Many of the low cost airlines will show you what proportion of the ticket price are taxes when you book on their web sites.
What they don't, and probably won't do, is tell you how much is the Government levied security charge, airport levied passenger handling charge and landing fee.
Whilst the Government charge is fixed, the airport charges vary according to what the airline has been able to negotiate with the airport operator - this is confidential material that only the airport taxi drivers would be able to tell you.
