If you work for Swiss and your base is the Euroairport Basel-Mulhouse-Freiburg, you can also live in Germany, for example Weil am Rhein which is approximately 15 minutes by car from the airport. A two-room-appartement is about 400,00 including utilities and the neighbourhood is great.
About the language: the former Crossair only asked their flight attendants to be fluent in english and either german, french or italian. Swiss requires fluency in english, german and french.
@ Mrs. Float Jockey: when you are a EU-Passport-Holder and fluent in german, why donīt you go for Lufthansa? They are looking for more than 1000 new flight attendants in 2003 and the work conditions are excellent. Greetings from Munich, Sandrina
