Corporate travel managers rated Delta Air Lines number one in this year’s Business Travel News Annual Airline Survey for the fourth consecutive year. This year’s honor marks the first time a carrier has earned top ranking four years in a row.

“Recognition from corporate travel managers for the hard work and commitment of the entire team of Delta’s 80,000 worldwide employees is important validation that we continue to lead the industry for our customers,” said Ed Bastian, Delta’s President. “Delta’s culture of hospitality, continuous improvement and unwavering dedication to be thoughtful in making travel better resonates with business travelers who depend on us to keep raising the bar on service.”

The airline ranked first among carriers in all 10 categories, with significant year-over-year gains in each and scoring particularly high in key areas of the survey, including: Value of Relationships with Account Managers and Sales Representatives; Quality of Customer Service; and Networks, Airline Partnerships and Frequencies.
