Cases you can take on flights

Protective cases that guarantee the safe transportation of your equipment

Whether you’re travelling with demonstration kits, prototypes, product samples, test equipment, or valuable electronics, protecting your items during air travel is essential.

While airlines offer convenient access to customers, suppliers, and colleagues around the world, transporting equipment by air presents unique challenges. Baggage handling, security screening, changing environmental conditions, and strict airline regulations can all put valuable items at risk if they are not packed correctly.

As a result, many businesses rely on specialist protective cases designed specifically for air travel. Often referred to as airline-approved cases, these solutions are built to provide robust protection while meeting airline size, weight, and transportation requirements.

In this guide, we explore key considerations when selecting an airline-approved case, including the regulations to be aware of and the most suitable options for different applications.

The need for airline-approved cases

Why would business travellers require specialist carry-on cases?

Before looking at the regulations and options, it is sensible to first identify why business travellers might need specialist cases when flying.

Whilst many will not require anything out of the ordinary – such as those taking laptops, paperwork, clothing, and other typically language-related items – many businesses will send employees to meet international clients (or potential customers) with specialist equipment, parts, or products.

This is particularly common where engineering companies have developed prototypes or test models specifically tailored to their customers’ needs. These will then be taken by employees to ensure that the items are not damaged or mislaid during transit.

Besides this, technical sales teams are likely to require these types of products, prototypes, or tools to successfully win business from potential customers abroad.

Another scenario is where specialist engineers visit existing customers or international locations to troubleshoot and repair specialist equipment, which in turn requires specialised tools and equipment.

All of these situations would require specialist airline-approved cases.

What are airline-approved cases?

Hand luggage vs hold storage

Whilst most airlines have a different interpretation, hand luggage is defined as bags, containers, or carriers allowed in the cabin of commercial flights. “Hold luggage”, however, is, perhaps obviously, any carriers, suitcases, and containers that must be placed on the aircraft’s hold.

Whilst the UK government no longer sets a maximum size for hand luggage, as it did prior to April 2010, most operators allow hand luggage or airline-approved cases measuring 560mm long x 540mm deep.

Nevertheless, it is becoming increasingly common for many airlines, particularly budget airlines such as Ryanair and EasyJet, to have their own restrictions on hand luggage and airline-approved cases.

Whilst they do vary between airlines, the general rule is that if they fit in the overhead compartment (or indeed under the seat in front of yours) then they can be carried on.

Therefore, it is always wise to check with the specific airline you are travelling with before you depart to either ensure that you can take your cases onto the plane with you or ascertain if it will be placed in the hold. It may also be the case that the airline’s own rules have recently changed.

ATA cases

Air Transport Association of America (ATA) approved cases

Another term you may or may not have heard of is “ATA-approved cases.” The Air Transport Association of America (ATA), recently rebranded as Airlines for America (A4A), is a trade body whose members include Boeing, Airbus, FedEx, and many others. Its aim is to “foster a business and regulatory environment that ensures safe and secure air transportation and enables US airlines to flourish”. However, many of its practices and guidelines have been adopted by airlines worldwide.

But what does that have to do with cases?

Well, one of the policies it implemented was the creation of the ATA Specification 300: Specification for Packaging of Airline Supplies. This set of guidelines provides a standardised approach to the design and construction of transit containers used to ship or transport items by air.

The document sets out the following six points specifically regarding cases/packaging:

  • Provide sufficient protection with a minimum of tare weight and cube consistent with optimum packaging versatility.
  • Ensure proper identification of material and containers.
  • Eliminate shipping damage due to packaging.
  • Reduce packing and unpacking costs.
  • Promote environmentally conscious packaging.
  • Accommodate security features to expose unauthorised access during shipment.

Besides this, there are various categories and criteria for cases to adhere to. Category 1 cases must be able to withstand 100 round-trip flights; Category 2, 10 trips; and Category 3, just one return journey.

There are other guidelines regarding the specific manufacturer and features of the case, depending on its type and use. Besides this, it also makes provisions for hazardous goods (such as lithium-ion batteries), testing procedures, and relevant labelling and markings.

