I am convinced that much of Ruinair's success is based on the fact that modern passengers cannot do mental arithmetic. Suckered in by the tempting base price, they fail do put together the drip,drip, drip of subsequent add-ons - including the onboard catering and the surface transport costs of getting from distant airfield to destination.. My advice has always been to check what the legacy carrier charges upfront and compare it with MoL's final price.
