You could also see if the real world flight that you are intending to do has an actual stop and make a stop based on that; I understand it is common for ultra long haul flights to make a stop or technical stop for this reason and as Tom said you should comment it and if for some reason the R/W flight doesn't make that stop (which I'd be surprised if it didn't) then if you still need to make a stop (I'd say within reason) then I'd do it as long as Tom would allow it.
Not sure any of that is required, but may elevate level of fUN!
