Croatia Airlines (OU) is one of the more pet-friendly small European carriers, partly because their hub in Zagreb serves a lot of Mediterranean leisure traffic where pets are often part of the trip. Cabin pet acceptance is solid on shorter European routes, though their codeshare flights with bigger carriers can have different rules. Nala has not flown OU, but Croatian friends report the cabin booking process is straightforward and the ground staff at Zagreb know what they are doing.

OU's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Frequently asked

What if my flight is delayed past my health certificate validity?
If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
What happens if I forget a document?
At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
For OU: book the cabin pet slot through their special services line at the same time as your ticket, confirm the aircraft type (regional jets and turboprops handle pets differently), and bring health documentation in English plus Croatian if possible. If your itinerary includes a codeshare leg with Lufthansa or another partner, verify the pet rules separately for each operating carrier. Build your plan against your departure date in Pawgo before booking.
