I've used the service to get to Saarbruken. Very handy for that, not much use for those who actually want to go to Frankfurt. On my flight, there were a few who didn't know that it was going to twice as long to get from Hahn to Frankfurt than the flight took. They weren't impressed. If you fly Pikeyair (or any LoCo carrier for that matter) you have to do your research into their less than transparent charging system and where they will actually deliver you to!
