Lounge access on "both ends", when flying domestic.

Well, that would be DACH-based FTLs.

As more and more LH Business-lounges are enhanced, FTLs do (almost) only get access to lounges while in the LH group home market (DACH), with less and less airports outside of it offering lounge access. Heck, they even enhanced it away in BSL last year (and now enhanced all LX flights from there, as it seems no one wanted to fly from it anymore..)

I remember the "good old times", when I, as a little FTL back then, flying LX, even had lounge access in quite a few international destinations. YUL, IST etc. - all gone now. (seems a few outstations still have access, like Mumbai..)
