KLM upgrade with miles: all options explained
You have a KLM Economy ticket and a pile of Flying Blue miles, and the seat up front is calling. The question is whether spending those miles to move forward actually pays off, or whether you are about to overpay for a few hours of comfort. Upgrading sounds simple, but the rules around when you can do it, which cabins are open, and what it really costs decide everything. This guide walks through every way to upgrade with miles, and shows you when a fresh award ticket beats the upgrade outright.

What is a KLM upgrade?
An upgrade means moving to a higher travel class on a flight you already have a ticket for. On KLM, you can upgrade from Economy to Premium Comfort or World Business Class, and from Premium Comfort to Business. You can pay with Flying Blue miles, euros at check-in, or a combination. But upgrading is not always the smartest move - sometimes a new award ticket is cheaper.
Quick facts
All upgrade options at a glance
There are several ways to move to a higher cabin on KLM or Air France. Each method has its own timing, costs, and chances of success.
| Method | When | Payment | Guaranteed |
|---|---|---|---|
| miles upgrade | Before check-in online or by phone; also from OLCI (30h before departure, 24h US) | Flying Blue miles | Yes, once confirmed |
| Paid upgrade | At check-in (30 hours before departure) | EUR, miles, or Miles & Cash | Yes, once confirmed |
| Operational upgrade | Day of departure | Free | No, extremely rare |
KLM cabins: what can you upgrade to?
Economy Comfort vs. Premium Comfort
KLM has two products that are often confused:
- Economy Comfort - seats with extra legroom (86 cm / 34 inches) within the Economy cabin. Available on all KLM aircraft, both European and intercontinental. This is not a separate cabin, just more legroom.
- Premium Comfort - a separate premium economy cabin with wider seats, more recline, dedicated service, and 13.3-inch screens. Configuration varies by aircraft: 2-3-2 on the 787 Dreamliner, 2-4-2 on the 777. Only available on widebody aircraft for intercontinental flights.
Possible upgrades on KLM
| From | To | Flights |
|---|---|---|
| Economy | Premium Comfort | Intercontinental (787, 777) |
| Economy | World Business Class | Intercontinental (787, 777, A330) |
| Premium Comfort | World Business Class | Intercontinental |
| Economy | Europe Business | European (737, Embraer) |
Europe Business is not a true Business Class: it is Economy with a blocked middle seat for extra space.
Upgrading with miles
You can upgrade an existing paid ticket with Flying Blue miles. In practice it depends on upgrade availability on your flight (fare rules often call this O-class); Flying Blue publishes no fixed rule for it.
How to request a miles upgrade
You do not have to wait for check-in. Flying Blue's official upgrade conditions split the process in two:
- Before check-in opens: open your booking on klm.com or airfrance.com and book the Reward Upgrade with miles, or call Flying Blue customer service. Platinum members have a dedicated Platinum Service Line and Ultimate members a personal Assistant; Gold does not get one. KLM also publishes a fallback page for periods when the online miles upgrade is down, so keep the phone route in mind. One catch: on a booking upgraded with miles before check-in, the flight can only earn miles on Flying Blue, not on a partner programme.
- After check-in opens: online check-in opens 30 hours before departure (24 hours for US flights). From that moment the upgrade also appears at the airport and on board, and you can pay in miles, in cash, or a combination of the two.
How many miles does an upgrade cost?
Flying Blue uses dynamic pricing, so there is no fixed table. The cost depends on your original booking class - the more expensive your Economy ticket, the fewer miles you need for the upgrade.
| Route | High booking class (Y, B, M) | Low booking class (T, E, N) |
|---|---|---|
| Short-haul Europe | 10,000 - 15,000 miles | 20,000 - 30,000 miles |
| AMS - New York | 15,000 - 25,000 miles | 45,000 - 52,500 miles |
| AMS - Cape Town | 20,000 - 30,000 miles | 40,000 - 52,500 miles |
Indicative amounts based on multiple sources. Actual prices are dynamic and may vary. Upgrade from Economy to Business Class, per one-way trip.
Measured: what members paid in miles for upgrades
Members' own statements set real amounts against the table above. Over the last 24 months, upgrades booked in advance with miles cost a median of 35,000 miles across all cabins and distances. Last-minute upgrades from Economy to Business, bought after check-in opens, cost a median of 10,600 miles across all distances. On flights of 4,000 km or more the median was between 30,000 and 60,000 miles, an indication based on 16 members.
