When you book a private flight, there is no need to worry about printing a boarding pass. Your itinerary includes all the details required, such as the fixed-base operator location where you will be met by the flight crew. Upon arriving at the airport, you simply identify yourself to the staff at the FBO.
If you are on an international flight, you should have your passport ready for verification, and the flight crew can check your digital itinerary. Otherwise, the pilots have your details in their system and will meet you directly at the FBO. There is no need for paper copies or printed documents when flying with Amalfi Jets.
