If Asia stopovers (eg TYO) are not permitted during pricing, does that mean that either: i) post booking or ii) post travel on 1st segment, we can change the date of the first last legs, thereby creating a stopover in TYO for example? Or will the ICN-TYO-US segments be married and effectively inseparable to allow for a stopover?
