This same situation happened to me a couple years back. I was below the g-line but other junior to me got lines. I did everything I could for the line. I filed a dispute and won. 90hrs credit for the month and just had AV days over the line I should've gotten. I ended up working 1 3-day trip.

Just because you're below the g-line doesn't meant you just get what you get. Definitely dispute it and see what happens.
