Expandable carry on luggage gives you two sizes in one bag: compressed for strict budget airlines, open for the return trip when you have more to bring home.
You pack light going out. You unzip the gusset coming home - for the jacket you bought, the wine you can't ship, the boots that didn't fit the original plan. No checked bag fee on the return. No leaving things behind.
Traveler's Choice expandable carry-ons start at $79.99. They use the same YKK® zippers and Dual Cyclone™ wheels built to pass the durability standard eight U.S. airlines use when replacing damaged bags.

Still fits the overhead bin when expanded
The first question anyone asks about an expandable carry-on: will it still fit when I actually use the expansion?
The Pagosa Carry On has two sets of dimensions worth knowing:
- Overall (compressed): 22 x 14 x 9.25" H x W x D
- Overall (expanded): 22 x 14 x 11.25" H x W x D
- Packing space (compressed): 19.25 x 13.75 x 8.75"
- Packing space (expanded): 19.25 x 13.75 x 10.75"
At 22 x 14 x 11.25" expanded, it fits within the standard overhead bin limit for most U.S. mainline carriers. Pack it compressed for strict budget airlines like Frontier. Open the gusset on Southwest, JetBlue, Alaska, or United where you have overhead bin room.
One honest note: a gate agent can flag any expanded bag that looks stuffed, even at the right dimensions. The frequent traveler fix is the same regardless of brand - expand it, don't pack past the gusset line. Use the expansion for volume, not compression.
An additional 2" of space

The gusset adds 2 inches of depth - from 9.25" to 11.25". That's a thick jacket, a pair of boots, or three days of extra clothes you didn't plan to bring.
The most common way people use it: pack tight going out to keep the bag at strict carry-on dimensions, then unzip the gusset for the return flight. You end up with more flexibility on both legs of the trip without ever paying a bag fee.
The expansion zipper is the first thing that fails on cheaper bags. The Pagosa's is built to the same standard as the main zip - it's not an afterthought. TSA-approved combination lock. Shield 98® antimicrobial lining. $109.99.
The zipper that doesn't fail when you max it out

The expansion zipper is the weakest point on most expandable carry-ons - it takes the most stress when fully packed and is usually the first component to go. The Archer Carry On uses YKK® zippers throughout, including on the expansion. Same brand used on luggage that costs three times as much.
Dual Cyclone™ wheels. TSA-approved combination lock. Ergonomic multi-stop handle with minimal wobble. $129.99.
Eight U.S. airlines - JetBlue, Southwest, Alaska, Frontier, Spirit, Allegiant, Hawaiian, JSX - use Traveler's Choice as their official replacement partner. When they damage a bag, they hand passengers a voucher for ours. Airline procurement teams make that call based on construction, not marketing.
Why Traveler's Choice?
That's Traveler's Choice running its own durability sequence - drop testing, torque, compression. The same forces airline baggage handlers apply on every flight. The bags they test are the same ones that go into airline replacement programs: when a carrier damages a passenger's bag, these eight airlines send that passenger to Traveler's Choice.
Monos expandable carry-ons start at $325. Away Flex starts at $295. Traveler's Choice expandable carry-ons start at $79.99 - and pass the same procurement standard those airlines use to vet replacement luggage. The price difference isn't a quality gap. It's a margin difference.
Traveler's Choice has been making luggage since 1984. RedDot Product Design of the Year, Luggage and Bags category, 2017 and 2019. Over 30 million customers. About 1.5 million pieces shipped every year.
