Because they showed up on time for work, and the inability to work was not their fault. If we have a power outage and I'm unable to work because our systems are down, I get paid. Yes, I know the whole exempt employee thing, but I believe that our hourly people would get paid in this situation since the failure was not theirs.
Cheers.
But FA's are paid for the time they're flying (gate to gate, I guess??), so no flying = no pay. Are you proposing a change to this system?
