Thanks @safarigal - you're on the Dec 17 Cloud cruise, right?
Good to know the charter info - I assume eventually this will appear in all of our bookings.
Our flight is at 10:00 PM - so will have to decide whether to go to the Mandarin Oriental and then back or just stay at the airport.
Several downsides to staying at the airport - at least for those flying American - their check in counters don't open until 5:30 pm, so I guess you'r stuck out in the main area til then. And then, AA doesn't have a lounge. We have Priority Pass lounge access, but that lounge has a 2 hour max time limit - although it's unclear how they kick you out after that time frame.
