Not at all, Evening Star, glad to help. Another trick that I learnt, when trying to find out who operates between two points, is to tackle it via the airports.
Most airports now have a web site and proudly display lists of all the destinations served! Sometimes you have to 'reverse engineer' the route, by going to look at the eventual destination (I started off writing ultimate destination but some clever twot would have said that the ultimate destination is the grave
) and then look 'back' to see where you could depart from or via (lousy English).
There are some sites that list all the airports and I have built up a fair collection. Smaller airfields in some countries are run by the local council and can be located through their site. In this country, Plymouth is one such example.
This site is for the USA:
USA airports
The URL that I had for European airports now seems dead.
Yahoo do a good listing of Airports by following their travel thread.
