Underseat Flat

For rows where the space is shallow, not narrow

Longer and wider, but 6 cm shorter than the 18. On aircraft where a bar or a box sits under the seat, height is the number that fails first.

01Measured

2 sets of numbers

Taken off the finished piece, laid flat, with nothing clipped to the outside. Handles and hardware are inside every figure.

  • Empty, unexpanded

    42 × 28 × 14 cm

    422814CENTIMETRES

  • Filled, as listed

    42 × 29 × 15 cm

    422915CENTIMETRES

    Loaded with

    • 1 hooded sweatshirt
    • 3 T-shirts
    • 1 pair of trousers
    • 1 flat toiletry pouch
    • 1 folded rain shell

A loaded figure is only published when we can also publish what was inside it. Where you do not see a loaded row, it is because that record does not exist yet — not because the bag stays the same size when it is full.

02Check it against your own limit

Put your three numbers in

We subtract them from the figures above and show the gap on every edge. No verdict, no promise — the arithmetic and nothing else.

Size Ledger

Enter the limit you have been given

Take the three numbers your carrier publishes for your ticket and type them in. We hold no carrier data of our own, so nothing here can go out of date.

Published limit

We compare numbers, not policies. Airlines change limits and measure differently at the gate.

Arithmetic result

A-03 · Underseat Flat

Waiting for three numbers

Nothing is compared until you type a limit. We do not guess, and we do not store a list of anyone else’s rules.

03Specification

What it is made of

Materials
  • 420D high-tenacity nylon shell
  • Polyurethane inner coating
  • Recycled felt base panel
Hardware
Nylon coil zippers with moulded pulls, acetal buckles
Water-resistant shell

Sprayed with 2 L of water at 20 °C from 30 cm for 3 minutes, closed and held at 45°. Zippers, seams and the base panel are not sealed and are not part of the test.

This is a resistance rating under the stated test, not a waterproof rating.

Suggested load

Rated to 8 kg. Damage caused by carrying more than the rated load is wear, not a fault — see the product safety page.

Details

  • Wide flat profile that slides in on its long side
  • Full-width document sleeve in the lid
  • Compression strap across the interior
  • Low-profile side handle, 1.5 cm of added width
