Maybe BIH could use their knowledge of scheduled services and one of the leftover 61's in Newquay to rekindle a similar service given the traffic levels on the M25 and the ever increasing cost of taking the Heathrow and Gatwick express trains. It's about 60 quid and at least 90 minutes that way, not sure about the bus fare but time will certainly be about the same. Then again, now difficult is it to get a heli airborne from LHR......
