Cabin bags
| What | When bought | Price | Charged | Source |
|---|---|---|---|---|
| Cabin bag added to a Basic fare within Europe (only on the few Basic routes) KLM sells one cabin bag (55x35x25cm, 12kg with the small bag) as an add-on to Basic, when booking, in My Trip, at online check-in or by phone, up to 4 hours before departure. It is priced per one-way journey and depends on the destination, but KLM gives no figure on its information pages. Consumentenbond reported in July 2025 (via DutchNews.nl) that it averaged EUR 28 on a return trip; that is an average, not a per-flight price, so it is not used as an amount. Light, Standard and Flex already include a cabin bag. | online, when booking | not published Paid for this? Tell us → | per person, per flight | source, checked 2026-10-24 |
| Cabin bag that is too big or too heavy, checked in at the airport KLM says a cabin bag that is too large or too heavy must be checked in for a fee, but gives no amount. On full flights KLM may put a cabin bag that meets the rules in the hold for free. | at the airport | not published Paid for this? Tell us → | per item | source, checked 2026-10-24 |

Within 24 hours of departure it often costs more (see the next fee). | online, after booking | €20 to €70 / ≈£16.81 to £58.82 | per item | source, checked 2026-10-24 |
| First 23kg checked bag within Europe, added in My Trip less than 24 hours before departure KLM says the bag can still be added in My Trip within 24 hours of departure but often costs more, and gives no figure. | online, after booking | not published Paid for this?

| First 23kg checked bag on a long-haul Light fare, added online (24 hours or more before departure) Per bag, each way.

Seats
| What | When bought | Price | Charged | Source |
|---|---|---|---|---|
| Seat selection: what KLM itself says KLM publishes no seat prices. It says the price depends on the route, the time of the flight, Flying Blue level and other factors, and shows it only when booking or in My Trip. On most fares you can choose a standard seat free at check-in (which opens 30 hours before departure, 24 hours for the USA). On Light, if you do not buy a seat, KLM gives you one at check-in and changing it costs a fee. Flex includes a free standard seat before check-in. Flying Blue Silver, Gold and Platinum members get free standard seats earlier. | online, when booking | not published Paid for this? Tell us → | per person, per flight | source, checked 2026-10-24 |
| Standard seat chosen before check-in, economy within Europe Paid before check-in on Basic, Light and Standard; free on Flex, and free for everyone at check-in (on Light a seat is given rather than chosen).

| Economy Comfort or extra legroom (exit row) seat, economy within Europe Economy Comfort seats have 5cm more legroom, more recline and early boarding; exit-row seats have about 15cm more legroom.
