i think there is some confusion as to what hussar54 is actually annoyed about.
It is not that an airline states that prices start from £xxx and these fares cannot be found for a selected day...it is that for the flight/day i have selected, the price quoted (whether it be 99p or £199) is not achievable as taxes/fees are still to be added.
I'm sure the cheapest seats, quoted on the 'front page' so to speak, are available if you look hard enough, but when you give in and select a more expensive flight, what you are then quoted should be the achievable price (albeit without hold baggage/priority boarding etc).
and regardless of whether it is fuel surcharge, airport fees or taxes, they are all non optional, as hussar said, and should be in the first quoted price
