agreed, i often find viking / sentinel are the same price, would rather keep the revenue streams in the airport. as ive said ive used viking in the past and not had one issue with them.Re the discussion about Sentinel, I have no doubt they provide a good service but in my opinion we should be supporting the airport where possible. Sentinel are basically getting money for old rope. Unlike the airport, the gravel field from which they operate requires no upkeep whatsoever unlike the operations of the airport. You might well think you are protecting your pocket but could it be at the expense of other services or facilities that might benefit you at the airport?
