Your selected fare or add-on may change what is included. Use the checker option that matches your booking.
Official website, airline identity and baggage source verified during the 31 July 2026 airline content audit. Master airline record is complete; baggage-rule rows remain separately governed.
Your KLM allowance varies by fare or purchased option. Match the checker selection to your booking.
Airline staff may require the bag to fit completely inside a rigid airport sizer.
The return flight may depart from a different airport with different security procedures, and your baggage may be fuller after the trip. Recheck the KLM allowance before travelling home.
Where permitted, carry fragile, valuable or irreplaceable items with you rather than placing them in checked luggage. Pack cabin items so they remain protected during screening.
Pack a lightweight laundry bag or spare pouch inside your KLM cabin bag. Separating worn items makes the return journey easier to organise without adding unnecessary bulk.
Use this quick guide to compare your bag against KLM's published cabin bag and personal item limits. The WillitFit checker is designed to help travellers spot oversize bags before they reach the gate.
Measure the packed bag, not the empty manufacturer size. Bulging pockets, handles and wheels can affect whether the bag fits the sizer.
Keep documents, liquids and electronics easy to reach so you do not need to open and repack your bag during security or boarding.
A close result means there may be little tolerance. Use the checker, reduce soft contents where possible, and confirm the latest rules with the airline.
Airport and security
The return flight may depart from a different airport with different security procedures, and your baggage may be fuller after the trip. Recheck the KLM allowance before travelling home.
Airport and security
Where permitted, carry fragile, valuable or irreplaceable items with you rather than placing them in checked luggage. Pack cabin items so they remain protected during screening.
Baggage and packing
Pack a lightweight laundry bag or spare pouch inside your KLM cabin bag. Separating worn items makes the return journey easier to organise without adding unnecessary bulk.
Baggage and packing
Store permitted liquids in a sealed pouch inside your KLM cabin bag and place electronics, travel documents and cables in a separate compartment.
In-flight travel
Carry power banks in cabin baggage and keep them with you rather than in the overhead bin. KLM permits up to two power banks, subject to capacity limits, and prohibits using or charging them onboard.
Airport and security
Use separate, clearly grouped pockets for documents, liquids and electronics. This makes it easier to collect every item from security trays without delaying other travellers.
These terms are included naturally to help travellers and search engines understand the page topic without keyword stuffing.
