United Airlines has announced that the company's pilots have voted overwhelmingly to ratify a two-year contract extension. The agreement provides significant improvements for United pilots and an extended period of stability for the company and the pilots.

"This extension provides further momentum for United as we work together with the shared purpose of making United the best airline for our employees and customers," said Oscar Munoz, president and CEO of United.

"I want to recognize the efforts of both ALPA's and United's negotiating teams. Their hard work enabled us to achieve this ratified contract extension more than a year ahead of the amendable date."

The agreement runs through January 2019 and covers United's more than 12,000 pilots
