Is it okay to use my DSLR Nikon on a airplane?

So i love taking photos (even if its a couple) and videos as well.
i'm wanting to do sort of a music video with my DSLR like parts of being in the airplane (like showing out the window) and then the rest for my trip.

I'm going to be on southwest.

or when will it be "okay" to use it? I know when they show you the safety video and when they mention to turn off all electronics is when not to use it but is any other time good? Anyone use their DSLR on a plane by southwest? Any trouble?

this is probably the last and only trip i'll have for a long time and so thats why i'm asking cause i'd love to make a music video showing my trip.

honest and helpful answers.

please and thanks

You are required to turn off all electronics during takeoff and landing while you are below 10, 000 feet. Once above 10, 000 they will inform you it is okay to use electronic devices. At that time you are free to use your camera.

Just remember to use some common courtesy. That is since you are in an enclosed space, avoid using your flash or any extra lighting. Also, don't get too "wild" in making your music video where you would be disturbing other passengers.
