Instead of the airport being hell bent on trying to get a route to India launched which is a very specific market and have been trying to do this for years, with the rumour almost cropping up on an annual basis.
I think the airport should try to woah airlines like Qatar Airways and get a route to Doha launched with numerous onward connections to Aylesbury, Australia and Africa.
Looking at the Stansted thread, the new Emirates route seems to be a smash hit, and LTN could promote a Qatar route as an alternative without being in direct competition to anyone else and offering an alternative to the North London/Home Counties market. Also they have the 787-8 which could operate from the airport with ease.
They are already opening up routes at smaller airports like Gothenburg, Thessalonki, Malta, Cardiff and Malaga.
