Capt Basil Brush,
An airline in Oz is restricted to 90 or less seats out of the Gold Coast on a long sector heading west, another airline offloads up to 30 pax when going to an Island off the QLD coast and it has a wet runway.
Dont think I have to name the respective carriers or routes, you should be able to work that out.
Another regional airport extended their runway for cater for the NG, they have had OG and 146, and A320 operations for a while. There would be more examples about, I don't know everything !
