Is it okay to actually use a suction cup and stick it on the plane window (of course inside)? I'm afraid during take off and landing, the pressure drop and increase on the suction cup will cause something the window to crack or dent.

What do you think?

Assuming you talking about standard commercial planes, the cabins are pressurised to about 6000 feet if im not mistaken, so the pressure drop in the cabin isn't anything overly drastic.

Aside from that, the slightly difference of pressure due to ambient pressure drop, would more likely just make your suction cup less effective. However if you attached it mid flight, then tried to remove it during landing, it should be slightly harder to remove.

The above is my personal opinion and anyone may feel free to correct me if its wrong.

Edit: Anyhow the glass should be stronger than your suction cup and its more likely for your cup to break.

Thanks for your reply! If I'm not wrong, the cabin is pressurized to standard atmospherics pressure right?

Just stick it bro, no worries, been doin that trice already, kl-penang
And yes, the glass is tough one don't worry. U want break it. Unless i donno, U shoot it? Haha

Well standard atmospheric pressure is usually considered sea level. For most commercial jet aircraft the cabins are generally pressurised to 6000 to 8000 feet above sea level. So its slightly lower to make it easier for the aircraft structure to take the pressure difference but not low enough to cause passenger discomfort. This is the reason you get that pop-ping effect in your ears when you fly sometimes.

Edit: Anyways don't think you have to worry. They design those things with abuse loading accounted for that it would probably take quite a lot of force to break the glass.

Okay thanks guys for the reply! I think I over assumed the force of a goPro. Aha.
