I hadn't heard of this brand before but have used their other meet and greet service, the non-advance purchase one called DriveFly. I knew that I was definitely flying on the date I was so took the punt with the advance purchase option. All went well. It was pretty much the same service that I got last time I used them but I managed to save some money buy booking up in advance with a non cancellable rate.
