Virgin America claims the top spot among U.S. carriers in the Best in Business Travel survey again this year.

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’s keeping Virgin America ahead of the competition:

• Two words: live streaming. Satellite wi-fi recently launched on 10 A320s, with more to come. Internet speeds are eight to 10 times faster than any other in-flight system.

• Plush full-size pillows and duvets have spruced up an already standout first-class cabin, complementing the white leather seats and lumbar massagers.

• Its Elevate loyalty program has a “no blackout date” policy—and is a boon for those looking to book on major holidays and during peak travel periods.

• Virgin is the only U.S. airline with on-demand food ordering. Just press a button on the seat-back touch screen, settle in, and wait for your artisanal cheese plate to arrive.
