I recently attended Dietmar Duller's two-day corporate flight attendant training course, and I would like to highly recommend his course to anybody who wants to start a career as a corporate flight attendant. Dietmar is an expert in the area of first class service and his teaching skills are orientated towards our learning experience. He encourages and motivates across all training areas and explains everything very clearly. Thank you for widening my horizons and for making me better at my job!
