Would you consider an in-air concert on your next flight an amenity, or something that would make you switch airlines? Southwest Airlines is continuing its series of concerts for captive audiences, partnering with Warner Music to have the label’s artists perform mini-concerts for Southwest’s passengers.

You may not be familiar with the series, but Southwest calls its in-air concerts “Live at 35,” as in 35,000 feet of altitude. They’ve been happening since 2011, and Southwest and Warner Music Nashville recently made a deal to make their midair concert series official.
