There are other money diverters as well. Even Delta has apparently got a claim on a large sum, USD 200m, relating to their JV, described by the Delta CEO here :

now it's not particularly apparent what this is for, but if it's "related to their JV" it doesn't sound like payment for any goods received, which in any event would never be allowed to get up to that level anyway. The statement there that it's an amount "the airlines agreed earlier this year" is a bit opaque about it. JVs do not normally require one party to pay the other large sums. Is this just some further part of a tax management money-go-round ?
