Kevin O'Leary was in the LAX lounge and on AC788 with his assistant (I assume) yesterday.
The best part is when the Concierge zone 0'ed him from the lounge onto the plane she decided to take me with them. The boarding gate was a zoo (the flight very late by that point) and I got a lot of "who is this ......." looks as I walked around everyone and on to the plane ahead of boarding being called - dressed in my finest ball cap, sweatshirt and shorts.
