Arriving in ZAG around 11:15 am, and the outbound flight on QR is not until 4:15 pm. I will have to check luggage in ZAG.

Presumably, the QR check-in will open exactly three hours prior to departure. So I'll check bags at 1:15 pm and head for the Zrinjevac Business Lounge.

But how to spend the two hours in between? I know, that's not a lot of time to kill but I'd still appreciate some quick replies.

I won't need more than a coffee or a water. Comfortable seating with my (large) bags would be the top priority..
