Sorry to hear about your ticket... Straight trucks can be tricky to get propertly permitted, because different states have different legal limits so the registered weight in the state of registration is not going to be valid everyplace. The western states are a little easier for most permits because of the WAASHTO regional permit agreement, and more standardization across states than in the eastern half of the country.
But back to what I was going to ask... You took the load based on both the revenue available for the haul, as well as the known cost of getting there and home. You were sort of fortunate that you got routed to a major airport... but what if they had said "guess what, you get to go to Escanaba, Michigan now, too bad that only one airline flies out of there." Are you able to renegotiate your compensation in that type of situation?
