$$$$
The new CRS system is very expensive.
They would not be buying it just make our rosters better.
There have to be massive cost savings involved.
Crew productivity will surely increase = spreading ULR flying more evenly to take advantage of factoring. Getting average hours from 90 to 98 for example.
Hotel and transport costs reduced = Less layovers and/or shorter layovers. Hotel room utilization optimized so that multiple crews can use the same set of hotel rooms.
Perhaps a split of cabin crew and pilots = whereas the cabin crew do a turnaround and the pilots layover. Taking advantage of the less restrictive legalities of cabin crew.
Dubai transport costs reduced = Rostering of pilots from the same community on the same flight so that shared transport can be utilized.
I'm sure there are countless other ways that the new system can save them money. And I'm sure none of these changes will benefit us.
