Passengers could end up throwing their beloved possessions in the bin if they fall foul of hand luggage rules.
Brits heading on holidays with the likes of TUI, Jet2, easyJet, Ryanair, British Airways, Virgin Atlantic and more this summer need to be aware of what they can and cannot bring into the cabin with them.
We're not just talking airlines' cabin bag allowances - we're talking about the items you won't be allowed to take onboard at all in hand luggage.
While some of the banned items are fairly obvious and include, generally speaking, things that explode or are sharp, there are some red-listed things that you would be forgiven for thinking twice about packing.
Non-foldable umbrellas, scissors, lighter fuel and toy guns are just some of the examples - we've put a full list together below.
The main items banned from hand luggage include:
The list above includes the main items which are banned on all UK airlines in the cabin, but it is important to note that different aviation firms have different rules, as do different countries.
Some countries ban certain food items from being placed in hand luggage, so check with your airline or tour operator directly if you're unsure and you have something a little unusual in your bag.
Below is a list where you can get information for specific airlines including:
Airports also offer dedicated guides for passengers including Gatwick, Manchester, London Heathrow and Birmingham.
One big change that is currently being brought in across the UK is the amount of liquid you can bring with you in your hand luggage.
It was announced late last year that the strict 100ml liquid limit will be relaxed from June 2024, thanks to new scanners which let airport security see detailed 3D images of what is inside travellers' bags.
At London City Airport and Teeside Airport, passengers can now bring full-sized liquids through the security checkpoint up to two litres-and they no longer need to separate liquids into clear bags.
All airports in the UK are required to deploy the high-tech CT scanners by June 2024, at which point the liquid 100ml limit is set to end nationwide.
There are also items that are banned from both hand luggage and hold luggage, so make sure you have rid your bags of any of the below.
If you're unsure about a specific item, get in touch with your airline or tour operator direct who can advise as to whether you'll be allowed to bring it with you in your luggage.
