If we don't take a final sector?
I purchased RTW from Seoul startiing ICN-HKG-DXB .......
The last sector will be NRT-ICN to complete the RTW.
If I do not take this last flight and finish the RTW in JAPAN, is there any penalty not to complete RTW?
Also, I might not take one flight at the middle of RTW and use ground transportation, does it require re-issuing the ticket because of re-routing?
Thanks in advance.
