To put the lot here would take up to much room.
Basically:
Use all leave.
Reduce all pilots to the Incentive pay threshold, across all fleets.
Downtraining.
Volunteers and LWOP.
Redundancies in reverse seniority.
Redundancy paypayouts are pro-rata depending on lenght of service.
I think at the moment that redundancies would be unlikely, however it wouldn't take much more of a fall of demand and it may be possible.
Just my opinion.
