Lausanne to Geneva Airport
I'll be coming from Lausanne and my flight to Brazil is from Geneva, how can I get to the airport by public transport?
Just take the train from Lausanne to Geneva. Some trains are direct. If not you'll arrive in Geneva at Cornavin train station. At Cornavin you can transfer to a train that will take you to the airport.
If you want to know the schedule just have a look at this site Voyages Sncf UK. The trip takes less than an hour and there are lots of trains. Just use uppercase when searching, that is LAUSANNE and GENEVE AIRPORT.
