My take. Redundancies are expensive for the senior crew. A380 crew to be kept on stand down for a long while. Quite a few 747 crew (Cpt's and FO's) will retire. Others handled via a small RIN. I can't see Qf doing a Rin from top to bottom under the contract as it's too expensive and they will go to FW to say it could potentially risk the company and its finances so better to do things another way rather than risk 30000 jobs. I think they would win that. My guess and the cheapest way, make the bottom 300 (or whatever the surplus is) LH pilots redundant at little cost and heavy crew the B787's and A330's in the short to medium term. As flying picks up and pilot numbers are needed again, redundant pilots would be brought back on in seniority order. Yes heavy crewing is more expensive but a hellava lot cheaper than redundancies at the top end by fleet or a Rin from top to bottom. Just my 2c.
