KLM Hand Luggage Size 2026: Cabin Bag, Checked Luggage and Fees

Updated: 5 October 2026

I booked an Economy Basic fare once because it was £40 cheaper than the next fare up. What I hadn’t factored in was that my usual cabin bag — a perfectly normal 55 x 35 x 25 cm suitcase — wasn’t included. Basic only covers a small under-seat bag, and sorting the suitcase out cost me more than the £40 I’d saved. KLM’s fare structure looks simple until you start packing for it.

KLM now has four economy fare types, not three. Economy Basic — introduced on 1 July 2025 on selected European and medium-haul routes — is more restricted than Light and isn’t included in most guides yet. Here’s the complete picture, with the correct fees and what’s actually changed in 2026.

KLM hand luggage size

Economy Basic — the most restricted fare

Economy Basic is KLM’s newest and cheapest fare, launched on 1 July 2025 and sold only on selected European and medium-haul routes. It includes one under-seat small bag only:

• Small bag: 40 x 30 x 15 cm (under-seat only)
• No overhead cabin bag included
• No checked bag included — both must be purchased separately
• No Flying Blue XP earned on this fare
• A cabin bag can be added via My Trip up to four hours before departure

If you see a very low KLM fare and want to understand what’s included, check the fare name carefully — Basic and Light look similar in price but the Basic is more restricted.

Economy Light

• Cabin bag: 55 x 35 x 25 cm (overhead locker)
• Small bag: 40 x 30 x 15 cm (under-seat)
• Combined weight limit: 12 kg for both bags together
• No checked bag on any route, including intercontinental flights — purchasable (€30–240 online on intercontinental routes)

On a city break with hand luggage only, Light is fine. If you need a checked bag, Standard is usually better value.

Economy Standard and Flex

Both fares include:

• Cabin bag: 55 x 35 x 25 cm (overhead locker)
• Small bag: 40 x 30 x 15 cm (under-seat)
• Combined weight limit: 12 kg for both bags together
• Checked bag: 1 x 23 kg

The 12 kg combined limit is worth understanding. If your cabin bag is 10 kg, your small bag must be under 2 kg. Packing a laptop in the small bag while your cabin bag is full is fine. Packing two heavy bags is not.

Premium Comfort

Same cabin allowance as Standard/Flex — one cabin bag plus small bag, 12 kg combined — but checked baggage is two bags at 23 kg each on intercontinental routes. Premium Comfort is not available on short-haul European routes.

Business Class

• 2 cabin bags (each 55 x 35 x 25 cm)
• Small bag (40 x 30 x 15 cm)
• 18 kg combined cabin weight
• 2 x 32 kg checked bags

KLM hand luggage dimensions

All dimensions include handles and wheels, which is how KLM measures. A bag that is exactly 55 x 35 x 25 cm on the outside including its wheels should be fine.

The Cabin Max Metz 30L at 45 x 36 x 20 cm fits within KLM’s cabin bag allowance. At 0.5 kg, it leaves nearly the full 12 kg combined limit for your actual belongings.

KLM checked baggage allowance

European routes

International routes

Checked bag size limits

• Maximum total dimensions: 158 cm (length + width + height)
• Maximum weight per bag: 32 kg — bags heavier than this are not accepted and must be repacked
• Maximum bags per passenger: 10 pieces total

A standard large suitcase (75 x 50 x 30 cm = 155 cm) fits within the 158 cm limit.

KLM extra baggage cost

Adding a cabin bag to Basic

Add this through My Trip up to four hours before departure. Adding at the gate costs more.

Extra checked bag fees

Exact fees depend on route and how far in advance you book. Adding online is consistently cheaper — sometimes by €50 or more per bag.

Overweight baggage fee

This is frequently misreported. At a growing number of airports KLM charges overweight bags by how far over 23 kg they are, in three weight bands:

Since 8 July 2026, flights between Europe and the USA or Canada use the same €40/€80/€120 weight bands (until 7 July 2026 they charged a flat €240 per overweight bag). Mexico may still be charged the flat €240 — check KLM before you fly. The fee is paid at check-in only — it can’t be prepaid online.

