WizzAir is a Hungarian based airline, operating in the low-cost segment. Therefore, as a passenger, you are not granted and drinks or snacks during the flight. On the other hand, you have probably only paid 10€ for your flight anyway, so it should be obvious any service on board is for an extra fee. Below you can find an overview of what’s currently offered onboard WizzAir flights, but only for food and drinks, I have excluded the duty-free options. If you are interested in those, you should check out this pdf document provided online by WizzAir.
