About 11am this morning tried to gain access to the TBIT Qantas First Lounge as a BA Gold Guest List card holder on a AA domestic flight from LAX to ORD. Apologetically denied entry. Informed that to gain access the itinerary has to be connected to an incoming or outgoing international segment greater than 5 hours. Not in the argumentative mode today, but would like to see the "rules" posted on the Oneworld website so there is no confusion about access to this lounge.
