Alaska Airlines announced Monday it will soon be unveiling VR headsets as a trial run for first-class passengers on its Seattle-Boston and Boston-San Diego routes.

The headsets are by French-American tech company Skylights, and they will offer 3-D and 360-degree films. But 2-D movies will also be available in case passengers get motion sickness.

“These trials will help us understand how comfortable our guests are using the technology, and let our flight attendants share feedback about its impact to our in-flight service flow,” David Scotland, an Alaska Airlines rep, wrote in a press release.

Some of the 3-D films travelers can watch include “Ready Player One,” “Three Billboards Outside Ebbing, Missouri” and “Ferdinand.”

While VR has been a luxe in-flight alternative for first-class members on Emirates and XL Airways, this is the first time it will be available on a US airline. And passengers flying coach will have to settle for regular monitors.
