What happens if you fly with airplane mode on?

This means you can't make or receive calls, send texts, or browse the internet. You can still use your phone, however: you can take photos, listen to music, play games, or compose emails/messages to send later. Basically anything that doesn't require a signal or internet.



When you activate airplane mode in 2026, your device's radio-frequency (RF) transmitters—including cellular, Wi-Fi, and Bluetooth—are suspended. Technically, this prevents your phone from "screaming" at maximum power to find a cell tower while at 35,000 feet. If thousands of phones did this simultaneously, it could potentially create electromagnetic interference with the aircraft's sensitive navigation and communication avionics. Furthermore, at high speeds, a non-airplane-mode phone would rapidly "hand off" between ground towers, which can cause network congestion on the ground. By 2026, most modern aircraft are "PED-tolerant," meaning they can handle some signals, which is why airlines allow you to re-enable Wi-Fi and Bluetooth manually once in the air to use onboard streaming or wireless headphones. However, the cellular radio must remain off to comply with FCC and FAA regulations. Using airplane mode also significantly extends your battery life during a flight since the device stops searching for a signal.

If he put it on flight mode, put it in his pocket and never took it out while you were together, it's likely he just doesn't want interruptions to his time with you. Even then, it would be more common to put it on silent, so that he could check from time to time that he could see who had been contacting them.

Personally, I think this is for psychological reasons. While the phone is on Airplane Mode, we know that there is no way for the outside world to contact us in any way shape or form. A part of our subconscious while we're sleeping could be paying attention to our phones. Waiting for that 3am phone call or text.
