The new "principal speaker" (leader) of the Green Party, Sian Berry, was interviewed by Jon Sopel on the Politics Show today.
She refused to accept that dearer flights would hurt the poor, saying: "We do know where the growth in air travel is coming from and it's from the rich flying more often.
"There's a survey done at Stansted, it showed that the average income of the people flying out of there on cheap flights is about double the average income of the country as a whole.
"So it's people with second homes, it's people flying more unnecessarily. We're not about cutting out holidays, you know a single holiday a year for the poorest - that will still be within their price range¿ they just need to save up for their holidays and they will still be able to go.
"It won't put it completely out of their range. We do need to cut down on the capacity so that the richest do not be - are not flying like six times a year to their second homes and going skiing and going on a long-haul flight."
Jon Sopel also challenged her about her statement that she lived happily without 'an iPod, Toaster, Microwave, Dishwasher or Washing Machine'.
She was unrepentant: "It's much less hassle to not buy new things all the time, I mean the things you buy now they break down much sooner than things like my 25 year old TV which is made of wood and it's still going.
"The things you buy now, they might be more energy efficient but they embody a lot of carbon. They're coming all the way from China."
