Justice Department sues to block merger of airline IT firms

The Justice Department is suing to block Sabre Corp. from buying a rival that also provides airline booking services

In a civil lawsuit filed Tuesday, the government says Sabre pursued the $360 million deal to eliminate a competitor that has disrupted the market with more modern technology.

Sabre says it will challenge the lawsuit and is confident of winning. It says the companies offer complementary services.

Sabre is based in Southlake, Texas, and started as the reservations arm of American Airlines. It's the largest seller of services that let airlines sell flights through travel agents.

Sabre had planned to close the deal Wednesday. It was announced in November.
