KLM’s cabin baggage allowance is generous on most fares, but the airline’s cheapest Basic ticket strips things back considerably. This guide covers exactly what you can bring into the cabin with KLM, across every fare and cabin class, so you can pack with confidence.
Quick Answer
- Cabin bag dimensions: 55 x 35 x 25 cm (including handles and wheels)
- Personal item dimensions: 40 x 30 x 15 cm
- Combined weight: 12 kg in Economy, 18 kg in Business and Premium Comfort
- Checked baggage: Included on Standard and Flex fares, not included on Basic or Light fares
- Fare dependency: KLM’s Basic ticket only includes the small personal item, the main cabin bag must be purchased separately if needed
The most important thing to check before flying KLM is your specific fare type, since the difference between Basic and Standard significantly changes your cabin baggage allowance.
Cabin Baggage Allowance Explained
KLM’s cabin baggage allowance depends on your travel class and, importantly, your ticket type.
Maximum dimensions: 55 x 35 x 25 cm, including handles and wheels
Weight limit: 12 kg combined across your cabin bag and personal item in Economy, 18 kg combined in Business Class and Premium Comfort
A key detail that catches many passengers out is the combined weight limit. Unlike airlines that weigh the cabin bag and personal item separately, KLM adds them together. If your cabin bag weighs 10 kg, your personal item needs to stay under 2 kg to remain within the 12 kg Economy limit.
The other significant detail is fare dependency. If you’ve booked a Basic ticket, you’re only entitled to the small personal item (40 x 30 x 15 cm) free of charge, the main cabin bag isn’t included and must be purchased separately via My Trip, up to a few hours before your flight departs.
Personal Item Allowance
Every KLM fare, including Basic, includes a free personal item.
What qualifies:
- A handbag
- A laptop bag
- A small backpack
Common examples: A laptop bag with a tablet and charger, or a small backpack with a book and documents, both fit comfortably within KLM’s personal item allowance.
Under-seat storage: The personal item must fit under the seat in front of you.
Size restrictions: 40 x 30 x 15 cm, counted within the combined weight limit alongside your cabin bag (where applicable).
Because the personal item is included on every fare, including Basic, it’s possible to travel on KLM’s cheapest ticket using just this single bag, provided you can pack efficiently enough.
Cabin Bag vs Personal Item
KLM’s cabin bag, at up to 55 x 35 x 25 cm, is the larger item and goes into the overhead locker. It’s intended for clothing, toiletries and the bulk of what you’re bringing. The personal item, at up to 40 x 30 x 15 cm, stays with you under the seat for things you want easily accessible.
For example, a Standard fare passenger might use the 55 x 35 x 25 cm cabin bag for clothes and toiletries, while carrying a 40 x 30 x 15 cm laptop bag as their personal item with a tablet and travel documents, keeping both under the combined 12 kg limit.
A Basic fare passenger travelling light for a short trip, on the other hand, might rely solely on the 40 x 30 x 15 cm personal item to avoid the extra cost of adding a cabin bag.
Can You Take a Cabin Suitcase?
Yes, a cabin suitcase is a standard choice for KLM’s main cabin bag allowance, provided it stays within 55 x 35 x 25 cm including wheels and handles, and fits within the combined weight limit alongside your personal item.
The 35 cm width is narrower than some competing airlines allow, so it’s worth double-checking this specific dimension rather than assuming a bag marketed as “cabin approved” elsewhere will automatically fit KLM’s allowance. If you’re on a Basic fare and want to avoid purchasing the cabin bag add-on, consider whether a compact bag within the 40 x 30 x 15 cm personal item limit could work for your trip instead.
Restricted Items
Standard EU restrictions on cabin baggage contents apply to all KLM flights.
- Liquids: Containers must be 100ml or less, packed within a single transparent, resealable bag
- Electronics: Laptops, tablets and cameras are permitted, though larger electronics may need to be removed at security
- Batteries: Spare lithium batteries and power banks must travel in cabin baggage rather than the hold
- Sharp items: Scissors, knives and similar sharp objects are not permitted in cabin baggage
- Food: Solid food is generally permitted, though liquid or gel-based foods fall under standard liquid restrictions
What Happens if Your Bag is Too Big?
Gate checks: Oversized or overweight bags are typically identified at check-in or the gate using a standard bag sizer.
Extra charges: If your combined cabin bag and personal item exceed 12 kg (Economy) or 18 kg (Business/Premium Comfort), or your bag exceeds the size limit, it may need to be checked into the hold, with a fee likely to apply.
Possible delays: Repacking or checking a bag at the gate takes time, so it’s worth confirming your bag and its weight before travelling.
Tips for Avoiding Extra Fees
- Weigh your cabin bag and personal item together at home, since KLM’s limit is combined rather than per-item
- Double-check your fare type before travelling, Basic tickets only include the small personal item by default
- If you’re on a Basic fare, purchase the cabin bag add-on via My Trip in advance if you know you’ll need it, rather than assuming it’s included
- Choose a lightweight cabin case to leave more of your combined weight allowance for a laptop or other items in your personal item
- If you know you’ll need checked baggage, confirm whether your fare includes it, Standard and Flex fares typically do, Basic and Light typically don’t
Frequently Asked Questions
Can I bring a backpack? Yes, a backpack can serve as either your cabin bag or your personal item, depending on its size.
Can I bring duty free? Yes, duty-free purchases are generally permitted in addition to your cabin baggage allowance.
Can I take a handbag as well? Your personal item allowance can be a handbag. KLM permits one cabin bag and one personal item, so a handbag typically serves as the personal item rather than an additional item.
Can I carry medication? Yes, medication is permitted in cabin baggage, though liquid medication over 100ml may require supporting documentation.
Can I take a laptop? Yes, laptops are permitted in either bag and are commonly carried in the personal item for convenience during security.
Does KLM weigh cabin bags? Yes, and because the limit is combined across your cabin bag and personal item, it’s worth weighing both together at home before you travel.
What size suitcase fits? A cabin case around 54 x 34 x 24 cm gives a small margin under KLM’s 55 x 35 x 25 cm maximum, particularly useful given the relatively narrow 35 cm width.
Can I take a coat? Yes, wearing a coat onto the flight doesn’t count toward your cabin baggage weight allowance.
What’s included on a Basic ticket? A Basic ticket only includes the small personal item (40 x 30 x 15 cm) free of charge. The main cabin bag isn’t included and must be purchased separately.
Is checked baggage included on every fare? No, Economy Light passengers don’t receive a checked baggage allowance as standard, though it can be purchased. Standard Economy fares on European and intercontinental flights typically include one checked bag.
Do Business Class passengers get two cabin bags? Yes, Business Class and Premium Comfort passengers can bring two pieces of hand baggage, each up to 55 x 35 x 25 cm, plus one personal item, with a based combined weight limit of 18 kg.
What’s the maximum checked bag size? Checked bags must have total dimensions no greater than 158 cm, with weight limits of 23 kg in Economy and Premium Comfort, and 32 kg in Business Class.
Conclusion
KLM’s cabin baggage allowance is generous on Standard and Flex fares, a 55 x 35 x 25 cm cabin bag plus a 40 x 30 x 15 cm personal item, combined under 12 kg in Economy. The detail most worth checking before you fly is your fare type, since Basic tickets only include the smaller personal item by default. Airline baggage policies are updated from time to time, so it’s worth confirming the latest rules directly with KLM before you travel.
