Flying off to Sicily

Last Thursday I flew off to Sicily for a long weekend. Recharging of batteries etc. It was one of the best times of the year for seeing orchids, and we saw loads of them, together with masses of other wild flowers, plus migrating birds of prey. But of course many people then criticise trips like this -- flying and all that carbon footprint. How do I justify it? The answer is, I don't really have any logical justification. It does have a carbon footprint, but since on the whole I lead a relatively low-carbon life, I suppose I feel, a little bit of indulgence is justified. Furthermore, my raison d'etre for conserving wildlife, is my own personal enjoyment of it. But while flying, I did feel that the best way of reducing the amount of carbon is to ensure that fair and realistic prices are paid for air travel. And certainly it is getting much more expensive, and there were fewer people on the plane. But it's a dilemma which is not easily solved. What do others who fly a lot feel about this?
