To use the lounge, you must be a traveller. I think we all know what that means.
Yep, the person has to get from location A to location B, A not equal to B. That's what
travelling means. The fact that A is "xyz airport outside security" and B is "xyz airport
inside security" isn't relevant. Owing to the idiocy of the rules, one happens to need a
document to get from A to B,
even though the price of this travel is zero.
My friend A (who will chime in here if he chooses to do so). deals with the issue in this
way. He marches up to the ticket counter and says, we can do this the easy way or the
hard way. Either you issue me a gate pass, or I buy the refundable ticket. The GA issues
the gate pass.
