In my outfit we don't fly sectors that require an augmented crew by law and technically we do no augment as there is no crew bunk on board, just a seat in business class with a privacy curtain around it. That is required for flights with 4500NM or more great circle distance between departure or arrival, less if its a two sector duty. Crew composition is one captain, one senior FO (cruise captain) and one normal FO. The SFO is trained to take over as captain above FL200, but can do landings only from the right side if that is required for recency. Which can be a real issue as all of them fly MFF short and long haul and landing recency is separate for each type.
