Alright, we'll see if I've got this straight...
Block time is the 'expected' flight time for a leg. Block or better means that if you complete the flight in less than the expected time, you still get paid for the block. However, if you get delayed and the flight takes longer....you get paid for what you flew.
From my feeble understanding, Mesa doesn't pay more than block, even if you get delayed...
Any corrections?
