Hi F - Go to:
http://www.flightmapping.com/
Use the interactive map and this shows who flys where from UK along with names of airlines, or search by city on the A - Z.
Larnaca airport code is LCA if you want to search BA.com for flights, etc.
The winter schedules are now running until at least March 08 for all airlines. Charters only operate full schedules in peak season, so if you ned to travel now, you will be on a regular flight, not cheapest of charters, but if you also check the Flythomson site, Flythomascook and some of the other providers, you can still getthere - just not maybe at the best time to suit you....
I've seen some reports by the way that Excel Airways are cutting their schedules - they fly to Cyprus in season - so if you book with them, make sure the flight has not been cut from their operartional lists - some of the listed flights that are cancelled are still on the booking service.
Last suggestion if you have trouble getting the exact times you want, go to :

Go to the Cyprus Airlines link and have fun arrranging a flight with a cheapie to Athens and then a hop to Larnaca with LOT, Aegean Airlines, Air Slovakia or the like - Easypeasyjet will do you London - Athens return for �100 in November, and Aegean will get you Larnaka bound for �50 each way from Athens.
Happy flying..
