Hi all, first time poster (let's see how many mistakes I can make). I will be traveling LAX-NRT on Singapore Airlines in Business class with my wife. My daughter and a friend of hers will be traveling with us on the same flight, but in Economy. I know the rules state no guests for Business class, but how strict are they for the *A lounge at TBIT? That is, if I found a friendly agent at the entrance and asked nicely is there any chance of getting my daughter + friend in to the *A lounge? Or is that just a waste of time?
