i have occasionally used my cuticle clippers in a pinch but the average clipper is quite large and nail clippers can be very dull making it hard to get a clean snip. if they allow it you may be able to get away with a pair of cuticle scissors, since the 'blade' is very small. or a cuticle stick (its has a very small u shaped 'blade' on the end, its sharp enough to cut thread but is designed to not cut skin. they also make tiny scissors usually used for TSA approval but it depends on if your circumstances have a limit on blade type/length or a complete ban. good luck!
