Travelport, owner of the Galileo and Worldspan GDSs, earned $66 million in the second quarter, down 19.5% from $82 million a year earlier.
The company said income declined due to an increase in cost of revenue.
Travelport’s revenue was up 2%, to $530 million, as a result of a $6 million increase in transaction-processing revenue in the Europe and Asia-Pacific regions. Travelport said revenue decreased in the Americas, the Middle East and Africa.
The company’s revenue from airline IT solutions increased $4 million, to $54 million.
During the first half of 2011, Travelport's income was $145 million, down 6% from $154 million. Its half-year revenue increased $5 million, to $1.06 billion.
"I am pleased to report a first-half performance in line with management expectations, which was achieved despite the impact of extraneous global events in the earlier part of the year,” Travelport CEO Gordon Wilson said in a statement.
Travelport said that the May 5 sale of Gullivers Travel Associates to Kuoni Travel Holdings allowed the company to repay $655 million in debt under its senior secured credit agreement.
