Meghna Maharishi and Sean Cudahy look at airline earnings for 3Q. “Premium seems to be everything in airlines right now,” Meghna says, describing a bifurcated industry where United Airlines (UAL) and Delta Airlines (DAL) are at the top. Other airlines are catering to those wealthier travelers, adding more seats and amenities. Sean looks at headwinds that disproportionately affected American Airlines (AAL), as well as how Southwest Airlines (LUV) is remaking itself.
