Cornish Simon -
I am no aviation professional, common sense would show that as the load factors are declining for the 'low cost carriers' at Newquay, what makes you think British Airways will pick up a route to Newquay, because at the moment if there is any chance of Newquay having a service to London it will depend on the cost (Bearing in mind B.A. is a full service airline = higher fares + ADF). Not to mention the limited slot availabilities at Heathrow itself, where B.A have more favourable, money making routes.
At the end of the day it's a tough old business, if a route won't work for one or two airlines there is a low chance of it working for others, no matter how big or small. Also PSO's are only put in place if there is a satisfactory level of usage by the public, unless you get some silly MP spending out on another 'Rolls-Royce' project.
The only possibility of seeing a regular service from Newquay to London will be when people have more wonga in their back pocket, when the economy actually goes into full swing again, at the moment it is pretty stagnant out there
