Tui, Easyjet, Ryanair, Jet2 and British Airways rules on taking food on board planes

Airline food is not always the best and can cost you a lot of money on board. One way to avoid forking out is to bring your own food, either from home or bought in the departure lounge.

With retailers like Boots, Pret and M&S Food all present in UK airports, passengers can grab a cheaper sandwich or meal deal and save it for their journey.

Those who fancy being even thriftier can bring their own food through security and onto the flight, as long as it is not a liquid, like soup. Sandwiches and salads are usually fine - but make sure you eat it or dispose of it before landing as there are rules on the types of food you can take into other countries. The EU, for example, does not allow passengers to take fresh meat or dairy from the UK into its countries.

Some airlines' rules are clearer than others. However, easyJet, Ryanair, TUI and British Airways all do allow passengers to bring their own food on board. Jet2's rules are a little less clear but suggest cold food is fine. There are different rules for baby food, up to a litre of which can be brought on flights.

Remember, it is ok to take solid food through airport security, but not liquids. Any liquids must be in individual, clear bottles with a capacity of no more than 100ml.

You can not consume your own alcohol on flights, even if bought from Duty Free. If you want to drink booze on board, order it from the in-flight trolley

You can bring food on board, as long as any liquids (brought from home) such as soup or custard are in clear containers of no more than 100ml. Non-alcoholic drinks, including hot drinks, can be brought on board if they were bought in the departure
