There are already plenty of hand luggage rules to navigate when you're packing for holidays, but now one baggage handler has revealed there are some unwritten rules around your checked bags too.
In fact, there are some common items they have recommended people avoid packing altogether - or potentially risk causing some chaos behind-the-scenes.
In one of Reddit's popular 'ask me anything' forums, one user asked,"What do people commonly pack into bags that they should not?".
The anonymous handler shared their advice, going under the username RoyalBlueEyes, reports the Express.

Their top tip? Avoid packing food products - especially those that could leak.
They warned: "Food! Omg food... Please don't pack food or drinks in your bag. They rot, break, leak, open. It smells. Especially alcohol. Then I smell all day after picking up a bag that leaked on me.
"Same goes for cologne and perfume. Please wrap it well so it doesn't break." [SIC]
It's not the first time that holidaymakers have been urged not to pack food in their bags.
Most people know that you cannot bring liquids through security if they’re over 100ml.
You can take liquids under 100ml but these must be in a re-sealable plastic bag that can be no larger than 20cm x 20cm and cannot exceed one litre. Often, airports will provide these bags before security.
This also includes being banned from having more than one litre's worth of smaller bottles in your bag. However, these rules also extend to food.
Gov.uk states: "Liquids in containers larger than 100ml generally cannot go through security even if the container is only part full. There are some exemptions."
It may seem obvious, but what is classed as a liquid isn’t always as you expect - sauces, jams and preserves can also count.
There are also plenty of items that are generally banned from hand luggage and flights such as non-foldable umbrellas, scissors, lighter fuel and toy guns.
Meanwhile, airlines such as easyJet, TUI, Ryanair and British Airways each have their own hand luggage rules around what bags you can bring for free, and what items are banned from flights. (To give you a helping hand, we've put together a guide to airlines' rules here ).
