I nearly missed a flight on account of good company in the lounge when I met Uncle T and iWife for the first time when we were both going to Hawaii (different routings that day) at the T5B lounge and I happened to glance at the screens - the flight was already boarding!
A mad dash to C gates and yes, I was the last one to board. I met up with T8191 and iWife again in LAX, albiet briefly as he was in the J lounge as a mere silver while I was enjoying the flounge and did not want to repeat the almost-missed-flight experience again.
I wish my passport also looked as pristine as the OP's, mine is a bit of a dog's breakfast.
