Seating
2 different configurations exists.
J/46 Y/251: Features 2 J cabins. First 8 birds and 12th(LWA-LWH
J/32 Y/304: The minicabin is removed and replaced with Y seating. Babycots in 1L and 41L. Birds 9-11, 13, 15 (LWI-LWL, LWN, LWP) has this config, a.k.a. marsuh�kki config.

Complete seatmap and layout of config 1 can be found HERE and config 2 is here.

Business Class features Zodiac Cirrus III full-flat bed seats in a 1-2-1 abreast config, all seats with direct access to the aisle. Config1 has two business class cabins, row1-8 and 9-12, while config2 only has one (row 1-8). Early reviews has preferred front cabin over minicabin, and for best window seat, row 2 or 1 may be preferable, row 1 for aisle seats.

As operations of A350 has matured, it has become practice to set the snack-bar on top of the cupboard in front of row 1, making row 1 experience a lot of foot traffic and noise.
Config2 also suffers from low toilet/pax quota (2 toilets / 32 pax) as the aft toilets has been assigned to the high density Y cabin, further contributing to high foot traffic in the front of the cabin. For these reasons, a seat further to the back may be preferable. However, all service start in the front and it will usually take a long time to get your meal in row 8.

For couples travelling together there is no clear choice. DH-seats are tilted towards each-other, but you still will not see the other person without leaning forwards. Seat across aisles (AD and HL respectively) has no barriers between them, but are tilted the wrong way and rows are also slightly misaligned.


Economy Comfort on A350 has the exact same seats as in economy, but with ≈4" inches more legroom. They also come with noise cancelling headphones, 1h internet, priority boarding and a small amenity kit.
Finnair platinums and OWE members can select these seats for free. (OWE must call to do so). Other passengers can select comfort seats for a fee, and seats are also sold after boarding.
On config1 comfort is row 21-25, while on config 2 comfort is row 21-24 + 25ABC and 25JKL. Row 21 is bulkhead and has slightly more space, as no seat reclines into the space. None of the configs has that super-space found on some retrofitted A330 though.

On config1 21AC and 21JL are the only paired seats making them preferable, but if you want to have IFE screen in the seat in front of you, pick row 22. On config2 all seats are in groups of 3, and it is also recommended to stay away from row 21 entirely, as it is entangled with the toilets.

In terms of space there are no seats in comfort cabin on either config that beats exit row 41A/C/J/L or 42A/L.



Economy Class features 3-3-3 abreast slimline seating with 32" pitch. The best seats are row 41 with most legroom on A/C/J/L (but they lack window), and row 42 A/L.
These are either labled "extra legroom" or "exit row" and are selectable with status or for a fee.
Economy cabin offers USB for charge - no AC outlets.


In-Flight Entertainment

IFE system is upgraded. Bigger screens, wider selection of movies and music, route mapper and control options. You can watch a movie from start to landing. You will have Bose noise-cancelling earphones in business class and in Economy comfort, and earplugs in economy class.
Wifi: you will see a code (in business class) in the screen when you open the IFE and select language. In economy class, you need to ask cabin crew for a voucher code if you are OWS/OWE, otherwise it costs you 7,95� per hour, 11,95� per three hours or 19,95� for the whole flight. It may take some time until up in the air to get it started. Log in is required, once you have created an account and password, the system will recognize you next time.

Quality issues and early refurbishment
The seats in business class have had many quality issues from day one. Apart from some inherent problems with the seat design, there are also malfunctions and abnormal wear.
As every row has slightly different pitch, fittings and trimmings have had to de adopted manually. Apart from causing delays in delivery, this also has led to many things in the cabin tend to come loose, to squeak and to break.

In june 2017 it was announced that Airbus has accepted responsibility for the quality issues and will replace every seat on every plane delivered until that point in time (9 birds).
The refurbish will take place during the first round of major maintenance round, scheduled to start later this year.

There is no information if there will be any changes made at the same time (addressing complaints about cramped seats and missing stowage space for example), but most likely this is treated as a warranty action and so cabin will be equipped with the exact same seats and layout, albeit with a newer batch of seats.
