As of today, Google has activated a new service for flights from the three main CH airports that allows you to search for flights. You can not book via this site but you have the details of the ticket site that allows you to book the flight.
Google will also offer a service where they will advise you if the price for the specific flight you are interested in goes down. https://www.google.ch/flights/
It seems to be similar (I have not looked at the details) to another search site called http://matrix.itasoftware.com/
The Google service was developed in Zurich in 2011 and expanded to 12 countries (including USA and FR).
