NEWS FLASH
Japan Airlines (JAL) will be adding its designator code and flight numbers onto British Airways' service between London Heathrow and Zagreb starting next week. Both airlines are members of the Oneworld alliance. Japan Airlines passengers can now book flights to Zagreb via the carrier's website. British Airways will maintain five to seven weekly services between London and the Croatian capital this winter season, depending on the month. Japan Airlines becomes the third codeshare partner on British Airways' Zagreb operation, joining American Airlines and Qantas. Earlier this year, the Croatian government authorised the Minister for Sea, Transport and Infrastructure, Oleg Butković, to commence talks with his Japanese counterpart over the establishment of scheduled flights between Zagreb and Tokyo. The two sides will first have to sign a Bilateral Air Service Agreement, which has already been drafted, with Mr Butković expressing hope for negotiations to be swift in order for flights between the two capitals to be launched in the near future.

In 2019, some 215 000 Canadians are expected to visit Croatia, on an average Canadians spend around 3.5 nights in Croatia, slightly more than USD visitors who spend around 3 nights in Croatia. 576 000 US Visitors expected this year, 700 000 US Visitors expected next year.
I just wonder how soon before Air Canada starts year round service. Could be 2020?
@Current rate, in 2020, 255 000 Canadians and 850 000 US Visitors are expected to visitors Croatia. I think American and Delta will start direct flights to Zagreb and Dubrovnik in 2020,
United might too but not before 2022 I think.
Croatia is among top 25 destinations for US visitors already. For Canadians, Croatia is about to be top 20 Destinations.
These are really poor numbers for overnight stays (from an aviation perspective), because they show that most visitors from these countries still visit Croatia as part of a larger tour, which also means they arrive and depart from an airport outside Croatia (most likely Venice).
Zagreb and Croatia are still relatively unknown for most Canadians and Americans. However, direct service to Zagreb should improve connectivity and number of stays in the country.
Next year, Air Canada if my calculations are right will have around 105 rotations, that's 50 000 passengers in both directions, or 25000 in one, against 215 000 Canadians that will visit Croatia that year, it is not even 12%. So potential is there for more growth and better connectivity.
