The airport in Hahn referred to as Frankfurt is indeed a marketing sham made worse by the RyanAir ticket counter staff's insistence that misnaming an airport with that of a distant city is quite common. This is quite a shell game charging 12 Euro to drive airline passengers who've made every provision to get to the Frankfurt Airport on time in order to be subjected to an unexpected 1-1/2 hour bus ride to a remote cow pasture somewhere near Luxembourg. Is there any sense or reason for this? As for RyanAir a better attempt at customer service to alert passengers that their Frankfurt departure will actually take place at a remote and completely different airport. Why not simply call it the Hahn Airport? We could all live without the false advertising especially when this confusion costs extra money in rebooking fees and much lost time waiting for another flight.
