Despite the current downtrend in oil prices, the bottom line continues to be hurt due to costs related to aircraft fuel. Depreciation in the Brazilian currency is also a major headwind. For 2018, Azul projects an increase in costs of R$800 million and R$900 million for currency fluctuation and fuel price, respectively. In fact, these concerns have compelled the company to trim guidance for current-year operating margin. Operating margin is anticipated to be 9% compared with the previous guidance of 9-11%.Zacks Rank & Stocks to ConsiderAzul carries a Zacks Rank #3 (Hold).A few better-ranked stocks in the Zacks Transportation sector are Spirit Airlines, Inc.
