I’m sure if they send you a CR letter you’ll still have time to ask for LWOP and I’m pretty confident they’d grant it given that your LWOP request is a truck load cheaper than the 26 weeks they’re going to pay you under CR.
If you’re thinking LWOP in the hope that someone senior gets CR’d, and therefore you’ll come back off LWOP to fly before the CR pilot is re-employed, then you need to keep in mind that if enough pilots take LWOP then no one gets CR’d. Then as a LWOP pilot you’ll come back when they need you- which will effectively be the same time as they would have re-recruited you if you were CR’d anyway. Except now you didn’t get 6 months CR payout.
