I just booked tickets from Isle of Man to London Heathrow with Loganair I paid £140. Great news that there are now regular timed services into London City and London Heathrow so that those who want to fly into a premium airport can and those more casual flyers can still fly with Easyjet into London Gatwick. This is the outcome I was proposing last year and suggested a fare structure of £150-£180 return would work. Interesting that some posters on here said it would never happen, I had no idea and I was just dreaming. Well the good news it did happen ! Happy flying.
