On a recent, pivotal episode of Succession, the most jaw-dropping thing that happened was not the major plot twist—it was that nearly all of the passengers aboard the company jet were making calls from the airplane the entire time they were flying.

Granted, the inner circle of the Roy clan are not known for following the rules (and their private plane probably made its own rules), but still, shouldn’t they have been on airplane mode for the safety of everyone on board? And can you even make calls from the middle of the Atlantic? By this point, we’ve all been trained to think that keeping cellular service on during a flight is more dangerous than ordering that third Bloody Mary on an empty stomach. So what does airplane mode do? Here’s what air travelers need to know about airplane or flight mode and what happens if you don’t switch it on when the plane takes off.
