It was about 3 years ago, and I can't remember the names of the lounges, but basically it was hard to persuade them that as an Emerald I and a guest could use the best lounge there, not the one they normally allocated to people flying J on AY.

This was at the same time as they insisted on getting an open-dated paper coupon stickered before they would accept it for the flight on which I had a reservation (the only time in the whole OneWorld empire that I have had to do that in over 100 coupons).
