Flights take x hours in the sky, and so would have left at `2026-10-01T09:00:00, America/Havana`, and arrives at Miami at `2026-10-01T10:25:00, America/Havana`.
Now, they have to choose, do they arrive at 10:25, and leave at 10:00? Or do they leave at 9:00, and arrive at 9:25, since only _one_ of those two timezones is changing. It is extraordinarily unlikely that they'll choose to just circle in the air for an hour so that they can just keep the same departure and arrival times.
