Look, I don't like it either, specially when you arrive at the same time at the same hotel like the UPS guys, I always finde them a bit snobby, but it is according to the agreement, WE can not fly within the US because its the same country, same for UPS, they can not go from CGN to MUC, but they can of course go from CGN to WAW, GVA, LIS, etc. It is what it is.
The race to the bottom already started in DHL some time ago.
If you go to BSL, which is technically in France, you will meet a FedEx 757, coming down from CDG. Bottom line: We go nowhere, they go everywhere!
