For a one-week trip, the best carry-on isn't necessarily the biggest—it's the one that gives you enough packing space while staying easy to roll and lift into an overhead bin.
The features I'd prioritize are:
-
Low empty weight (highest priority)
Aim for an empty suitcase that weighs under 7 pounds, and ideally 5–6 pounds if lifting is a concern. Every pound the suitcase weighs is one less pound available for your clothes, and a lighter bag is noticeably easier to lift into overhead bins.
-
Carry-on-friendly dimensions
For U.S. airlines, a common maximum is 22 × 14 × 9 inches (including wheels and handles). Staying close to these dimensions gives you the best chance of fitting in overhead bins.
-
Four spinner wheels
Four 360° spinner wheels reduce the effort needed to move the suitcase through airports. They let you push the bag beside you instead of constantly pulling it, which is easier on your arms and shoulders.
-
Good interior organization instead of extra pockets outside
Compression straps or panels, two main compartments, and a laundry section help fit a week's worth of clothing without adding bulk. Interior compression often makes more difference than extra exterior pockets.
-
Comfortable grab handles
Look for padded top and side handles. You'll use them every time you lift the suitcase into an overhead bin or carry it up stairs.
-
Expandable design (optional)
Expansion is handy for the trip home if you buy souvenirs, but remember that an expanded bag may exceed some airlines' carry-on limits.
Hardside vs. softside
- Hardside (polycarbonate): Better protection, often very light, and easier to wipe clean.
- Softside: Usually has exterior pockets and can be slightly more forgiving when squeezing into overhead bins.
For a one-week vacation, either works well if you're a reasonably efficient packer.
Features that are nice but not essential
- TSA-approved lock
- USB charging port (only if the battery is removable)
- AirTag/tracker pocket
- Laptop compartment (mainly for business travel)
A good target specification
- Weight: 5–6.5 lb
- Size: 22 × 14 × 9 in or smaller
- Wheels: 4 spinner wheels
- Material: Polycarbonate hardside or lightweight ballistic/nylon softside
- Interior: Compression system plus two packing compartments
If you want a week's worth of clothes without a heavy suitcase, something like this is a strong option:

Or, if keeping the suitcase as light as possible is your top priority:

If you're deciding between several styles, here's a quick rule of thumb:
- Frequent flyer: invest in durability and smooth wheels.
- Occasional traveler: prioritize low weight and good organization over premium materials.
- Need to lift the bag often: keep empty weight under 6 pounds whenever possible.
