Yes, you are permitted to bring your own food on a Ryanair flight. For many budget-conscious travelers in 2026, this is a preferred strategy to avoid the relatively high prices of the "Ryanair Bistro" menu. You can bring snacks, sandwiches, and other solid foods through airport security and onto the plane. However, you must adhere to the standard liquid restrictions (containers of 100ml or less) for items like yogurt, sauces, or soups. While you can bring your own food, you are strictly prohibited from consuming your own alcohol on board, and hot drinks purchased after security are usually allowed as long as they have a secure lid for safety during potential turbulence. It is always courteous to avoid bringing particularly pungent or messy foods that might disturb fellow passengers in the often-crowded cabin of a low-cost carrier.
