I have been using Flying J for 15 years as dedicated as I can be . On my last trip 5000 miles I had to use whatever diesel stations available .they were cheaper ,faster ,They would just turn the pump ...
I find Flying J and Pilot prices the same and in some cases cheaper than other large fuel stops in the area. I've used them and the charge card for the last few years and with few problems. With the RV lanes and large pump areas fueling is easy at either site!
