Don't think it's actually been "sorted" yet. Yep, the ownership problem has, but UPS/FEDEX have now moved the line in the sand. Appears that now the controversial criteria is the percentage of cargo originating outside the US. They feel that if it can be shown that a preponderance of DHL (or whoever's) cargo can be shown to originate outside the US - which for DHL it does -ie: from Deutsch Post - then again the company is not "US based".
Interestingly, on same topic, few days ago all EU ministers relegated responsibility for bilateral transport agreement making to the EC. Follows and cements November European high court ruling finding all existing EU member states' bilateral agreements with non-EU states to be non-binding and in conflict with intra EU unfair trade legislation. 1 year horizon on dumping existing bilateral agreements, but handwriting on the wall. EU is going to start enforcing intra EU trade like US does with intra US commerce. If US agrees to allow EU carriers to perform cabotage in US, sure EU will agree to allow same for US carriers in EU. But that's NOT likely soon. Imagine UPS and FEDEX see this clearly, hence renewed legal pressure on DHL, and thru them Deutsch Post and the EC to water down net effect.
Interesting to watch.
Other ramification of latest EU pronouncement is any EU carrier will be able to apply to operate from any EU port to any non-EU port. BA competing with KLM AMS-ORD etc... Looks like repeat of deregulation-driven mergers in US in late '80's. Major drivers watch out. Merger mania coming your way. Hope you get a leg up on the soon-to-be-merged seniority lists!!
