Taking a camera on a long trip, tips?

With my experience taking a camera with me internationally/on a plane, I’ve only had trouble when traveling with it. On my trip to Guatemala, I took a disposable camera with me to save money which in the end ended up costing me more money because some of the photos got ruined when the cameras went through TSA through the x-ray thing. In Mexico and Ecuador, basically the same thing, except I lost all of my pictures, which really sucked.

So now, for my senior trip, environmental science is going to Hawaii and of course I want to take pictures, but this time I’m not taking disposable cameras. Of course I’ll have my phone with me which takes quality enough pictures, but I have an old camera that my aunt gave me a few years ago that takes film, and it takes amazing pictures but I’m concerned the same thing will happen again if it goes through the TSA x-ray machine and everything will be ruined, including my camera.

Any advice on what I should do? If it helps, the camera is specifically a Pentax ZX-10, and takes film and requires batteries. It’s a pretty quality camera, but I don’t have much of a frame of reference because I’m not an experienced photographer.

Should I just ditch the camera and trust in my cell phone?
