United Airlines revises guidance for double digit jump in PRASM; Continental Airlines down

North and South American carriers' shares were mostly down on Wednesday (17-Mar-2010), despite the Dow (+0.5%) reaching a 17-month intra-day high during trading. The rise came after the US Labor Department reported a seasonally adjusted 0.6% year-on-year decline in the producer price index for finished goods in Feb-2010, after an unrevised 1.4% rise in Jan-2010. The news helped to reduce the chance of higher interest rates and inflation.
