Travel with iPad
Your airline carrier may let you keep your iPad turned on if you switch to Airplane Mode—listen
for an announcement after boarding, or ask a member of the crew. Wi-Fi and Bluetooth are
turned off in Airplane Mode, so you can’t make or receive FaceTime calls or use features that
require wireless communication. You can listen to music, play games, watch videos, or use other
apps that don’t require Internet access. If your airline allows it, you can turn Wi-Fi or Bluetooth
back on, even while in Airplane Mode.
Turn on Airplane Mode. Swipe up from the bottom edge of the screen to open Control Center,
then tap . You can also turn Airplane Mode on or off in Settings. When airplane mode is on,
appears in the status bar at the top of the screen.
You can also turn Wi-Fi and Bluetooth on or off in Control Center. See Control Center on page 28.
