Actually I don't see that clause as being any big deal, there is a similar clause in the Virgin Blue EBA. And I don't see a lot of domestic routes that would warrant a 777 working it anyway. Remember with fuel prices the way they are there won't be much incentive to ferry a 2/3 empty plane around with the higher number of crew required as well.
Maybe it's time to put our efforts towards finding the flexibility and fair t&cs balance we all want. No I don't want to see a reduction in pay or conditions. But I am happy to allow changes that provide a fair outcome for both company and crew. I don't believe it's necessary for anyone to take a pay cut in order for the company to benefit from increased flexibility. They also need to know that we are people and have fatigue limits which do put a cap on the sheer number of hours that can be worked in a given work period. That's just part and parcel of using human labour.
