Travel from Switzerland to Venice?

Travel Info
What's the best way to get from Interlaken to Venice? Train? Fly? I want to stay 2-3 nights in the Interlaken area and then move on to Italy and work my way down. I was hoping to start in Venice when I get to Italy. Where are the international airport in Switzerland? I'll be flying in from Chicago. Thanks!

Travel Tips

Train is always the way to go in europe. It's a little over 3 hours train ride from Interlaken to Milan, and a little less than 3 hours from Milan to Venice. So, i would take train to Milan, put laggage in locker, and spend a few hours to explore Milan's Cathedral (well worth the visit), and dine in a restaurants (much nicer and more choices than restaurants in Venice), before continue heading down to Venice.

the biggest international airport that close to Interlaken is Zurich.

pay a visit to Jungfraujoch while you are at Interlaken. :)

Take the Train for one simple reason: you will see the beautiful countryside.
The train is the best way to go. If you are going to be in Switzerland for a while, sometimes it is a better deal to buy a Swiss pass, or you can buy a Euro-rail pass for the countries you are visiting. We took the Golden Rail from Interlaken to Montreaux, then a train into Chamonix France and through Mont Blanc into Northwestern Itay. It was an amazing ride, and not exactly in the direction you want to go, but the countryside is so beautiful.
