Ljubljana Jože Pučnik Airport is actively seeking out airlines for flights from the Scandinavian market. Although former flag carrier Adria Airways, which declared bankruptcy last September, served Copenhagen, Ljubljana has had poor connectivity to Northern Europe in recent years. Airport operator Fraport Slovenija says Scandinavia is a priority market for them. "Flights to Helsinki with Finnair resume this summer season and will be strengthened with an additional two weekly rotations, resulting in daily services. We are looking to connect Slovenia to Scandinavia with another airline", Fraport told the “Siol” portal. Ljubljana has been seeking better connectivity with Scandinavian countries for several years, with low cost airlines considered as potential operators.
Norwegian Air Shuttle previously said it was planning services to Ljubljana. Several years ago it noted, “Slovenia is definitely of interest to us in the future. We always explore the possibility to add new destinations to our network. This is a very important market for Norwegian. We’ve had scheduled flights to the Balkans since 2004 and our presence and network has grown every year". The two sides are believed to have held talks over potential services in 2017, however, no flights have materialised since. The airport is also believed to have proposed for Ryanair to introduce operations from Oslo to Ljubljana over a decade ago but ultimately no deal was reached either.
For its part, Fraport Slovenija noted, “Attracting new carriers is a continuous and never-ending process for us. We are constantly in discussions with at least fifteen airlines. We stick to the principle that we hold discussions with carriers and possible new routes are not publicly disclosed until they are officially scheduled in the timetable". This summer, passengers will be able to travel from Ljubljana to 22 destinations in fifteen countries with more than 160 flights scheduled per week. New routes include Madrid operated by Iberia, Tel Aviv by Israir, Kiev run by Windrose Airlines and London Luton operated by easyJet.

I don't think they will be expanding anywhere in foreseeable future.
What I'm seeking is that LJU is doing a good job under all current circumstances. I believe they will recover in number of destinations and passengers. Taken in consideration the construction of the new terminal as well.
Please, be precise in your answer.
@Anon12:44 FF programs have become more of a large-spender than a frequent-flyer. That was easy to implement while much of the world's economies were growing in recent years, but the next downturn will be the real test of this approach. Due to the size of Star Alliance and the many disparate interests within it, the various FF programs differ massively, but also feature more exceptions. Oneworld is much smaller and better integrated, with fewer exceptions in the FF programs, but in most of their programs inflexible economy tickets are pretty much worthless as well.
Last year, almost all Swedish airports saw a decline in travel.

Perhaps Denmark can work out. CPH is a generally more visited city compared to OSL or HEL for example.
