The evening arrivals land in HKG around 7pm. HKG-SGN leaves at 915pm arrives 1055pm. SGN-HKG leaves at 6am arrives 935am. The morning HKG-US departures leave around 1130am.
1 plane-2 destinations. Of course the plane will get rotated thru back to the states, but they are only using 1 plane to service both flights by doing one during the day and one at night.
One plane from the US lands in HKG in the morning and will be used to BKK and back during the day before its return to the US. ANOTHER plane will be landing in HKG from the US in the evening (while the other is doing BKK) and will be used for the SGN round trip section overnight before it has to return to the US the next morning. So two planes that would be sitting for a long time in HKG are going to be used for two additional cities. Each plane from the US is covering an additional destination. Glaring issue with what you wrote: HKG-BKK leaves at 9am. How do you use the same airplane if it won't arrive from SGN until 935am? -35 minute turn? Plus, your own example shows the one returning to HKG at 845pm with the SGN flight leaving HKG at 915pm. 30 minute scheduled turn for the same airplane as the normal routing? Two different planes from the US to do the inter-Asian turns before they are each needed back to the US based on the schedule.
