I curious what you ended up doing with this flight.

I'm in a similar situation for a flight I am looking to book at the end of April for BCN-JFK.

I'm interested in a PE seat and from some research have found a couple of things out:

1. LEVEL is finally in the process of getting its own air operation certificate so it can become a stand-alone airline instead of having to have Iberia officially operate all of its flights.
2. It appears as a part of this they have acquired at least one A330-200 from AirEuropa as some of the flights now are showing 6 rows of 2-2-2 - which maps to older AirEuropa equipment and how it was configured for business class previously.
3. It also now appears that some Iberia A330-300 may have been reassigned to Iberia as there are some flights now showing 1-2-1 seat configuration in the LEVEL premium class.

All of this makes some sense as it may just be LEVEL repurposing older equipment (instead of the brand new purpose-built A330-200s that they started with - the ones that have the 4 rows of 2-3-2 in Premium class) and keeping the cabin layout as it was. It certainly would save money until the cabins can be retrofitted with the appropriate premium configuration.

What I have not seen is ANY aircraft/seat layout with the 6 rows of 2-3-2 seating for Premium.

The closest I have seen - and what I am guessing is actually going on - is that these may be reassigned Iberia A330-200 planes that HAVE had the Iberia Business class cabin re-done to the LEVEL Premium configuration, but replaced the 5 rows of 1-2-1 with 6 rows of 2-3-2. If I compare the LEVEL seat map to the A330-200 seat map on SeatGuru they are the same with the above change.

From what I can tell right now, there are at least 4 configurations of LEVEL aircraft now flying (or being sold at least) for premium:

The original 3 rows of 2-3-2
The new 6 rows of 2-3-2
The configuration with 4 rows of 2-2-2 that appears to be the old AirEuropa aircraft.
The actual former Iberia cabin with 5 rows of 1-2-1.

My guess is that the last two options above will be converted to the 2-3-2 configuration (with however many rows are able to be fit into the old business class cabin) and we'll end up with the same two classes of service as LEVEL launched with, but differing amounts of seats in Premium.

Until then, it is very confusing. As I have been watching flights for the last couple of days I've seen the available seating configurations change for the same flight at least twice and one of the flights that was "sold out" for premium is now available again, but the cost for premium for that one flight is more than double the other flights... and that is on the aircraft with 1-2-1 so it would seem to be full lay-flat business class seating.

I think our schedule is going to end up with us on one of the 6 row 2-3-2 premium flights. Not my favorite as it indicates an older aircraft overall, but if my theory is correct, it probably means that the Premium cabin has been newly redone.
