Phones and tablets may be used in airplane mode during the flight at any time as long as they are secure. If the device transmits and does not have an airplane mode, then it may not be used. Laptops and large tablets need to be stowed away under the seat in front of you (or underneath your seat) during taxi, takeoff, and landing. Radio equipment, including remote control toys, FM/AM radio, and walkie-talkies, may not be used at any time during the flight, as well as any transmitting device that does not have an airplane mode.
Remember to put your mask on first, before assisting anyone else with theirs.
They may be behind you, as well.
You should assume that others are not/were not hygienic before you, so take caution when eating foods off of tables, seats, seat pockets, and other places onboard aircraft.
