Check the aircraft on Iberia
A350 Next (Recaro CL6720): 10/10 for the seat. Only a small part of the A350 fleet has the door. Standard A350s and the A330 use the older Stelia Solstys seat: still 1-2-1 and still lie-flat, but open to the aisle. Recorded August 30, 2026.
A330 / standard A350 (Stelia Solstys): 8/10 for the seat. Same 1-2-1 lie-flat layout, no closing door. Recorded August 30, 2026.
Check the aircraft on KLM
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.
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.
