After a series of incidents involving the Galaxy Note 7, the world’s three largest airlines by passenger traffic have officially banned the use of Samsung’s handset on its airplanes.

If you plan on flying with the device, it has to be switched off until you’re off the aircraft, according to a report from Reuters.

The news follows an official statement from the U.S. Consumer Product Safety Commission (CSPC), which urges Note 7 owners to turn the device off and refrain from using it. Samsung issue a comment of its own saying it’s working with the CSPC to ensure the initial batch of devices susceptible to the battery issue are returned.

TechnoBuffalo’s Todd Haselton documented his return experience, which was fairly painless. If you haven’t returned your device yet, you should do so immediately, even if you’re certain your handset is fine.

New shipments of the Note 7 are apparently being expedited from this week on in an effort to fulfill the influx of exchanged devices at carrier partners.

It’s been a week since Samsung issued an official recall of the Note 7, and although the company has moved swiftly to rectify the situation, the problem appears to be worsening. With fears that these devices could potentially explode mid-flight, it was only a matter of time before a ban was issued.
