at a time, and there were 2 angles standing on either side. I just flashed my QF card and entered without them batting an eyelid.
