Delta Air Lines and Amadeus have expanded their commercial relationship to enable the sale of Economy Comfort, Delta's premium economy seats offering more legroom, through Amadeus' global distribution system (GDS). The expanded long-term agreement provides more choices for Delta customers and travel agents to access the popular Economy Comfort seating when booking travel via Amadeus.

"Delta is encouraged by the direction of the technology innovation at Amadeus, and this partnership demonstrates that Delta is listening to its valued corporate and agency partners by broadening the availability of our popular Economy Comfort seating," said Wayne Aaron, vice president, marketing programs and distribution strategy at Delta. "It's part of the more than $3 billion we're investing to improve the travel experience of our customers at all points of their journey."

As part of the new agreement, Amadeus also will work with Delta on initiatives to further personalize and enhance the customer experience as Delta continues to transform the distribution of its products and services. Amadeus also will continue to distribute Delta's branded fares as well as its Economy Comfort premium seats.

Economy Comfort features three to four inches of additional leg room across Delta's fleet of two-class aircraft as well as giving passengers priority boarding. On long-haul international flights, the seats also have up to 50 percent more recline than standard economy class seats and customers receive complimentary beer, wine and cocktails. Economy Comfort is available on all Delta mainline aircraft and more than 250 two-class regional jets.
