All the medical and anecdotal evidence points to 12h, 36h, 60h, etc. as being the best compromises for downroute rest periods. Unfortunately (and I do have some sympathy with the airlines here), unless you have more than one flight a day to a particular destination, it is likely that it is scheduled at the same time throughout the week, thus generating 24h, 48h, etc. slips. Not really anyone's fault and hard to see a solution.
I challenge this submission as either we are interested in flight safety through adequate rest or we operate whatever the operator needs for his schedule. Schedules can be designed to be crew sensitive to ensure adequate rest; this is a slippery slope in my opinion!
