Yeah, I think its completely unfair actually to post 30 listings of one aircraft so that is why I made the suggestion. Will see what happens with it though.
If I see pages and pages of one type of aircraft by one airline, I don't bother to even look through the rest as its too much to go through. That's why I think a limit of 5 will be good for each airline and maybe about 10 or 15 for the brokers in the public worlds.
