Zagreb Airport was linked to a record seven cities in Spain last year with a combined total of 238.715 passengers travelling between the Croatian capital and the Mediterranean country. The growth in connectivity between the two was driven almost entirely by Ryanair, which operates five of the seven routes, with three of them added last year alone - Palma de Mallorca, Girona and Alicante. Malaga remains the most popular destination, followed by Madrid, which is maintained seasonally by Iberia. Croatia Airlines is the smallest of the three carriers operating between the two markets, maintaining seasonal operations to Barcelona, which have been challenged by Ryanair’s service to Girona.

Croatia Airlines is adding new seasonal three weekly flights to Madrid from July 1 and increasing frequencies to Barcelona from three to four weekly between July and October. Ryanair is doubling frequencies to Palma de Mallorca this summer from two to four weekly, while Malaga sees an additional weekly service for a total of five rotations. Frequencies between Zagreb and Spain will peak in August with thirty weekly operations. The number of flights will vary over the remaining summer months between 21 and 27 weekly rotations.
This summer season there are a total of 262.332 seats on the market between Zagreb and Spain, representing an increase of 26.5% compared to last year, or an additional 54.926 seats. Ryanair will hold 62% of capacity with 162.204 seats, followed by Iberia with a 20% share and 53.942 seats. Croatia Airlines will have the remaining 18% of capacity with 46.186 seats on the market.

And these are even EU members since many years..
By the way Split doesn't connect onto Zagreb-Barcelona.
You have no idea how FR functions. Proximity is not disadvantage but totally opposite. In all cases of Sevilla and Malaga, both are huge and rich markets, and more frequencies to city pairs combined gives more options and opportunities. In case of Canaries one weekly is definitely not enough. So those three are highly likely to happen, and soon. I agree Bilbao has less chances but wouldn't say impossible. And there is another one which might start as well, Ibiza.
