The cost/price distinction is a disfunctional element to any, but especially to frequent travellers. Airlines should have objective comparison flight prices and they don't. They use all and any mechanism to offer the price they want to sell to <i>you</i> irrespective of any other price somebody else sees. Buy it in London? Price different to bought in Australia. Same path, same direction. Wipe cookie? Price different. Buy same carrier different partner airline? Price different. And on and on and on. There is no price there are only prices.<p>Imagine if everything we bought had this price behaviour...
