As part of my oneworld award (in business class), I have a flight on CX in Oct. from HKG-SFO. This is the last segment of my itinerary. I'm fairly sure that I won't be able to make it (the flight departs at 12:30am). There's no business class seat available on the flights later that day (2:30pm) or on the next day (12:30am and 2:30pm), for now. I was wondering if they would put me on the next flight later that day if I miss the flight by, say 10hrs (I get to the airport at 10am)? or even worse I miss the 2:30pm flight again, would they put me on the next day flight if I get to the airport after the 2:30pm flight has departed? Thanks.
