V-Flyer

MrsPJH is being spirited off to Astana, via Frankfurt, tomorrow on a Z fare with Lufthansa. Can anyone help with guidance as how to make best use of the service? I assume she'll get lounge access ? How should I be assisting in setting expectations for a lady who has grown used to UCS...
:w
Similar Q's related to the return leg, on which she's on a Z fare with (I think) a Swiss /BMI combo via Vienna.

Any help gratefully received.
