Well, until they list it as part of the fare, I don't see how they can legally keep the YQ. When they want to start adding to the fare just the tickets from the US carriers, then they can keep it all. Just one little challenge in court and LH will be wishing they didn't start this slippery slope. Then they will have a choice, start adding the fuel surcharge as part of the fare and lose out on the revenue for award tickets, or refunding all the fuel surcharges on non-ref tickets when they are cancelled.
