Back when Panther was booking van loads at $2 and $2.25 and $2.50 a mile, they never offered to spread the wealth with inflated rates, it was always "at your rate". They might have been a little quicker to toss a bonus to help with deadhead or something, but not anymore. Now that freight is slow and the customers can get lower line hauls though the bidding process, Panther is booking them cheaper and aren't making as much profit per load, much less overall profit due to fewer loads. So they're gonna pinch it wherever they can. And if they can talk someone into running it for 70 cents a mile, that's more in their pocket. And if they can get some goober to deadhead 200 miles for 150 loaded for standard deadhead pay, great.
If you haven't seen it already, you'll see the FSC getting lower and lower, because the line haul bids are cheaper, and they'll make up the difference by charging the customer less for FSC. The structured FSC is about 12 or 13 cents right now, and for those running the variable rates, you'll start seeing fuel surcharges that are mostly within a penny or two of whatever the structured FSC pays.
