The government of the entity of Republika Srpska in Bosnia and Herzegovina is in the final stages of talks with a private Russian carrier over the introduction of three weekly flights between Moscow and Banja Luka. The entity's Minister for Transport and Communications, Nedjo Trninić, said, "These negotiations are in their advanced stages. We already have a draft agreement in place. If all goes to plan, as we expect, flights between Moscow and Banja Luka will commence in April. A total of three weekly services are planned and we are fully engaged on this matter". The Minister did not reveal the name of the Russian carrier in question.
On the other hand, Ryanair is set to launch flights between Berlin and Banja Luka on April 3, while Mr Trninić believes that additional new routes will be introduced by the budget carrier later this year. "We are preparing an autumn surprise, but I will keep that a secret for now", Mr Trninić said. Berlin will become Ryanair's fourth new destination from Bosnia and Herzegovina's second largest city. "We have given our proposals to Ryanair concerning new routes. Of course, it is up to them to make a final decision based on their research, however, I expect at least one more new and interesting destination to be announced", Mr Trninić noted.
In addition to Ryanair's expansion and the planned flights from Moscow, Banja Luka Airport will also see charter flights to Antalya and Athens this summer. "In 2019, we anticipate for Banja Luka Airport to handle over 130.000 passengers, which would make it a record year", General Manager, Duško Kovačević, said. Banja Luka Airport handled 36.180 travellers in 2018, representing an increase of 73.4% on the year before. The bulk of the growth came during the last two months of the year, when Ryanair launched operations to the city. "With four routes this year we will help deliver over 135.000 customers through Banja Luka Airport", the low cost carrier said.

I think we should be careful with our predictions for autumn not to be disappointed when the announcement is made. :)
I can also see them working on a year round basis if there is some type of codesharing with Agean for connections out of ATH.
The demand that those markets have and the number of routes launched prove how incompetent previous managers were.
Just my2cents
Is it just my observations or are Russian airlines "borrowing" from other brands:
>>> Pobeda and Jat's 3 dots
>>> Rossija and Roger Federer's R
>>> Utair and United Airlines' U
It is a small AND a poor city.
Worth noting also that Podgorica is the capital of an independent country with a major tourism industry.
Now, which of the other airports you've listed is served by Aegean?
In any case, I love the city of Banja Luka but a dose or reality needs to be injected from time to time.
By that logic BEG is way ahead of everyone else since it's the only airport to have year-round flights by Aegean.
As for BNX, say what you want but they are one of the few cities in ex-YU to have charter flights that are filled (to the gills) by outbound demand.
In 2019 I think the airport will handle around 120.000 passengers.
Hahahahahaha!
When was the route launched? I will check once the numbers become available for winter. I know AMS-LJU affected AMS-ZAG big time.
As for the catchment area, naturally BNX covers northern Srpska and Slavonija. Someone who lives in continental Croatia doesn't care if he flies from OSI, TZL, BNX or ZAG. For example, take someone who lives in Pozega (HR) and who needs to fly to Berlin. Why should he go to ZAG when Tuzla and Banja Luka are right there and are probably cheaper to fly out of. Same way people from OSI fly out on charters from BEG.
Same story was on this blog about INI, not long ago.
BNX
Population (2013 census)[1]
• Urban 199,191
• Metro 274,914
Population (2011)[3][4]
• Rank 3rd in Serbia
• Urban Increase 209,544a
• Metro Increase 240,279a
• Administrative Increase 282,245a
Basically they are extreme lookalikes.
In general, it seems that by 2019 we can see BiH handling possibly 2 million aiports which is what Macedonia has with its 2 airports:

This means that there is definitely room for much more flights from Bosnia.
I am shocked that most airports in BiH are doing well. 1,7 million is not a bad figure, tbh.
That said, there will be now a new Bosnian race between BNX and TZL.
W6 are currently expanding and have problems with Fiumicino Airport relocating to Ciampino.
Same old Italian drama and headache.
