Where to find crew scheduling systems for airlines?

It has been suggested that an extended version of the Airbus A380, able to hold up to 780 passengers , would enable true low-cost long-haul service. While the per-seat costs of such an aircraft would be lower than the competition, there are fewer cost savings possible in a long-haul operation and therefore a long-haul low-cost operator would find it harder to differentiate itself from a conventional airline. In particular, low-cost carriers typically fly their aircraft for more hours and flights each day, scheduling the first departure early in the morning and the last arrival late at night. However, long-haul aircraft scheduling is more determined by timezone constraints (e.g. leaving the US East Coast in the evening and arriving in Europe the following morning), and the longer flight times mean there is less scope to increase aircraft utilization by adding one or two more short flights each day.
