I flight in two time in domestic flights.
Yup, this. Planes cost money when they sit on the ground. Round trip, including turnaround time, to their furtherest destinations is probably 16-18 hours, hence why they fit in a 3-5 hour shift for the plane outside of these times. Same with most other airlines, Aerlingus will fly their wide body planes from DUB-LHR-DUB in between US flights!
