Planning a trip with the Royal Dutch Airlines? Whether you are flying hop-skip-jump across Europe or taking a long-haul flight to Asia or the Americas, understanding the luggage rules is essential.
KLM is known for excellent service, but they are also known for strict adherence to their baggage policies. Getting caught with an overweight bag at the gate can start your trip off with a hefty fine.
At A Glance: KLM Baggage Allowance Summary
Before we dive into the fine print, here is the quick reference guide for your allowance based on ticket class.
| Ticket Class | Carry-On Bags | Personal Item | Max Combined Weight (Cabin) | Checked Bags (Free) | Max Weight (Checked) |
| Economy (Light) | 1 | 1 | 12 kg (26 lbs) | 0 | N/A |
| Economy (Standard/Flex) | 1 | 1 | 12 kg (26 lbs) | 1 | 23 kg (50 lbs) |
| Premium Comfort | 2 | 1 | 12 kg (26 lbs) | 2 | 23 kg (50 lbs) each |
| Business Class | 2 | 1 | 18 kg (40 lbs) | 2 | 32 kg (70 lbs) each |
Note: Checked bags must not exceed 158 cm (length + width + height). Allowances may vary for Flying Blue members.
KLM Carry-On Baggage Rules
KLM allows every passenger, regardless of ticket type, to bring at least one main bag and one accessory into the cabin. However, the weight limit is where most travelers get caught out.
1. The “Combined Weight” Trap
Unlike some airlines that only weigh your suitcase, KLM counts the weight of your main carry-on PLUS your personal item together.
- Economy & Premium Comfort: Your suitcase + handbag/laptop bag must not exceed 12 kg (26 lbs) combined.
- Business Class: Your suitcases + accessory must not exceed 18 kg (40 lbs) combined.
2. Size Restrictions
- Main Carry-On: Max dimensions are 55 x 35 x 25 cm (21.5 x 13.5 x 10 in). This includes wheels and handles.
- Personal Item (Accessory): Max dimensions are 40 x 30 x 15 cm (16 x 12 x 6 in). This must fit under the seat in front of you. Examples include a handbag, briefcase, or laptop pack.
Traveler Tip: On fully booked flights, cabin space is limited. Even if your bag fits the dimensions, you might be asked to check it at the gate free of charge.
Ensure you remove lithium batteries and essential medication before handing it over.
KLM Checked Baggage Allowance
Your checked baggage allowance depends entirely on your fare type and route.
Economy Light Fares
If you booked the cheapest ticket option (Light), you do not get a free checked bag.
You will need to pay to add one. It is almost always cheaper to add this online in advance (via the “My Trip” portal) rather than paying at the airport check-in desk.
Standard and Flex Fares
- Allowance: 1 checked bag.
- Weight: Up to 23 kg (50 lbs).
- Dimensions: Max 158 cm (L + W + H).
Business Class
- Allowance: 2 checked bags.
- Weight: Up to 32 kg (70 lbs) each.
- Dimensions: Max 158 cm (L + W + H).
Traveling with Children
- Children with a seat: Standard adult baggage allowance applies.
- Infants on lap: You are allowed 1 piece of checked baggage (up to 10 kg) and 1 carry-on item (up to 12 kg) containing baby care items. You may also bring a collapsible buggy/stroller for free.
Baggage Fees and Excess Luggage
If you exceed your allowance, KLM’s fees can be steep. Prices vary based on your route (e.g., within Europe vs. Intercontinental).
Purchasing Extra Bags
If you know you need more luggage, buy it online at least 24 hours before departure.
- Online Fee: Typically ranges from €20 to €70 per bag within Europe, and €30 to €100+ for intercontinental flights.
- Airport Fee: Paying at the airport usually costs double the online rate.
Overweight and Oversized Fees
If your bag is heavier than 23 kg (Economy) or larger than 158 cm, you will face a surcharge at the airport.
- Overweight (23kg – 32kg): Fees generally range from €75 to €150.
- Oversized (>158 cm): Fees range from €75 to €300 depending on the route.
- Hard Limit: KLM will not transport any single bag weighing more than 32 kg (70.5 lbs) or larger than 300 cm (L + W + H). These must be shipped as cargo.
Special Baggage Rules
Musical Instruments
You can bring a musical instrument (like a violin) as your carry-on if it fits the 55 x 35 x 25 cm requirement. If it is larger, you must book an extra seat or check it in.
Instruments checked in fall under normal baggage rules if it puts you over your allowance, you pay the excess fee.
Sports Equipment
Golf Gear
A set of golf clubs can usually count as one piece of checked baggage. If you are a Flying Blue Golf Club member, you may be able to bring one bag of golf clubs for free on top of your allowance (voucher required).
Bicycles
You must reserve transportation for a bike at least 48 hours in advance. There is almost always a fee (approx. €55–€100 each way), and the bike must be packed in a specialized box.
Ski/Snowboard
Generally counts as one piece of checked luggage if it falls within weight limits, but verify your specific route in “My Trip.”
4 Tips to Avoid Fees on KLM
Join Flying Blue
Even the base level “Explorer” membership gets you a discount on purchasing extra baggage. Silver, Gold, and Platinum members often get one extra checked bag for free.
Use a Luggage Scale
Because KLM weighs your personal item with your carry-on, the limit hits faster than you think. Weigh them together at home.
Upgrade Your Bundle
If you know you are checking a bag, compare the price of the “Standard” fare against the “Light” fare plus a baggage add-on.
Sometimes the Standard fare is cheaper than buying the add-on separately.
Pack Heavy Items in Your Coat
Your jacket does not count toward the weight limit. If you are slightly over the 12kg limit, wear your heaviest coat and put heavy items (like a power bank) in your pockets during check-in.
Final thought
If you need extra space, always book it online at least 24 hours before you fly to secure the best rate. A few minutes of planning now can save you significantly at the airport.
Disclaimer: Baggage policies and fees are subject to change. Always check the “My Trip” section on the official KLM website for the specific details of your booking before packing.
