I'm all for a VOLUNTARY SVT situation. If someone WANTs to go for one to three months, they should be able to bid it. And if they still can't fill the slot, they could fill trips via Xpairings or reserves (only on their R days).
If the SVT clause wasn't there, I might change my mind. I would not go to either location, but if people chose to bid the FDA's for the small cash override, so be it. It might not be good enough for me, but maybe others might think it would be worth it. The bottomline is that if people didn't think it was a good enough deal, then no one would bid it. My guess is that the Captain's seat would fill, but F/Os would be primarily new hires.