Bags over 32 kg are not accepted at all — they must be repacked. Pack to 23 kg if you are on Economy; pack to 32 kg maximum if you have Business allowance.

Oversized bag fees

Bags exceeding 158 cm total dimensions are considered oversized.

Sports equipment

Skis and snowboard

Free, and replaces your checked bag rather than being an extra charge:

• Maximum 300 cm total (length + width + height)
• Maximum 23 kg (Economy) / 32 kg (Business)
• A ski set = skis + poles + boots. A snowboard set = board + boots.
• No advance reservation required — bring it to the check-in desk.

This is one of KLM’s better policies. Many airlines charge €40–100 for ski carriage regardless of checked allowance.

Bicycle

Paid service, advance booking required (at least 48 hours before departure via My Trip):

Maximum 23 kg. Must be packed appropriately (pedals removed, handlebars turned).

Golf clubs

Free within your checked allowance (max 23 kg, max 158 cm dimensions). No extra charge if it fits.

Musical instruments

Smaller instruments can travel as your cabin bag if they fit within 55 x 35 x 25 cm. Larger instruments need a separate seat booking — contact KLM directly.

Travelling with a baby or child

This section is missing from almost every guide on KLM’s baggage policy. Here is what is actually included.

Infant allowance (under 2, travelling on your lap)

In addition to your normal fare allowance:

• 1 x 10 kg checked bag
• 1 hand bag with baby items (55 x 35 x 25 cm, max 10 kg)

Both are free and in addition to whatever your own fare includes. Worth knowing before you assume you need to add bags at booking.

Pushchair and buggy

• Collapsible pram (max 15 x 30 x 100 cm): free, in addition to normal allowance
• Can come into the cabin if it fits; gate-checked if not
• KLM does not provide a car seat — bring your own if needed

Car seat

Free, per child, in addition to normal allowance. Booster seats are not permitted on KLM.

Flying Blue status and baggage

Flying Blue is the shared frequent flyer programme of KLM and Air France. Status earned on either airline counts on both.

Flying Blue status baggage benefits apply on every KLM fare, including Economy Light and Economy Basic. On Basic, Gold, Platinum and Ultimate members also get one free cabin bag. Silver members get their free checked bag on Basic but not a cabin bag — they’re limited to the small under-seat bag unless they pay.

Practical example: A Flying Blue Silver member who booked Economy Light on a European route gets one free 23 kg checked bag added by their status. That can flip the value calculation on whether Light or Standard was the right fare.

Benefits also extend to a travelling companion on the same booking at Gold and Platinum level.

SkyTeam Elite and Elite Plus status (earned on partner airlines like Delta, Korean Air, Air Europa) also provides baggage benefits on KLM flights — typically +1 checked bag for Elite, +2 for Elite Plus. Check your status carrier’s specific agreement.

KLM and Air France codeshares — which rules apply?

On codeshare flights, the operating airline’s baggage policy applies — not the marketing carrier. Your booking confirmation or itinerary receipt is the definitive reference.

In practice, on most KLM-ticketed itineraries with Air France-operated legs through Paris CDG, the entire ticket uses KLM allowances if all flights are on KL flight numbers. If you see AF (Air France) flight numbers in your itinerary, check which aircraft is actually flying — on those legs, Air France rules may apply.

KLM has recently signed codeshare agreements with SAS and ITA Airways. On SAS or ITA-operated legs, those carriers’ policies apply. When in doubt, call KLM before you pack.

KLM vs British Airways vs Lufthansa

British Airways has the most generous cabin bag allowance of the three — larger dimensions and no published weight limit (you just need to lift it into the locker) versus KLM’s 12 kg. Lufthansa’s cabin bag is wider but the weight limit is lower. KLM sits in the middle. For the UK airline baggage comparison across budget and full-service carriers, see the full guide.

