Re: Are Customs asleep at Frankfurt Airport?

I thought that everything runs through FFM because this is the largest airport in DE, but I have now requested a package with tracking and lo and behold:

Shipment information sent to FedEx

The only question is where my 3 missing air cushion letters are (sent 5 weeks ago). I have now sent 2 more air cushion letters from Shenzhen. If they don't even arrive, I suspect a thief at the post office.
Some Chinese ebay sellers say that 500 tons of letters from China are currently stored in Russia and are not processed there: http://www.focus.de/finanzen/news/wirts ... 56447.html
