Iberia allows flat-faced pets on board and then points at a list of cabin conditions rather than at the breed. That is the right way round. Mochi has flown carriers that do the opposite, where the breed is the whole answer and no amount of preparation changes it. Here the preparation is the answer, and most of it comes down to weight.

Iberia's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

The cabin limit is a maximum weight of 8 kg including the carrier, and that total is what decides most bookings. The carrier itself often accounts for 1 to 2 kg of it, so the animal's own weight is not the figure to measure against. Weigh the pet inside the closed carrier on one scale and compare that total against 8 kg.
Snub-nosed pets can travel on board provided they meet the conditions for carriage in the cabin. That makes the published cabin conditions the gate rather than a brachycephalic ban. Read those conditions and check each one against the animal before booking, because failing a single one closes the only route this carrier offers a flat-faced pet.
Iberia is a reasonable choice for a flat-faced dog because it sets conditions instead of a ban. The work is weighing honestly against the 8 kg limit and reading the cabin conditions line by line. Build your plan around that weight first, and confirm the conditions on the day you book rather than the day you fly, because the carrier is what gets measured.
