I can see from that, that it is not about the fact that she works on a UK registered aircraft. Thanks Litebulbs.
It seems to be about the fact that she spends other time working in the UK, like turnaround times and training so the result of this case would NOT affect other companies with overseas staff except airlines of course.
Just from a perspective of fairness to these girls I really do think a fair outcome would be for them to be able to retire when other crew do and I am glad that the union has been able to make a case for this in whatever way is legally possible.
