Yes, you are permitted to bring your own food on board Jet2 flights in 2026, but the policy has specific nuances you must follow. You can bring cold food such as sandwiches, salads, crisps, and fruit, provided they do not have a strong or "pungent" odor (items like egg sandwiches or seafood are discouraged for passenger comfort). However, Jet2 strictly prohibits hot food and hot drinks from being brought onto the aircraft from the terminal. If you purchase a hot meal or coffee airside, you will likely be asked to finish it before boarding. Additionally, if you are flying to an EU destination (like Spain or Italy), post-Brexit regulations prohibit taking meat or dairy products (e.g., ham and cheese sandwiches) into the EU from the UK, meaning you should eat them on the plane or stick to vegan/plant-based snacks to avoid issues at customs.
