Hi Neti, the long metal tube can be separated into 3 parts, the longest part is approximately 17.5 inches. One of the metal tubes has a slight curve but as it can be split into 3 bits, it should be fine to fit in a suitcase. The black tube you can curl up. I haven't taken into account the floor attachment weight, so take that into consideration. Just to say, I have had my Henry for a few years so it's not the latest model. I don't know if they've changed the measurements for the latest models. My model is the Henry Micro (same size as normal Henrys! It might be to do with the filtration system). If you check this link, it gives you an idea of the measurements and weight
