Air Southwest was primarily set up to operate LGW-PLH-NQY and therefore protect PLH airport. I have no knowledge of the airlines finances but wonder whether Sutton Harbour, who lets face it are a property company, might be thinking is it all worth it with Flybe attacking the jewel in the Air Southwest crown and the current economic climate?
I worked for Westward Airways back in 1970 so would love Plymouth to have a burgeoning future but sadly doubt there will ever be anything other than a handful of flights from there.
