Called DC to book future reward travel, and asked for the
following
PRG-FRA: LH
FRA-BKK: LH
Stopover
BKK-ICN :OZ

The agent on the line told me that I should take more direct PRG-MUC-ICN all on LH. " PRG-FRA-BKK-ICN is not a legal routing, Sir"
Is this true?

I called DC again an hour later, but the same agent picked the phone, so I hung up. Where is our good Mansour?
