It is a free program of an air transport company based on counting flown miles with the company which provides this program, its alliance partners or partner’s hotel chain and partner’s car rentals.
After the registration the passenger is given his registration number of the program which is then filled into each registration and the flown miles are automatically counted to this program. Then the flown miles can be used for e.g. free air ticket or up-grading to a higher transport class. All information about the particular program can be found at web pages of particular air transport company.
Because of great number of air transport companies we do not provide this information here.
