THE SHORT ANSWER
Choose a bag that fits the strictest published allowance on your itinerary without expansion. Then choose the opening and carry style that works for your route from home to hotel. More packing space is useful only if you can take it with you.
Worth considering when
Travelers choosing one main cabin bag for work trips, weekends or connections on several airlines.
Skip the purchase if
Your current bag already fits your routes and carries comfortably. Try a realistic packing rehearsal before replacing it.

Choose around the part of travel that causes trouble
| Design | Useful when | Check before buying |
|---|---|---|
| Four-wheel suitcase | You want to roll the packed bag through terminals | External wheel dimensions, handle height and lifting grip |
| Travel backpack or duffel | Your route includes stairs and carrying | Loaded comfort, packed depth and accessible documents |
| Expandable suitcase | You sometimes check a bag on the return trip | Expanded dimensions; expansion does not increase the airline allowance |
Measure the whole bag
Delta's carry-on page currently specifies a maximum of 22 × 14 × 9 inches, including handles and wheels. It also notes that partner airlines can have different restrictions and that aircraft capacity can require gate checking. Treat this as one airline's published example, not a universal cabin-bag standard.
Write down the allowances for each operating airline and fare on the actual itinerary. Compare the suitcase's exterior dimensions, including protruding parts, with each one. For a soft bag, measure it packed. A bulging front pocket still takes up space in the sizer. Leave yourself room to pack without forcing every zipper closed.
A concrete mismatch to watch for
The Away Bigger Carry-On in Stormy Teal lists exterior measurements of 22.7 × 15.4 × 9.6 inches, including handles and wheels. Those figures exceed Delta's published dimensions on all three axes. The product page also describes compatibility with most major US airlines. The measurements are the more useful basis for this particular comparison.
That does not establish what a gate agent will do on a particular flight. It establishes that this bag does not meet the cited dimensional allowance. If avoiding a forced check matters, choose dimensions within the allowance instead of relying on someone else's successful trip. The example is a sizing check, not a recommendation for or against Away's entire range.

Rehearse the parts wheels cannot solve
Pack your typical shoes, clothes, toiletries and work equipment before deciding how much volume you need. If you are comparing bags in a shop, ask whether you can test them with a representative load. Lift by the handles you will actually use, try a short carry, and check whether the trolley handle leaves your wrist at a comfortable height.
Our practical preference is to choose the opening around your routine. If you work in terminals, accessible laptop and cable storage may matter more than another internal divider. If you unpack fully at a hotel, a clamshell opening may be convenient. Check how much floor space the open bag needs and whether retrieving one item disturbs everything else.
Read the return and repair terms for the exact purchase
The cited Away color page is marked final sale and describes time-limited complimentary repair coverage followed by paid repair service. That is a useful reminder to read the selected item's terms, rather than assuming a brand-level warranty headline guarantees free replacement indefinitely.
Before paying, look for wheel, handle and zipper repair options, who pays shipping, and whether you may pack-test the bag before returning it. Save the terms supplied with your purchase. Battery-equipped luggage needs an additional check: FAA guidance distinguishes carry-on, checked baggage and trackers, and directs international travelers to their airline. Read that guidance for the exact battery and confirm how it can be removed if the bag must be checked.
