The business seats being compared
These are each airline’s best-scoring documented business aircraft. The fare grid does not identify aircraft, so the seat below is not promised with any fare in the table. Service and food require a separate firsthand review.

777-200ER / 777-300ER (sliding-door World Business Class): 10/10 for the seat. The door is documented for the refitted 777 product. Do not apply it to every 787 or A330. Check the flight's seat map and ticket type; lounge access and baggage can differ by fare brand. Recorded August 30, 2026.
A330-200 / A330-300: 5/10 for the seat. 2-2-2 lie-flat: the window seat requires stepping over a neighbor. Recorded August 30, 2026.
Check the aircraft on SAS
A330-300 / A350-900: 8/10 for the seat. This record covers the two named widebodies. SAS also documents an A321LR business cabin; this row does not establish its layout or the seat on a European connection. Check both directions of your booking. Recorded August 30, 2026.
Compare the fares and the routing
Each row compares the same airports, cabin, travel dates and observation date. It can still compare a nonstop against a connection. Journey times, aircraft, baggage allowances and change rules were not recorded with these fares; check those before treating the price difference as a saving.

Before paying for the ticket
- Check the exact operating airline and seat map on every long flight, including the return. An airline name or business-class label alone does not guarantee a flat bed or aisle access.
- Compare total journey time and connection length. A lower fare may buy a much longer trip.
- Reprice with your bags, preferred seats and change rules included. These observations do not establish that the tickets have identical restrictions.
- Check other airlines on the route. Being cheaper than the other airline on this page does not establish the cheapest fare in the market.
Common questions
- Is KLM or SAS better in business class to Europe?
- On the best documented aircraft, KLM scores 10/10 for the business seat and SAS 8/10. The aircraft on your booking decides whether those seats apply. Of 62 shared business routes, KLM was cheaper on 2, SAS on 59, and 1 was the same price. Service and food are not scored in this comparison. These are observations for travel November 8–14, 2026, not current quotes.
- Which is cheaper, KLM or SAS?
- Of 62 shared business routes, KLM was cheaper on 2, SAS on 59, and 1 was the same price. Of 79 shared economy routes, KLM was cheaper on 5, SAS on 74, and 0 were the same price. Both counts refer to travel November 8–14, 2026. A cheaper fare may involve a connection; compare the itinerary as well as the price.
- Will I get the business seat shown here?
- These cards describe the named aircraft in our cabin records, not a seat guaranteed on every flight. At least one of these airlines has a recorded aircraft or cabin variation. Check the operating airline, seat map and aircraft for every segment before paying; equipment can change. The fare observations do not record the aircraft.
- Has Jon flown these business cabins?
- KLM business class is not on Jon’s confirmed flown roster. SAS business class is not on Jon’s confirmed flown roster. That records the airline and cabin, not every aircraft or itinerary. This page compares documented specifications and dated fares.
