Having been up for over 24 hours, I was reluctant to try it as MSY. Reviews mentioned long waits for people on list waiting for flights.
I'm waiting for friend to arrive on a later flight. The terminal is dead and I had been sitting within eye sight of the Club elevator for 2 hours and didn't see many people going there. I finally decided to try And I got right in. There are less than 5 people here at 8pm.
I'm sure it won't work when it's busy but boarding pass scanned with no problem or issues this time when lounge was empty.
