So, the entire flight takes roughly 11hrs
For an 8:00pm departure, the flight duty period would start at 7:00pm. They'd have to be scheduled to block in by no later than 7:00am the next morning. Even at that, there'd be no margin for even a single-minute delay on the departure/taxi-out on the return flight.
