Although the FAA announced changes to on-board, in-flight cell phone usage more than a year ago, many people still don’t know that they can continue to work (or play Candy Crush) on their cell phones and tablets even after the airplane door has closed.
Passengers may now use e-book readers, play games, listen to music, and watch videos on mobile devices during take-off and landing, as long as they are in Airplane Mode. However, do keep in mind, there may be differences in the application of this allowance between the various carriers and/or plane types. Delta, United, and American Airlines do comply with this new regulation, by allowing the use of portable electronic devices below 10,000 feet on all U.S. domestic flights. Frontier passengers, on the other hand, are still required to turn off and stow their devices.
