The pilots will not accept any loss of conditions, as well a a meagre 3% pay rise. The Singapore basing is a big sticking point (once these things start, then where do they stop - look what happened to you guys). The eba will be voted down in a big way, and the aipa reform group will be swept to power in a landslide.
And the tech crew still slip in NY as they have to operate to CAO limits which the company cannot ask for an extension on (in fact the company and pilot will potentially be prosecuted with a resulting probable loss of the crew licence if they do break their set limits). Even putting on extra crew and making it a 4man trip still looks like coming into troubles due to delays in winter more often than not. The company have looked at it for the tech crew, but have found it will cost more than it will save.
