Detailed Luggage Guidelines
Here is the full breakdown of size sizer dimensions, weight caps, and carry-on/checked bag policies.
| Luggage Type | Maximum Size (Inches) | Maximum Size (Metric) | Weight Cap | Standard Cost |
|---|---|---|---|---|
| Personal Item | 16.1 x 11 x 5.9 in | 41 x 28 x 15 cm | No strict limit | FREE (Fits under seat) |
| Carry-On Bag | 22 x 14.1 x 9 in | 56 x 36 x 23 cm | 15 lbs (7 kg) | Free carry-on for all passengers, including domestic flights |
| 1st Checked Bag | Max 55 linear inches | Max 140 linear cm | Max 50 lbs | $0 USD |
Qantas has a smaller checked bag sizer (140 cm linear / 55") than US major carriers (158 cm / 62"). Double check your large checked bags, as standard 30-inch suitcases may exceed the Qantas linear limits.
Best bag selection: Use a medium 25-inch checked spinner (like Travelpro Maxlite 5 Medium) which stays safely under the 140 cm limit.

Exceeding either sizer dimensions or weight caps will result in extra charges at check-in or boarding gates.
