You would think London having the Olympics would be a boost to helicopters companies, sightseeing flights, more tourists in London, VIP/olympic officials need flying etc, (roads gridlocked).
Every other business in London is going to benefit from the Olympics (airlines, hotels, restaurants, taxis, car hire, shops, etc)
For GA and helicopters operators it appears...alas not.
I sense the blame lies at the CAA and BHAB's feet. Imagine the government imposing nonsense restrictions on Easyjet, Ryanair, Truck companies etc - it wouldn't happen.
