Is the Bric's Ulisse 21 inch carry-on accepted by most airlines?

Its 21 x 14.9 x 9.4 inch body fits most major US and European cabin limits. Check the specific airline, since a few budget carriers cap depth or weight lower.

How much extra space does the expansion add?

The expandable zipper adds up to about 2 inches of depth, roughly enough for a few days of extra clothing. It does not change the height or width.

Does the USB port include a battery?

No. The port is a pass-through for your own power bank, which you connect inside the case. You supply the battery.

Is the TSA lock included and can security open it?

Yes, the flush-mounted lock is TSA-approved, so agents can open and relock it without cutting the zipper.

How does it compare with a polycarbonate carry-on?

Polypropylene is more flexible and less prone to cracking than polycarbonate, but it is usually heavier. Polycarbonate feels more premium and often weighs less.

What is covered by the warranty?

Bric's covers the suitcase for 5 years against manufacturing defects. Wear from airline handling and damage to wheels or handles from misuse are typically excluded.
