As Delta’s press release says, its total revenue in the fourth quarter probably increased by 7% compared with the same period of 2017, and not by 7.5%, as previously assumed. The estimated revenue growth per unit of air transportation (carrying each available passenger seat by 1 mile) is degraded from 3.5% to 3%.
The adjustment of the revenue forecast for Delta has heightened investor concerns related to an increase in airfares and its effect on consumer demand and the financial results of carriers.
At the same time, Delta narrowed its forecast for earnings per share to 1.25-1.30 USD, which is closer to the upper boundary of the previously announced range.
Delta Air Lines is the second largest US carrier in terms of passenger turnover, with its headquarters and largest hub at Hartsfield–Jackson Atlanta International Airport in Atlanta, Georgia. As of December 2018, Delta operates a fleet of 876 aircraft manufactured by Airbus, Boeing, and McDonnell Douglas. Delta operates the largest Boeing 717, Boeing 757, Boeing 767, McDonnell Douglas MD-88, and McDonnell Douglas MD-90 fleets in the world, and the largest Airbus A330 fleet of any US airline.
