Flight authorities had started to show concern regarding the use of the Note 7 by passengers while onboard ever since it was proved beyond doubt that a very rare number of the smartphones do indeed at times, explode! Cebu Pacific Air has now officially banned the use of the smartphone on their flights. Keep in mind though that you can still carry it around with you, but as long as you switch it off and don't attempt to charge it. Here's the official statement.
"In light of the recent recall of Samsung Galaxy Note 7 devices due to safety issues, Cebu Pacific (CEB) advises passengers that the usage and charging of the device are prohibited onboard all CEB and Cebgo flights beginning today, September 11, 2016, until further notice..."
"Galaxy Note 7 devices must also not be stowed in checked baggage, but may be hand-carried as long as the device is turned off at all times inside the aircraft. We sincerely hope for our passengers' full cooperation, as the safety of everyone onboard our flights remains our utmost priority,"
The US Federal Aviation Administration is speaking along the same lines and the instructions are identical to what was stated by Cebu in the above excerpt. Judging by the fact that Samsung itself has requested all users around the globe to stop using the Note 7 and go to the service centre for an exchange that will be processed as soon as possible, it might be a good idea to heed to the warnings, if you have not already.
