Fuel saving
They talk about how saving 17kg of fuel per sector all adds up......
But they stand by when, for instance, the clowns in IOC completely lose the plot such as last years typhoon direct hit. Unnecessary ferrying of aircraft all over the world because there's nothing "integrated" about IOC. It's a bunch of different people making a bunch of different decisions without ever talking to each other.
So as long as they're happy to piss away a few thousand tonnes at least once a year because of IOC's woeful performance, I can't see why we'd all sit on the edge of our seats for 16 hours a few times a month. And then be told we're not worth a pay rise to boot.