SkyStatus member data, October 2026, based on 44 advance upgrades by 33 members and 157 last-minute upgrades by 80 members, from their own Flying Blue statements. The statements do not show the booking class, so they cannot confirm the split by booking class in the table. Our members are self-selected optimizers, not a random sample of Flying Blue members.
Full report: Flying Blue by the Numbers · Methodology
Important: with a miles upgrade, you earn XP and miles based on your original booking class, not at Business Class level. You fly Business, but your ticket remains administratively an Economy ticket. This is a key difference from booking a full Business Class award ticket. The one route that does earn the higher cabin XP is a rebooking into a Business fare, cheap only on Flex tickets: see the Flex exception in our check-in guide.
Paid upgrade at check-in
The most common way to upgrade on KLM is the paid upgrade that appears when online check-in opens, 30 hours before departure (24 hours for US flights).
Where to find the offer
- Online check-in on klm.com or in the KLM app
- Self-service kiosks at the airport
- Check-in desk
- On board - sometimes the crew offers upgrades when premium seats are left over
What does it cost?
The price depends on route, availability, your original ticket, and season. You can pay with credit card, iDEAL, or Flying Blue miles (or a combination).
| Route | To Premium Comfort | To Business Class |
|---|---|---|
| Short-haul Europe | - | EUR 100 - 200 |
| Intercontinental (Asia, Africa) | EUR 200 - 400 | EUR 250 - 550 |
| Intercontinental (North America) | EUR 200 - 350 | EUR 270 - 700 |
Prices per person, per one-way trip. Highly dependent on availability and season. Source: KLM.com, travel forums, February 2026.
Example: last-minute Business Class for EUR 200
On travel forums, travelers regularly report upgrade offers of EUR 200 - 350 for intercontinental flights to Business Class. A cash Business Class ticket on the same route easily costs EUR 2,500+, so the savings can be enormous.
These kinds of deals appear mostly on flights with many empty Business Class seats during the low season.
Upgrading vs. new award ticket: which is smarter?
The most important question when upgrading is: is it cheaper to upgrade your Economy ticket with miles, or to cancel it and book a full Business Class award ticket?
Scenario: AMS - New York, Business Class
Option A: upgrade (high booking class)
Option B: full award ticket
Scenario: AMS - New York, cheap Economy ticket
Option A: upgrade (low booking class)
Option B: Promo Reward award ticket
Air France and La Premiere
Air France offers the same upgrade options as KLM, plus one exclusive extra: La Premiere, Air France's First Class cabin.
Upgrade options at Air France
Just like KLM, you can upgrade at Air France before check-in opens or from online check-in (OLCI). The miles upgrades and paid upgrades work the same as at KLM:
- Economy to Premium Economy - comparable to KLM Premium Comfort
- Economy to Business - comparable to KLM World Business Class
- Premium Economy to Business
La Premiere: the ultimate cabin
La Premiere is Air France's First Class product, available on just 4 seats per aircraft on selected long-haul routes from Paris CDG. There are three ways to fly La Premiere:
- Award ticket: a route-dependent amount, roughly 165,000 to 285,000 miles one-way, and only bookable by Platinum and Ultimate members. Price it live in your own account rather than budgeting off a fixed figure. Note: you can reserve a maximum of 1 La Premiere award ticket per booking. If you are traveling with a partner, you always need at least 1 paid ticket.
