I am a little confused about the open-jaw rule. Is my planned itinerary valid?

YYZ-ICN-CEB (since Asiana (OZ) is the only *A carrier that services CEB I am forced to transit in ICN)

CEB - 12 days – and will travel to HKG on my own

HKG-SIN – 2 days in SIN

SIN-YYZ



I really don't need the open jaw if the itinerary below is valid

Since OZ is the only *A carrier to service CEB is the follow route valid.

YYZ-ICN-CEB 12 days in CEB

CEB-ICN-HKG

3 days in HKG

HKG-SIN

3 days in SIN

SIN-YYZ
