The benefits of reduced separation standards due to ADS-B across the country outside radar coverage isn't something that is readily apparent to operators.
They are flying closer and level changes can be accommodated far more readily than was possible using pre-ADS-B procedural separation.
Flex tracks & UPRs are often vastly different from the published route structure which just tend to be fairly similar to Great Circle tracks, so the benefits of flex tracks & UPRs to operators have been significant.
