Do you have to pay to pick a seat on KLM? On most tickets, no, as long as you’re happy to wait until check-in and take a standard seat. On the cheapest Light tickets the rules are stricter. Here’s how KLM seat selection works, when paying is worth it, and how families can sit together.
The quick answer
- Most Economy tickets: choose a standard seat for free at check-in.
- Light tickets: if you don’t buy a seat before check-in, KLM assigns one at check-in. Changing it costs a fee.
- Before check-in: you can buy a seat during booking or in My Trip on any ticket.
- Check-in opens 30 hours before departure, or 24 hours for flights to or from the United States.

Free seat selection at check-in
If your ticket isn’t a Light fare, set a reminder for the moment check-in opens. That’s when the free standard seats become available to you, and the earlier you check in, the more choice you’ll have. Window and aisle seats go first on busy routes.
Light tickets
Light is KLM’s cheapest fare. If you don’t pay for a seat in advance, KLM gives you one during check-in and says it does its best to seat travel companions together. Light also has stricter baggage rules, so compare the total cost with a Standard fare before you book. You can compare KLM’s cabin bag limits alongside 24 other airlines before you choose a fare.
KLM seat types in Economy
| Seat | What you get |
|---|---|
| Standard seat | Standard legroom and recline. Free at check-in on most tickets. |
| Front standard seat | Standard seat in the first rows behind Economy Comfort, so you get off earlier. |
| Economy Comfort | More legroom and recline, near the front of Economy, early boarding. |
| Extra legroom (exit row) | Much more legroom. You must be willing and able to help in an evacuation, and can’t sit there with children under 12 or pets. |
| Seat in a row of 2 | On many intercontinental flights, pairs of seats at the back of the aircraft. |
| Adjacent empty seat | Block the seat next to you, offered at online check-in when available. |
KLM doesn’t publish fixed seat prices. The price depends on your route, the time of the flight, your Flying Blue level and other factors, and you’ll see it during booking or in My Trip.
Flying Blue members
Flying Blue Silver and Gold members can choose a standard seat for free before check-in, between 24 and 72 hours before departure depending on level. Platinum members can choose a standard seat for free at any time. Explorer members may see personal discounts on paid seats.
Families and seating
This is the part parents worry about most, and KLM is clear: on board, children under 12 always sit next to an adult on the same booking (under 13 on flights to, from or via Canada). At check-in, KLM assigns family seats for free and tries to keep everyone together.
- Babies under 2 can travel on a parent’s lap with a baby ticket.
- Bassinets on intercontinental flights are for babies under 1 year, under 10 kg and under 65 cm. Contact KLM to request one as early as you can.
- Car seats are recommended for children with their own seat. My family travel safety checklist covers the documents and packing for a trip with kids.
When paying for a seat is worth it
- Long-haul flights where legroom or an aisle really matters to you.
- Tight connections in Amsterdam, where a front seat gets you off faster. If Amsterdam is your last flight and you’re carrying on by rail, here’s how safe train travel in Europe is.
- A group that must sit together and is booked on Light tickets.
If none of those apply, check in the moment it opens and pick a free standard seat.
Frequently asked questions
Can I pick a seat for free on a KLM Light ticket?
Not before check-in. KLM assigns your seat at check-in, and changing it costs a fee. If seat choice matters, compare the cost of a paid seat with a Standard fare.
Will my family be seated together for free?
At check-in, KLM assigns family seats for free and tries to keep you together. Children under 12 always sit next to an adult on the booking.
Are seat purchases refundable?
Generally not, unless KLM changes your flight or seat for operational reasons. Read the conditions shown when you pay.
Is Economy Comfort worth it?
On long flights, many travelers find the extra legroom and recline worth it. On a one-hour hop, it usually isn’t.
