This paper provides further evidence of on-going hybridization between airlines business models focusing on frequent flyer
programs (FFPs) which were viewed as a typical component within traditional concept of doing business in air services.
Confronting list of European low cost airlines which in 2005 had not implemented FFPs we found that eleven airlines within the
group analyzed started to use them after 2005. We revealed diversity among FFPs of low cost airlines which confirms a broader
role of FFPs out of pure customers loyalty issues covering also issues like product policy, price policy and policy of horizontal
cooperation. We discovered main difference between older and newer FFPs of low cost airlines in collecting and rewarding
options with regard to services of partnership airlines as well as in implementation of membership levels and purchase of credited
units. Evolutionary changes towards mature schemes of FFPs are predicted for low-cost carriers.
