Specifications from the Samsonite web site:

Body Dimensions: 21.5" x 14.5" x 8.0"
Overall Dimensions: 22.0" x 15.0" x 8.0"

Most international airlines have a limit of 45" total dimensions and this should fit.
Many also have a 9" limit on the depth and this should fit.
The only concern is the 15" height, which might not suit a few airlines that have a limit of 14".

The weight is a bit too high for this price point.
Ideally it should weigh around 5lb.
Anything heavier should be due to more durable materials.
Not sure what type of polyester this is made of.

Comparably priced Kirkland (Costco) bag is made of Cordura/Ballistic which is heavier but stronger.
