KLM gives every passenger 1 cabin bag plus 1 small accessory, with a combined weight limit of 12kg (about 26lb). Your checked allowance depends on the fare you buy: Light fares include no checked bag, while Standard fares include 1 bag up to 23kg (51lb).
Allowances and fees change by fare, route and date, so always confirm on the KLM official site before you fly. Here is a clear guide to the 2026 rules.
KLM cabin baggage allowance
In Economy you can take one cabin bag plus one personal item (a handbag, laptop bag or small backpack).
- Cabin bag: up to 55 x 35 x 25cm (about 21.6 x 13.8 x 9.8in)
- Accessory: up to 40 x 30 x 15cm (about 15.7 x 11.8 x 5.9in)
- Combined weight: up to 12kg (26lb)
Business Class usually allows two cabin bags plus an accessory, within the same size limits.
If your hand luggage is too big or the cabin is full, KLM may check it at the gate. For US travellers, note that KLM size rules apply on the KLM-operated legs, not TSA carry-on guidance, so measure your bag to the cm figures above.
KLM checked baggage allowance
What you get in the hold depends on your Economy fare. Here is the typical 2026 picture.
| Fare type | Checked bags included | Max weight per bag | Max size (L+W+H) |
|---|---|---|---|
| Economy Light | 0 | n/a | n/a |
| Economy Standard | 1 | 23kg (51lb) | 158cm (62in) |
| Economy Flex | 1 to 2 | 23kg (51lb) | 158cm (62in) |
| Business | 2 to 3 | 32kg (70lb) | 158cm (62in) |
Standard checked bags can weigh up to 23kg (51lb). Heavier Business or Flex allowances often raise this to 32kg (70lb) per bag.
The size limit is measured as length plus width plus height combined, capped at 158cm (62in).
Flying Blue and SkyTeam perks
Your loyalty tier can add free checked baggage on top of your fare.
- Flying Blue Silver: often 1 extra bag
- Flying Blue Gold and Platinum: usually 1 to 2 extra bags and higher weight limits
- SkyTeam Elite and Elite Plus members get similar benefits
The exact allowance depends on cabin and route, so check your booking details to confirm what applies to you.
KLM excess and extra baggage fees
If you need more than your fare includes, you can add bags during booking, through Manage my Booking, or at the airport. Buying online in advance is almost always cheaper than paying at the desk.
As a rough 2026 guide:
- First extra bag: from around 40 to 75 EUR / USD online, higher at the airport
- Overweight (23 to 32kg): an added fee per bag
- Oversize (over 158cm): a separate handling charge
Tip
Sports equipment and musical instruments have their own rules. Always confirm current prices on the KLM official site, since fees vary by route and how early you pay.
If KLM delays, loses or damages your bag
Baggage problems are common, and you have rights when they happen. If KLM delays, loses or damages your luggage, you may be entitled to compensation under the Montreal Convention.
Keep your boarding pass, bag tag and a Property Irregularity Report, then save receipts for anything you buy while waiting. BagHelp can check your case, and our KLM baggage claim page explains how to start.
