I agree with Racedo. This smacks of an opportunity to have some compensation from Boeing but I am sure this delay suits Virgin quite well. Its typical of the company and I would have been surprised if Boeing hadn't expected it.
This still leaves the thorny issue of their A380 order though. I agree that the only route they would use them on would be MCO. Now that the A380 production line is up and running now I wonder when VS will have to decide when they will take them... or Mr Airbus could be beating a path to Virgin demanding compensation!
Where have I heard this before?
