I would love if the developers can add the seatbelt instruction sound like “Ladies and gentlemen, the Captain has turned on the Fasten Seat Belt sign. If you haven’t already done so, please stow your carry-on luggage underneath the seat in front of you or in an overhead bin. Please take your seat and fasten your seat belt. And also make sure your seat back and folding trays are in their full upright position.
If you are seated next to an emergency exit, please read carefully the special instructions card located by your seat. If you do not wish to perform the functions described in the event of an emergency, please ask a flight attendant to reseat you.
We remind you that this is a non-smoking flight. Smoking is prohibited on the entire aircraft, including the lavatories. Tampering with, disabling or destroying the lavatory smoke detectors is prohibited by law.
If you have any questions about our flight today, please don’t hesitate to ask one of our flight attendants. Thank you.”
