I Fly,
The problem is that the particular operators I'm talking about (more than one) advertise set departure times, exactly as I showed in my original post. This is no doubt for convenience and to co-ordinate passengers, which is great. However, as I think we've deduced, this moves it into a grey area which is technically RPT, but not policed by cARSa.
What TL and I originally wanted to know was if this practice is something that carsa will catch up with eventually, or if it's something a company could include in its advertising without fear of any anal FOI's kicking their buts.
