For my MBA thesis I’m doing research on the usage of frequent flyer programs. I’m mostly focusing on Europe but off course I cannot go around the major US programs. I find it hard to find information about the FF programs. Information I’m looking for: - How many miles are collected in the program each year - How many miles are used each year (how many on trips/upgrades/other things/…) I find bits and pieces of information spread over the internet but not something I can safely integrate as trustworthy data. Thanks for helping me/pointing me to a good source!
