Executive 16" Rolling Overnighter Case

Does this have a strap on the back to go over the hand of a suitcase?

Vendor confirms there is no strap on the back.

This item could really use some photos of the inside areas.

We could only get one more photo that sort of shows the inside. It’s up on the sale now, if you’d like to take a look. The only other info about the sizing is the body size and laptop pocket size being: Body Size: 14" x 16.75" x 9.5"
Laptop Pocket Size: 15.5" x 11" x 1.75"
