DIA for a high-value "Enterprise" customer (think of a large conglomerate) is typically more costly than DIA for a low-value "Enterprise" customer (think of a family-owned travel & tour company). The large global ISP's are making more money from "enterprise" business than typical wholesale/transit services. This can support the idea that DIA can be pricier than transit.
