My travel agent booked a Z fare R/T SFO-MUC for travel in Aug.
It requires 21 adv purchase and San nite stay for $3300 all in.

However the tkt rcpt says among other things "no upgrade"

Does this mean LH is now using UA's rules on Z fares? What do I do with all my swu-1?

She checked on some other Z fares on LH and they all have the same no upgrade endorsement.
