Yes, you can eat and drink on Ryanair flights. Though there is no complimentary in-flight meal service, Ryanair does allow you to bring food and drinks on board. However, you may not bring any liquids that exceed 100ml. These restrictions are in line with regulations from the European Aviation Safety Agency (EASA).

Yes, you are absolutely allowed to bring your own food on a Ryanair flight, which is a common strategy for budget-conscious travelers to avoid the airline's "Getaway Café" prices. You can bring snacks, sandwiches, or cold meals from home or purchase them at the airport after passing through security. However, there are two important restrictions: first, you cannot bring hot drinks or your own alcohol on board for consumption (alcohol must be purchased from the inflight menu). Second, any liquids or semi-liquid foods like yogurt, hummus, or soups must still comply with the standard 100ml liquid rule at security. Most regular flyers recommend picking up a "meal deal" in the terminal for convenience. The cabin crew generally does not mind you eating your own food, though they may ask you to refrain from eating particularly "aromatic" items out of respect for other passengers in the cramped cabin environment.
