What the Research Shows
At full 45 L expansion it is over the 22 x 14 x 9 limit — the airline fit score reflects that. Compressed, it passes.

Frequently Asked Questions
- Can a 40 L backpack be a carry-on?
- On US carriers, yes, if the pack measures within 22 x 14 x 9. Ryanair and easyJet cabin limits are smaller.
- Do I need a laptop compartment?
- If you fly with a laptop, a padded sleeve you can reach without opening the main compartment saves time at security.
