The rules say: 'If the rerouting results in an increase to the number of continents or extra flight segments previously charged, the ticket shall be recalculated.'
Please confirm my understanding is correct; this wording about extra flight segments is obsolete as those are no longer allowed, right?
Yes.
My recent experience.
ex-JNB DONE4 issued in Jan2016 (via online tool, CX ticketed).
1st segement in Oct2016.
After that, rerouting done by JL.
Onlly rerouting fee and tax difference and JL's handlng fee (5400JPY) were charged.
