There is something that is being left out of this discussion. Some carriers do not use practical miles when setting up the load. If they don't and the miles are short, that is also the same number of miles that is used to calculate the ETA. If there shorting you miles, not only are you being cheated out of money, but your also having to run harder to make up for those unaccounted for miles. I would advise you to research and learn everything you can about how to accurately determine what the loaded miles should be and then determine if your being paid and routed accurately. If not, I wouldn't waste any time arguing about it, just find a new carrier. There's absolutely no excuse for not using practical miles these days.
You are only being cheated out of money if you let yourself be. Landstar does not use practical miles and Diane and I are not cheated. We are not cheated because we base our accept/decline decision on actual miles and the money paid for the load. Note that Landstar does not pay a flat rate. They pay percentage of the load.
Example: Agent calls and offers a 1,000 mile load at $X.XX per mile, loaded miles, to the truck. We will do a quick route on the computer to determine the real miles, including deadhead, and divide that number into the truck pay to determine the true pay per mile. With that information known, we then accept or decline the load.
If we are not near a computer and mapping program when the agent calls (we do not have smart phones), we ask the agent to do the routing and calculating for us.
Again, percentage pay differs from flat rate pay. With percentage pay, the total paid for the load matters more than the exact number of miles driven. Depending on circumstances, we have accepted loads that pay $1.50 a mile, all miles, to the truck and loads that pay $37.00 per mile.
On the East Coast, we sometimes don't even think about the number of miles driven. Short runs are offered and we then think about total revenue per day; like $700 for a day on a 200 mile run, for example. That works out to $3.50 a mile but the total for the day is more important. If it was $3.50 per mile for a 100 mile run we would likely decline the load. If it was $7.00 per mile for 100 miles, we would likely accept.
Yes, it would be easier if they stated the practical miles with the load offer. But when we are making good money at a company that has freight, plays fair and treats us well, we are not going to quibble about a miles calculation method that can be easily compensated for with a few keystrokes.
There may be no excuse for not using practical miles these days but we would be foolish to leave a good company for that reason alone.
