Don't be drawn in by some of the negative comments - simply not true that service has slipped
I can only speak as I find. In my opinion, the service has slipped. Both of the long serving girls that used to be the 'front' of Signature Biggin have left, and that's a shame. They were both nice efficient and friendly people who had a can do attitude. That attitude/work ethic seems to no longer be there in this particular FBO anymore - maybe they are simply adjusting to Luton's service standards.
Each to their own though. I see you are a great advocate of the company, judging by your posting history.
Looking forward to the OP's feedback on who he used and what he thought of the service.
