I fully agree with UMD and the comment he/she refers to.

@ sbm12: Also the coverage of an airline alliance is in the eye of the beholder. Apart from the mere number of destinations (Skyteam has less than StarAlliance, but significantly more than Oneworld), coverage includes also easy connections and is subjective in so far as it depends on where you typically fly.

For me, Skyteam works absolutely fine, and coverage would definitely not be an aspect under which I, in view of the number of destinations that Skyteam offers and in view of my personal travel patterns, would consider Skyteam an inferior alliance.
