Use In-Flight Wireless when iPhone Airplane Mode is Enabled
You can selectively enable WiFi and Bluetooth access while your iPhone is in Airplane Mode. This is really handy since many flights are starting to have inflight wireless access, but in much of the world cellular use on airplanes is banned.
Enable the feature within Settings, then tap onto Airplane mode to enable that as usual. Next, tap to join the wireless network.
Always check with a flight attendant before attempting this, just to be sure you are in compliance with your air carrier.