- Cash upgrade from Business: EUR 1,500 - 2,600, offered inside the check-in window on a commercial (paid) Business ticket. When the offer appears, any traveller can buy it, whatever their status. Online check-in opens 30 hours before departure, 24 hours for US routes
- Miles upgrade from Business (Platinum and Ultimate): the same check-in-window offer, payable in miles by Platinum and Ultimate members only. Flying Blue director Ben Lipsey set out this path on 5 August 2026: it is an offer rather than an entitlement, so there is nothing to reserve in advance, online or by phone
Status benefits for upgrades
No status level entitles you to automatic free upgrades. This is a common misconception. Here are the actual benefits per level:
| Status | Upgrade benefits |
|---|---|
| Explorer / Silver | No upgrade benefits |
| Gold | No explicit upgrade benefits. Possibly slight priority for operational upgrades (not confirmed by Flying Blue) |
| Platinum | La Premiere in miles: the award ticket and the miles upgrade from Business at check-in are open to Platinum and Ultimate only. Priority for operational upgrades. EUR 70 change fees waived. |
| Ultimate | All Platinum benefits plus 4 upgrade vouchers per year. Flying Blue calls them one-cabin vouchers, so each voucher moves you up one cabin and an intercontinental Economy to Business upgrade, with Premium Comfort in between, needs two. |

Tips for the best chance at an upgrade
1. Check your booking class
Look at your ticket to find your booking class (the letter after "Economy", e.g. Y, B, M, U, K, H, L, Q, T, E, N). The higher the class, the cheaper the upgrade in miles. With class Y, B, or M, upgrading is almost always a smart move.
2. Monitor O-class availability
Regularly check whether there is award availability in Business Class on your flight. Availability often appears at opening (10-11 months before departure) or close to departure (last 2 weeks).
3. Check at online check-in
The paid upgrade appears 30 hours before departure. This is often the cheapest option when there are many empty Business Class seats. Also check the self-service kiosks at the airport - sometimes different offers appear there.
4. Combine Miles & Cash
A last-minute upgrade takes miles, cash, or both together, so being short on miles does not have to kill it. The published 25% cap applies to tickets, not to upgrades.
5. Always compare with an award ticket
Before spending miles on an upgrade, check the award availability for a full Business Class ticket. With a cheap Economy ticket, a new award ticket is often better value.

How many miles does an Economy to Business upgrade cost?
Flying Blue uses dynamic pricing. As a rough guide, an intercontinental upgrade costs 25,000 to 52,500 miles, depending on your booking class. A more expensive Economy ticket (class Y, B, M) costs fewer miles than a cheap ticket (class T, E, N). A miles upgrade depends on upgrade availability on your flight (often called O-class). You can book it before check-in opens, online in your booking or through Flying Blue customer service, and from online check-in onwards (30 hours before departure, 24 hours for US flights).
Can I upgrade an award ticket?
Not in advance, but yes once check-in opens. Flying Blue's official upgrade conditions state that reward tickets are only eligible for upgrades after check-in opens, so the last-minute upgrade in miles or cash is open to you while the advance Reward Upgrade is not. An award ticket is never eligible for an upgrade to La Premiere, and Flying Blue does not document Ultimate upgrade vouchers as working on one.
When is upgrading smarter than booking a new ticket?
Upgrading makes sense with a high booking class (Y, B, M, U): the upgrade costs only 15,000-25,000 miles. With a low booking class (T, E, N), the upgrade can cost 45,000-52,500 miles - almost as much as a full Business Class award ticket (60,000 miles). In that case, a new award ticket is usually better, especially during Promo Rewards.
What is the difference between Premium Comfort and Economy Comfort?
Economy Comfort seats offer extra legroom (86 cm / 34 inches) within the Economy cabin, available on all KLM aircraft. Premium Comfort is a separate premium economy cabin with wider seats, more recline, dedicated service, and 13.3-inch screens. Configuration: 2-3-2 on the 787 Dreamliner, 2-4-2 on the 777. Only available on widebody aircraft for intercontinental flights.
Does status give me a better chance at an upgrade?
No status level gives automatic free upgrades, and none lowers the price in miles: KLM's list of status benefits names no discount on awards or upgrades. Ultimate members receive 4 upgrade vouchers per year. For operational upgrades (when the airline relocates passengers), higher-status members get priority, but this is rare. Members' statements point the same way. Status made no real difference to the price of a last-minute upgrade: Platinum and Ultimate members paid a median of 10,050 miles from Economy to Business, and other members 10,700 miles (October 2026). Read more about Platinum status.
Do I earn Business Class XP with an upgrade?
No. With a miles upgrade or paid upgrade, you earn XP and miles based on your original booking class (Economy), not at Business Class level. You fly Business, but your ticket remains administratively Economy. This is a key difference from booking a full Business Class ticket. The exception is not an upgrade but a rebooking: changing a Flex fare into a Business fare reissues the ticket into a real Business booking class and does earn full Business XP. See the Flex exception.
