In Tuesday's Analysts' Actions, some major airlines are getting pushed higher today by one Wall Street firm this morning. Deutsche Bank upgraded its ratings on American Airlines Group (AAL) to BUY from HOLD with a $50 price target. Similarly, the same firm raised its ratings on Delta Air Lines (DAL) to BUY from HOLD with a $50 price target. Lastly, Copa Holdings (CPA) had its ratings boosted to BUY from HOLD with a $65 price target. Carriers are largely benefitting from tumbling oil prices. Deutsche Bank analysts say jet fuel is about $0.50 under their current estimates, and 2015 and 2016 earnings forecasts for the three airlines are too conservative. Overall, the firm is bullish on American Airlines Group, Delta Air Lines, and Copa Holdings as airline credit profiles continue to get better. TheStreet's U-Jin Lee reports from New York.
