Stierado,
I worked one year in LUX whilst having a flat in Germany, a place called Trierweiler. That is a 25-30 minute drive to the airport. If youŽd reside downtown Trier and Traffic is bad (7-9 am and pm) i could take 60 minutes from Trier to LUX. Problem is get through the city to the motorway, which usually is not a problem. (had 2 jams there in a year) There is a lot of commuting from France, Belgium and Germany into Luxembourg every day.
Luxembourg is very expensive in housing and living is also at a cost, however I liked the place. And its beautiful in summer!
WasnŽt employed by Cargolux, but met a few guys flying there, really good guys.
