As of early 2026, Ryanair has implemented a strict policy where hot drinks purchased at the airport cannot be brought on board. If you are seen at the gate with a "to-go" coffee cup from a terminal cafe, you will likely be asked to finish it or dispose of it before boarding the aircraft. This policy is primarily cited as a safety measure to prevent scalding injuries from spills during boarding and takeoff, though critics suggest it also encourages the purchase of hot beverages from the onboard trolley. However, you can bring a cold coffee (like an iced latte) or a sealed, bottled coffee drink as long as it was purchased after security. If you bring your own insulated travel mug, you can often get it filled at the airport and carry it on, provided it has a leak-proof, screw-on lid, but even then, some cabin crews may enforce the "no outside hot drinks" rule strictly. To be safe, it is best to finish your hot coffee in the departure lounge and rely on the onboard service if you need a caffeine fix during the flight.
