Why do Virgin fly a 3 days a week service to Abu Dhabi when their codeshare partner flies there everyday? (and I think daily from MEL too) Does it get good loads or they just can't find another route?
I think its a bit of both. There has been various suggestion for new routes but I think LAX is the only one that has worked really well for them and its a bit risky to try new ones (I could see a SYD-LAS service for bucks weekends etc doing very well).
