"Harmonisation of Skyteam FF programs" is like "jumbo shrimp" and "military intelligence." I see it occur in the case of sponsored associate members adopting their sponsors' programs, but most of the new full members are imposing all kinds of fare class requirements, AF has imposed 25% mileage fares and such, and though DL doesn't change their rules about getting miles, they seem to keep making them more and more worthless once you do have them.

I'd really like there to be more harmonisation and more importantly simplification, but not at a "lowest common denominator" level. Get rid of the 25/50% EQM nonsense. Standardize lounge access policies. And so on.
