I am surprised by the amount of negative comments in this thread. I doubt many of you have even heard of flyLAL, much less flown on the carrier.
In any case, my question is even simpler: what do you care if SkyTeam adds airlines you do not like? You simply choose not to fly on them. As has been demonstrated many times on FT, different people have different preferences, right? Even within the USA, you can find "die-hard" DL fans who never fly CO or NW and v.v. What's the fuss?! If SkyTeam can add more options for travellers then so be it - nobody's forcing you to fly them.
