Ms Lynne Embleton:

I recognise the importance of the regional airports but those countries that stand out with strong aviation industries are those that have put the effort into developing a hub, particularly those where the underlying population may be relatively small and they have successful industries built on the economics of hubbing. The Middle East is a prime example. It has developed an incredible aviation industry, possibly surprisingly if one thinks about the local demand, but that has been done through building very effective hubs.
