The swiss travel trade magazine Travel Inside has published the "Holiday Flights" for winter 2010/11.
The "Holiday Flights" feature almost all charter flights from Zurich, Basle, Geneva and Friedrichshafen/DE for the next winter season.
This is a nice tool to see which swiss tour operator operates charters (full charter, partcharter, seat allotments) where to and when.

The flights are part of holiday packages but many are also available as flight-only. A list of holiday destinations available as "flight-only" can be found here (german).
