changing carrier for a segment on a OWE
just a quick question...I am currently in the middle of an OWE, and my next SYD-HKG segment is now issued for a QF flight...if now I want to take a CX flight instead, I assume I can just make a reservation with CX, go to the CX counter to check in, without re-issuing or endorsing the ticket ? and no need for any change fee ? am I correct in all these ? thanks !!
