Quick answer
Unzip the expansion zipper on your personal item suitcase to instantly add 2 inches of depth, giving you about 20% more packing capacity for souvenirs or bulky items.
When to use the expansion feature
The expansion zipper is designed for the return leg of your trip when you need extra space for purchases or gifts. Using it on the outbound flight can make the bag too large to fit under the seat, so save the expansion for after you reach your destination.
A common mistake is overstuffing the expanded compartment. The bag remains carry-on compliant only when the expansion is zipped closed. Once expanded, it may exceed airline size limits for underseat storage.
Steps to expand your personal item suitcase
- Locate the expansion zipper: Find the zipper along the side or bottom of the suitcase, usually marked with an "Expand" label or a contrasting pull tab. It is separate from the main compartment zipper. Checkpoint: Make sure the zipper is fully closed before you pack for the outbound flight.
- Unzip to release the gusset: Gently pull the zipper around the entire perimeter of the suitcase. You will feel the fabric gusset unfold, adding about 2 inches of depth. Do not force it if it snags; realign the zipper track and try again. Common mistake: Unzipping only partway can create a bulge that strains the zipper. Always unzip fully.
- Pack the extra space evenly: Place soft items like clothes or a light jacket in the expanded section first. Avoid packing heavy items or shoes there, as they can distort the bag's shape and make it harder to close. Checkpoint: After packing, zip the main compartment and test that the bag still fits under a standard airline seat (typically 18 x 14 x 8 inches).