Check-in tips

• Online check-in opens 30 hours before departure — via klm.com or the KLM app
• Add extra bags online via My Trip up to 24 hours before departure, not at the airport
• The 12 kg combined cabin weight limit is enforced — staff sometimes weigh bags at check-in or at the gate
• Minimum connection time at Amsterdam Schiphol is 50 minutes for KLM-to-KLM flights; allow more on non-Schengen connections requiring passport control

Frequently Asked Questions

What is the KLM baggage allowance?
It depends on your fare. Economy Light, Standard and Flex include a cabin bag (55 x 35 x 25 cm) plus small bag (40 x 30 x 15 cm), 12 kg combined. Standard and Flex add one 23 kg checked bag; Light includes no checked bag. Only Economy Basic is limited to the small under-seat bag. Basic is KLM’s most restricted fare, introduced on 1 July 2025 on selected European and medium-haul routes.

What is the KLM hand luggage size?
The overhead cabin bag is 55 x 35 x 25 cm. The under-seat small bag is 40 x 30 x 15 cm. Both bags together must weigh no more than 12 kg for Economy fares. Business passengers get 18 kg combined and two cabin bags.

What is the KLM Economy Basic fare?
Economy Basic is KLM’s cheapest fare, launched on 1 July 2025 on selected European and medium-haul routes. It includes only a small under-seat bag (40 x 30 x 15 cm). No overhead cabin bag, no checked bag, and no Flying Blue XP are included. Both can be added separately.

What is the KLM overweight baggage fee?
At a growing number of airports the fee depends on how heavy the bag is. Within Europe it is €20 (23–26.4 kg), €40 (26.5–29.4 kg) or €60 (29.5–32 kg); on intercontinental routes €40, €80 or €120. Since 8 July 2026, flights between Europe and the USA or Canada use those same €40/€80/€120 bands (they were a flat €240 until 7 July 2026); Mexico may still be charged the flat €240, so check KLM before you fly. It is paid at check-in only. Bags over 32 kg are not accepted and must be repacked.

Do infants get a free bag on KLM?
Yes. Infants under 2 travelling on a lap get one 10 kg checked bag plus one hand bag with baby items (55 x 35 x 25 cm, 10 kg), in addition to the adult’s fare allowance. A collapsible pushchair and car seat are also free.

Does Flying Blue Silver status help on Economy Light?
Yes. Silver status gives +1 free checked bag on every fare, including Economy Light and Economy Basic. On a Light route that normally includes no checked bag, Silver status adds one 23 kg bag at no extra charge. On Basic, Silver does not include a cabin bag — only Gold, Platinum and Ultimate get one free.

What is the KLM checked baggage fee?
Online: €25 for a European route bag (Economy Light), then €20–70 for extra bags within Europe and €30–240 on intercontinental routes. Airport prices are significantly higher — often double. Always add bags online before you arrive.

Can I take skis on KLM for free?
Yes. A ski or snowboard set (skis/board + boots + poles, max 300 cm, max 23 kg) travels free as part of your checked allowance on all KLM fares. No surcharge.

How much does KLM charge for a bicycle?
Bicycle carriage is paid and must be booked at least 48 hours in advance. Fees are approximately €55 for European routes, €100 for most long-haul destinations, and €125 for USA and Canada routes.

Which KLM baggage rules apply on codeshare flights?
The operating airline’s rules apply, not KLM’s. Check your booking confirmation to identify which airline is actually flying each leg. If the flight number is AF (Air France), Air France rules apply on that leg.

Can I pool baggage allowance with other passengers on KLM?
Yes, if you are on the same booking. The total checked allowance for the booking can be distributed across bags, as long as no single bag exceeds 32 kg.

Does KLM weigh cabin bags at the gate?
Sometimes. The 12 kg combined limit is enforced. Staff may weigh bags at check-in or at boarding gates if bags look heavy. Packing close to the limit is fine; significantly over it risks a fee or being asked to check the bag.
