So in the UK there are no lounges to use if flying LH, OS or LX in Y as FTL?
I have switched my monthly flights to Germany to Germanwings anyway. As LH have been, so too have I become completely cost focused. Yes, sitting at the gate waiting rather than in a lounge is a bit of a drag, but the additional 150 euros I have in my pocket does compensate somewhat.
One thing, the 4U flights can be credited to Mile & More, and count towards M&M FTL - but what is the point? There are no benefits when flying 4U and just a handful of miles.
