Lufthansa lounge is nice but with flight to FRA and ZRH in the same time, it's suddenly too small really.
A330 is a really comfortable plane in LX settings.
But really tiny sandwich after reaching cruising altitude is a bit sad.
Then i wanted to buy duty free articles and Swiss Staff explained me i couldn't earn miles as i have LH Silver Card and not LX one.
Which is FALSE and i had to send all to Miles and More in Germany to obtain my miles...
Then in Zurich as usual, it's simple, quick and lounge there is so comfortable.
