I know there has been work done by agencies similar to ours in other countries. Australia and the U.K. come to mind. I know that Australia is often thought of as something worthwhile to compare ourselves to because of distances between major centres and because of our landmass.
There may be particular features in those examples where the agency might have more of a hands-on regulatory function. For example, they might be monitoring prices on more of a day-to-day basis. I believe that, in the case of both Australia and the U.K., they responded to consultations by their transport departments in terms of how they can improve competition. One aspect that I think was central to it was about access to slots at the airports and recommendations on how they can improve those for competition.
