cheaper than paying to put the gas in your car. so really, nothing untoward. yesterday afternoon, in fact i was talking to some more passengers boarding one of the later germanwings flights and said to them you know have you got any fears about getting on this flight now? it s a budget flight. we know there s been an accident this morning. they say, look you know it is the way we get around europe now. it just seems so normal to us. you know it s something we have to deal with. but i don t think people are necessarily concerned about the safety record of low-cost flights, christine. i think you re right. karl penhaul, thank you for that from spain. a lufthansa spokesperson says the airline will no longer use flight 9525. lufthansa is the parent company of germanwings. it killed all 150 on board. so does low cost mean low safety? let s talk about it a little more with cnn money correspondent allison kosik. you heard what karl was saying.
