Singapore Airlines is ranked the best among international carriers in the Best in Business Travel survey again this year, two years in a row.
For our second annual survey, Fortune partnered with Travel + Leisure to ask readers about their habits and brand preferences while traveling for work. They named their favorite airlines and rated them using a variety of criteria, including customer service, frequent flier programs, in-flight class experience, food and entertainment options, and airport lounges.
Here’s what sets Singapore Airlines apart from the rest:
• Many of its 15,000 menus are tailored to the carrier’s route map. First- and business-class fliers leaving from London, for example, can have a full English breakfast.
• KrisFlyer Spree, the airline’s new online mall, means passengers have nearly 2,000 brands—from Paul Smith to Muji—at their fingertips.
• A new premium economy class will debut on U.S. flights by the end of 2015, with custom leather seats, foldout leg rests, and 13.3-inch HD screens.
• A new customer-experience management system will soon give crew members access to passengers’ travel preferences.
