Lifetime NW club...never lent out...too afraid that the one time they would ask to see i.d. it would be to the person I gave card to...and I'm sure they would cancel me and not refund any of lifetime money.
I did however try to "leave" my 62 year old dad in club. We were coming back from a trip and going home to different cities, I needed to run to the gate to catch an earlier flight...I wasn't too smart (now I would know what to do), but then I came in, showed my card to desk, and then told my dad I would call him later, then I tried to leave...the desk clerk saw this and said, "I'm sorry sir, you have to stay with your guest". Well, I took off out the other door and I guess she came up to my dad and kicked his butt out!!
He had to wait 3 hours for his flight...I'm sure the cup of coffee he would have had would have "broke the bank" for the world club...but I do know the rules and this was against them...
Next time...I wouldn't have made it so obvious that I needed to leave and it would not have been a problem.
