How this ranking works
- Airlines ranked: 23 (19 for personal item, 23 for carry-on).
- Ranking rule: largest bag volume in litres first, then the higher carry-on weight limit, then airline name. Airlines with the same volume share a rank.
- Only airlines whose sizes we have verified against their official page are included. Sizes use each airline's published figures; where an airline publishes only one unit, we convert it.
- Last verification: .
