Flyer,
You get flight pay for the whole amount and it all counts towards the productivity threshold.
Big difference here from the states, though. Flight pay makes up a relatively small percentage of your take-home, and the productivity threshold is 92 hours (in a 31 day month) so you don't actually get any very often.
Here we talk a lot more in terms of base salary than hourly rate.
Still, curious, but or otherwise what??
