United Continental Holdings Inc said on Friday it has scored labor deals with its flight attendants and its mechanics, whose relations with the airline were strained in recent years as the parties struggled to conclude contract talks.Flight attendants at the airline voted to approve a contract that will hike their wages between 18 percent and 31 percent in September, their union said on Friday. Some 53 percent of those who voted backed the deal.

Separately, negotiators from the airline and the International Brotherhood of Teamsters reached a labor deal in the last round of U.S. mediated talks on schedule, the parties said in a joint statement on Friday. They said they must finalize the contract language before it becomes a so-called "tentative agreement" that the carrier's 9,000 mechanics can vote to ratify or reject.
Both announcements mark major steps toward integrating United and Continental, which merged in 2010, and reducing flight cancellations.
