And worth pointing out that this is a very rare case where subcontractors are not used because it's cheaper. DHL is legally not allowed to own an airline which flies domestically within the US. Works the other way around (Fedex and UPS have EU flights) but no European airline can fly within the US. I'm quite sure that otherwise, they'd fly themselves as they own all airlines flying for them within the EU and Asia (except the ones that also fly to US).
