You are permitted to take water onto a Wizz Air flight in 2026, provided you adhere to standard international airport security regulations. You cannot bring a pre-filled water bottle through the security checkpoint if it exceeds 100ml (3.4 oz). However, you can carry an empty reusable water bottle through security and fill it at a water fountain or refill station inside the terminal before boarding. Alternatively, you can purchase bottled water at airport shops after passing through security and bring it onto the aircraft. Wizz Air, as an ultra-low-cost carrier, does not provide complimentary water or snacks during the flight; everything on their "Wizz Café" menu is available only for purchase. If you choose to buy water on board, you can expect to pay approximately €3.00 to €4.00 for a standard bottle. It is highly recommended to hydrate before the flight or bring your own purchased bottle to avoid the higher in-flight prices and the potential for service delays during short-haul routes.
