bungeewoman,
welcome to flyertalk. It would be helpful if you reveal where you are traveling from.

Austrian does not have a first class service, and both LH & OS fly only C/Y cabins to ZAG.
FRA has plenty of lounges (access depends on status and booking class)
VIE has some lounges (2 x Biz lounges, 2 x SEN/*G lounges - especially SEN on Pier A can be pretty crowded during rush hours)
ZAG has 1 *G/Biz lounge (rather tiny and not really what I would call a Biz class lounge).
Cheers
