Yep it appears they are cancelling 4 to 5 flight a week out of OOL (keeping the weekend flights as normal) for the whole of MAY and combining the NRT and KIX flights into a OOL-NRT-KIX-OOL flight instead (I guess the load factors will still look good then!!!)
When I asked the checkin lady the other day at OOL about the flights in May and why a couple of my next few flights have been canceled or as JETSTAR put it 'rescheduled due to operational requirements!!!!!' (And what do I do now!!) she said and quote "Well we're not going to send a empty A330 to Japan if we can't make money are we!?!?!?!"
Oh for the good old days of scheduled airlines!!
