Delta Air Lines’ website and mobile applications were back in operation Thursday afternoon, after being down for at least two hours, preventing customers from booking flights or checking arrivals and departures.
The Atlanta-based carrier said it had encountered an unexpected server issue in a message to visitors to delta.com.
The problem began before 11 a.m. Eastern time, the airline said.
Kiosks at Hartsfield-Jackson International Airport and elsewhere were working during the outage, a spokesman said. Delta passengers also were advised to book a trip or manage their itinerary by calling 1-800-221-1212.
“We apologize for the inconvenience to our customers,” the carrier said in a statement.
Delta is the most frequently used carrier at Dayton International and Cincinnati/Northern Kentucky International airports.
Other airlines have suffered problems with their websites. Last month, JetBlue went offline for several hours and prompted dozens of flight delays due to a problem with a partner company.
The JetBlue outage occurred a day after United Airlines mistakenly sold tickets online for free after faulty data was put into its reservations system. The unit of United Continental Holdings Inc. honored those tickets.
In other airline news Thursday, after years of losses, American Airlines is making money by boosting revenue and cutting labor costs.
The nation’s third-largest airline is doing well enough to add dozens of new planes to its fleet, announce new flights to China, and set aside money for profit-sharing with employees.
Parent company AMR Corp. said Thursday that it earned $289 million, or 76 cents per share, in the third quarter. That’s a turnaround from a loss of $238 million, or 71 cents per share, a year earlier. AMR’s adjusted profit was a record $530 million. That figure doesn’t include bankruptcy-reorganization costs and other special items.
Revenue rose 6 percent, as passengers paid more per mile to fly. Labor costs fell 13 percent from a year ago, as the company cut jobs during its makeover under bankruptcy protection.
