Swiss International Air lines（SWISS）will introduce daily non-stop flights between Beijing and Zurich．

The new service to the financial center of Switzerland is expected to start on Dec．12,2012，which marks an expansion of services for the Chinese market．In May 2008，SWISS already started direct flights to Shanghai．

The first flight to Europe has a special price of 2,680 yuan，which does not include taxes and fuel surcharges．

“I am delighted the airlines of Switzerland can contribute to growing economic ties between the two countries with new daily flights scheduled，”says SWISS CEO Harry Hohmeister．

“We are witnessing a growing demand for tourist travel in both directions．”

Apart from Shanghai and Hong Kong，Beijing will be the third Chinese destination for SWISS．

The new route marks a return to Beijing for SWISS：the airlines previously flew to the Chinese capital as late as June 2003．

SWISS will initially operate its new daily non-stop Beijing-Zurich flights with an Airbus A340-300（219 seats）and Airbu: A330-300（236 seats）air-crafts．

The modem SWISS business class offers the most suitable comforts since the seats can be adjusted into a two-meter-long bed．

Seating firmness and softness can be adjusted thanks to air cushions．

With the introduction of the new SWISS service from Beijing，the Lufthansa Group Airlines may attract more Chinese customers when traveling to Europe．

SWISS．Lufthansa and Austrian Airlines already connect five Chinese cities with Europe and beyond．

This airlines group is the leading European airlines network in the Chinese market．
