I have flown the 727's in CGN. We used to have layovers in OSL, CPH, and WAW....even before that some MAD and VIE. The trips are built for 12 days of work with a weekend layover in CGN. Crews are US based and either deadhead or commercial to CGN. I used to take LH a lot from YVR-FRA-CGN. Also, a European company called Star air does subcontracting for us on routes we can't fly do to political reasons. The only UPS crewed 727 left in Europe, now, is the WAW trip and it is VERY senior.
