Why switch to airplane mode?

The “please switch your phones to airplane mode” announcement on every flight has a simple reason.

Why?

In flight, phones transmit more strongly while searching for ground cell towers. These signals can cause a light buzzing interference in the pilots' headsets and strain mobile networks on the ground. The airplane mode rule is a precaution to keep cockpit communication clear.

What can stay on in airplane mode?

• Wi-Fi: if the flight has internet, you can turn Wi-Fi on while in airplane mode.
• Bluetooth: wireless headphones are usually fine.
• Rules vary by airline; follow the crew's announcement.

SafeSkies in airplane mode

SafeSkies works in airplane mode as long as you open your flight before takeoff: the voice companion, breathing exercises, cabin sounds and offline Q&A stay with you throughout. Just open the app once at the airport, while you have internet.
