taking a later flight
I am currently booking a flight from TPE-HKG, that is the start of a ticket that I am looking on Orbitz. The flight is 7am in the morning, with a one day layover in HK, then flying to Europe, via a different airline. If i ended up missing (or don't take) the 7am flight, but still want to go to HK later that day, what will be my options (I am in business class):
1) Will Cathay re-book me on a later flight for that day, so long as I pay the change fees?
2) Can they do this over the phone via their customer service, vs. having to show up at the airport?
3) Do I have to tell them before my 7am flight take off that I am not taking that flight, and that I want to switch to another flight later that day?
4) Does it matter that the ticket was purchased from Orbitz?
Thanks in advance for your advice.
