I think a strong case can be made that the company knowingly misrepresented trips to be worth more than they actually were, allowing pilots to pick these trips up, and adjusting the credit on their pay sheet.

Contractual or not; misrepresenting pay for over 3 weeks now is negligent at best, and perhaps deceit and fraud on the other end of the spectrum.

I would still believe any pilot who swapped out or picked up a trip prior to the union email going out has a strong NCC case.
