I think it was in the LH EA FAQ's where it was stated that JQ won't be getting any more 787's.
That must be tempered with the fact that it was in a document supposed to sell the EA, but that is what it said.
I heard a rumour just yesterday that all the 787's were going to come to QF, including the JQ ones. I don't believe it for a second, but it to is a rumour, and if Goblin's could be true, I guess this one could be also.
