Coca-Cola North America has extended its supply deal with Southwest Airlines.

The unit comfirmed late last week that it will continue as the beverage provider for the airline for an additional three years.

Under the terms of the deal, the beverage maker supplies soft drinks including Coke, Diet Coke, Sprite and Sprite Zero, Seagram's mixers, and Minute Maid juices on all Southwest Airlines flights.

"We are proud to extend our relationship with Southwest Airlines. We have partnered together to refresh employees of Southwest Airlines and Southwest Airlines customers for more than 35 years," said Jim Terry, Coca-Cola North America vice president national sales. "We look forward to continuing this great alliance."

Scott Halfmann, Southwest Airlines' vice president of provisioning, added: "We are pleased to continue our long-term partnership with Coca-Cola. It's great to work with a partner who understands our corporate culture and operating philosophy which focuses on providing outstanding customer service and running an efficient airline operation."
