Approved PEDs now may be used from gate to gate on the vast majority of worldwide Delta flights. On flights arriving to and departing from Singapore and Jamaica, all PEDs must be turned off and stowed prior to pushback and while the aircraft is below 10,000 feet. Customers will be advised onboard by flight crews of these and any other exceptions. 参考:http://www.delta.com/content/www/en_US/support/faqs/during-your-trip/personal-electronic-devices.html
