Be careful what you wish for, Open Skies on the Isle of Man has led to a huge reduction in connectivity and direct air services and generally poor provision.
The IOM is well connected to Manchester (because that suits FlyBE) and Liverpool for the hospital route because it is government backed, but everything else (apart from Dublin) is poor.
Belfast twice a week, Gatwick often only once a day, Scotland twice a week, Bristol twice a week.
It's a royal pain in you live on the Island and stifles economic growth as people just can't get on and off the island and you can't attract a skill set here as they can't get home to visit family etc ..
Open skies is perfect if you're Heathrow or Gatwick, it's a disaster for small island communities ...
