Three nights · Thursday night to Sunday evening
The Long Weekend
Three nights is the sweet spot for a cabin bag and the point at which the bag stops being incidental. You need more than one change of clothes, probably a second pair of shoes, and something for whatever the reason for the weekend was.
It is also the trip where the return journey differs most from the outward one. You leave with a bag that closes easily and come back with one that does not, and the difference is usually a bottle of something and a pair of shoes worn once.
This is the trip that sells expandable cases. It is also the trip on which the expansion becomes a liability, because it is on the way home, at a gate, with a queue behind you, that the extra depth is discovered.
What people take
Drawn from what the categories on this site are actually for, not from a survey.
- A cabin case, most often a hardside spinner, chosen for the trade size printed on the listing.
- A duffel in the 32 L to 43 L range, which is where several of the listings here sit and where a soft bag is genuinely flexible.
- A travel pack with an expansion, on the theory that it will be small at the gate and larger afterwards.
- A small organizer set, four to six pieces, which at this length is the first trip where dividing the bag pays for itself.

Where it lets you down
The same bag, the same six tests, in a different order of importance.
- Stage 3The Gate Sizer
On the way out the case is closed and fits. On the way back the expansion is open, the depth has grown, and no listing anywhere states the expanded external size.
- Stage 4The Overhead Bin
A rigid case that fits a frame exactly is a case with no give at all, which is the worst possible shape to be carrying when you board last.
What this trip punishes
Every trip shape has a habit it is unkind to. These are the ones this shape finds.
- Using the expansion outbound. Once it is open it rarely closes again, and the size the bag was chosen for stops applying.
- Trusting a trade size. Twenty-one inches is a naming convention; the object is taller once the wheels are under it.
- Believing the word approved. It appears on several of the cases sized for exactly this trip and it means nothing at a gate.
- Buying shoes. Shoes are the single least compressible thing anyone brings back from a weekend.
Worth being careful about
- No airline approves a case in advance and this site prints no carrier size limits. Read the figure your carrier publishes.
- An expanded case is a different object from the case a size figure describes.
- Compression cubes make the load smaller, not lighter. The scale at the desk reads weight.
A stated size is the size of the body. Wheels, feet and an extended telescoping handle are not usually counted inside it, and the frame at a gate counts all of them.

The short version
The Long Weekend
The long weekend is the trip that most rewards measuring your own bag, because it is the trip where the bag is closest to the edge. Measure it across the wheels, closed and expanded, and take both numbers with you.
