I haven't traveled with this case myself, but a family member used it for international travel once between the U.S. and India. I bought the lime green, 30" case and it's lovely. However, my aunt bought the same thing in yellow and it's just so sunny and beautiful, I'm exchanging mine with hers.
The case is unbelievably light for it's size! And rolling it around is a dream. :)
It got slightly scuffed on the journey. Nothing a little nail polish remover and a wet sponge couldn't handle though. Scratches are a given with hard cases so that doesn't really bother me much.
I've given this case only 4 stars because I'm yet to put it through the paces myself, so maybe I'll come back and re-write this review in time.
Also, I am a little bit disappointed that it doesn't have a separator pouch inside the case. I've seen this in other Delsey cases where the top half can be zipped closed to separate the case into two compartments. It would have been really handy.
