Would anyone like to comment as to why QF state 18 hours for the sector
Because they couldn't think of any other number between 17 and 19?
In a previous life when I did scheduling, once I'd figured things out with the AERAD charts I would add a percentage for luck to the route time.
The likes of Ryanair do this, if the route is an hour then schedule it for 1hr 15min then if one departs late one can arrive the other end on time or early and manipulate one's "on time" statistics whilst keeping the SLF happy ... if duped
