And after your flight, make sure to come back and comment on the new retro-styled uniforms of Adria FA's. Some of them look EXTREMELY fetching in them. You'll find no "Malev-style" FA's on Adria

.
As for the airline itself - it's a decent, albeit small, full-service airline, serving mostly the big hubs out of LJU (LJLJ).
The Canadairs, while a tiny plane, are all very new, and extremely well serviced (Adria is the regional service provider for Canadair), so no one should fear flying this "small Eastern European airline"...
"Jože Pučnik" Airport is very much on the small side, the Duty-free is passable, and the lounge, as previous posters have said, is on the small side (and is shared by every airline that services LJU), so don't expect a hot meal to be available. A note - Taxis can be expensive (for various understandings of "expensive" - about 40 EUR from/to Ljubljana). if traveling on a budget, check out this page for the best option to get into town:
