If you're willing to share any of their secrets openly or by PM, I'm all (electronic) ears.

The only 'exploit' I'm aware of is that the carrier that issues the xONEx ticket appears to be free to apply their own surcharge rules to the entire thing - a weird bit of book-keeping if I ever saw one - so people used to prefer to use AA because they were still not playing the YQ/YR game. That's changed somewhat since they've officially partnered with BA/IB.
