Most other major European airlines also have flights into Croatia, including Lufthansa, Alitalia, Austrian Airlines, Air France, CSA and LOT.
Some charter airlines operate seasonal services from the UK to coastal airports.
There are also numerous internal flights within Croatia (operated by Croatia Airlines), so if you're having trouble finding direct flights to a particular city, you could always fly via Zagreb.
