I recently bought a Jakob Winter JW 62017 Stone Violin Case (having previously bought a Jakob Winter JW 52017 Violin Case). I have to say that I am very pleased with both! These are well-made cases, nicely finished, robust and a perfect fit for my violins.
The weight and dimensions in particular are ideal for travel and I certainly don't foresee any hand luggage problems when flying. The handle grip is comfortable, and the sturdy shoulder straps are a bonus.
(The Stone finish is especially suited to the addition of stickers for those so inclined!) As we say in Scotland, "Braw!"
