If you are planning to travel by air any time soon it may be a good idea to brush up on the new hand luggage rules before booking your ticket.

Hand luggage only tickets are a great way to save money, but with size and weight restrictions, not to mention cost, constantly altering passengers could find themselves facing a hefty fine at the airport.

As well as issuing fines for suitcases that exceed the luggage allowance, some airlines have a restriction on the number of cabin bags allowed in the aircraft and will ask for luggage to be placed in the hold – free of charge.

Having to place hand luggage in the hold may not be an issue for most but those carrying valuables, including gadgets and laptops, may not be keen on the idea.

Personal possessions, usually electrical items, jewellery, watches and eyewear, that have been placed in the hold are classed as ‘unattended’ and will not be covered by most travel insurance policies.

It’s worth noting if you are carrying gadgets, they are often not covered as standard on many travel insurance policies, some providers will ask for an additional premium to be paid for a gadget extension. However, there are some companies that will offer cover for gadgets as standard, you can read more here.
