A320baby is that 3,000 hours for a wide body/ dual aisle type.The lowest I have found is Qatar with 5,000 hours total time required for their 777 fleet. Of course The BA requirement is seniority based....but that is typical of many European and every US long haul carrier. The end result is the same that it is rare to see wide body aircraft being Comanded by guys with much less than 10,000 hours.
