I've seen this happen at least a dozen times. 76 bid pack trip but scheduled on a 75, and the other crew calls in sick. 75 reserve is called, but his pairing shows as an extra with a different pairing #. He is paid 75 rates, and I'm paid 76. Told them all to grieve it, but the company feels if the pairing # isn't in the bid pack, then it isn't a 76 trip. Thus no WB pay for those guys.
