Just sniffing around Swiss' new website (the one with lots of blank space at the bottom of every page ) and noticed something about their fleet...
The A340s say 'Swiss' on the side.
The A319s say 'Suisse'
The Avro RJs say 'Svizra'
The MD-11s say 'Svizzera'
What languages are used here? And do any other carriers do this? Strange!
