Given the number of crew who have already been through an airline going into administration of at least know someone who has, I think you'll be lucky if there is enough staff to fly the outbound sector. I'd be thinking twice about turning up for no sa or commission, statutory redundancy and maybe a basic reference you can use for your next airside pass (if you're lucky).
I agree with 2Para the crew won't want to hear a load of rubbish of pax that really are just happy their own a***s are ok. If you want to be nice to the crew just give them an easy flight home.
