I agree with most everyone here, that it is much too soon to talk about the overall status of the project based of the first few months of operations.
That said, these rumors are persistant, and I know of some truth to them:
"Virgin however reported early on that they were quite pleased with the performance of their aircraft."
'Performance' perhaps, but not reliability. As previously mentioned, Airbus made garauntees that the aircraft would be 99+% dispatch reliable. This was probably in part to match the 777's reliability and disprove the ascertion that twins are more reliable that quads. So far, I've heard 97-98% figures.
" IIRC range also turned out better than predicted as a result of this."
I've heard just the opposite. I have heard the aircraft performs better than expected, however, that only makes up for the fact it is overweight. Owing to either the weight issue or an engine issue, range is below advertised.
I think its important to remeber what Gerardo stated: that Airbus is incorporating a more light-weight wing on the aircraft, which would hopefully clear up these issues.
". . .or is this this another case of quoting opinions on another forum as fact."
I know I'm probably going to piss off just about everyone here, but if you are referring to the Orders forum, I would take their "opinion" over this forum's "facts" anyday. Sorry, that's just how I feel.
