Not familiar with married segments or amadeus at all but would like to help someone. I know there are gurus here who can answer.

Passenger buys ex tpe ticket for FRA in D class. As we know the ex-tpe tickets now are "married". He is given tpe-hkg and then hkg-FRA . Strangely, the tpe-hkg segment does not clear but the hkg-fra cleared (I thiought they only clear together)? Am I right?

Q2 - is it possible to marry a different tpe-hkg flight to hkg-fra, eg to depart tpe an hour earlier? I was saying this to warn friend that sometimes flights out of TPE are cancelled due to load factors or delayed due to whatever and this might impact the hig-fra long haul. So can he request a tpe-hkg flight an hour earlier?

Q3 - assuming that it s a "No" to Q2 above, can a passenger arrive at TPE early for flight ealier than the D class first segment and get on the TPE-HKG so that he is safe and early in HKG to fly onwards to Europe? What are chances of TPE allowing that? Can one assume that it will be allowed or only in exceptional cases?

Q4 - what if a passenger arrives in TPE too late to catch the TPE-HKG flight? Can he board a later flight (assuming that it is still possible to board the hkg-fra)?

Thank you.
