Don't get me wrong there is no issue with the Highland Airways service. I just believe other airlines may not waste the oppourtunity of having an aircraft sat on the ground for most of the day and on weekends. My change of operator is a personal opinion based solely on this.
However if Highland Airways decided that they can make routes work with a J41 and utilise the aircraft more then i will be all for them to continue on the route.
I have however i am sure to have seen a Highland Airways position into Cardiff from Sumburgh performing an aircraft swap and then positioned to another location.