Selecting airline-approved cases

Choosing a suitable case for your business

With all of this to consider, selecting an appropriate case can be somewhat daunting.

As such, the rest of this guide focuses on the different case options that you can use for business applications when travelling internationally. This covers:

  • Original ATA-approved case options.
  • Most suitable for transit in the aircraft hold.
  • Best carry-on case option.
  • Best option for protection.

Best for small items and equipment.

Original ATA-approved cases

Custom-built flight cases

The original specification, as set out by the ATA, effectively details what is known as a traditional “flight case” – the clue is in the name.

This includes the use of aluminium extrusion fittings, steel knuckle ball corners, piano-type hinges, and even acceptable wall/panel materials. It also recommends that transit cases of this nature be white where possible, while noting that other colours may be used for branding purposes as required.

As such, there are several benefits to using these types of flight cases for your air transit.

As the name would suggest, flight cases are the original ATA approved case option

Because they can be custom-manufactured to specific sizes, there is no excess weight or space in the cases, both of which can lead to higher shipping costs.

They can also feature elements to improve usability, such as castors, wheels, handles, locks, and, of course, custom foam inserts.

This makes them an acceptable option for transporting items in an aircraft’s hold, but, as we will detail, there may be more suitable options.

Best for shipping in the hold

Aluminium flight cases and transit cases

Whilst the ATA sets criteria for flight cases when shipping items by air, there is actually another case – also ATA-approved – that can be considerably more suitable for this application: aluminium cases.

The range of K470 aluminium cases from German manufacturer Zarges provide a number of advantages over traditional flight cases, including weight.

Because they are considerably lighter than flight cases, these cases are typically cheaper to ship than custom-built options.

They also offer a number of additional benefits, including strength, ease of handling, and optional wheels, easy-to-use handles, locking, and easy cleaning. These cases are also recognised as ATA-approved.

Their only slight drawback is that, because you have to select from a range of predetermined sizes rather than specify custom dimensions, you can sometimes be paying to ship fresh air or excess foam. However, this is most often offset by the overall weight saving.

As such, if you are planning on sending items internationally via air freight, aluminium cases would be your best option.

Best carry-on cases

Shell case standard 500

What about if you want to take your items onto the aircraft with you? What if you only have small items? What if the items are so expensive, delicate, or important that they can’t be put into the hold?

In that case, using a carry-on approved case is your best option, with the Shell Case Standard 500 range being the best all-rounder.

Looking very much like a hard-shell suitcase that a holidaymaker would use, Shell cases actually boast a range of additional features that make them perfect for professional use.

This includes a very tough polycarbonate shell for protection, integrated TSA locks, various branding options, particularly useful if the case will later be used in a sales meeting, and, of course, can be enhanced with foam inserts.

The size of the cases also means they can be stowed in overhead compartments, allowing you to keep a close watch on your important kit, products, or samples.

Best for protection

Peli™ and Storm™ cases

If you need the highest levels of protection for your items during transit, then a waterproof case with custom foam inserts, such as Peli™ Protector, Storm Case™, Explorer, etc., is definitely your best option.

The Peli™ Storm Caserange, suitable for use when travelling abroad, also boasts a wealth of additional features that make it ideal for either taking on the plane or stowing in the hold. The size range also helps here, with options suitable for either scenario.

They are manufactured from an exceptionally tough HPXresin exterior shell, are extremely sturdy, have strong, hard-wearing hinges, and feature press-and-pull latches for ease of use, and are also completely moisture- and dust-proof. They also come with a manufacturer’s lifetime guarantee.

When coupled with Plastazote® foam inserts, they will offer the highest possible protection from a case, and it is possible to create inserts that provide a very specific, calculated level of protection.

As such, for any engineers or technical sales teams with very expensive, delicate, or highly calibrated products or equipment, moulded waterproof cases are the go-to choice.

Carry on cases
Peli and Storm cases offer a wide range of sizes and are suitable as both carry on luggage and for stowing in the hold

Best for small items

Peli™, Storm™, and Hofbauer cases

Moulded waterproof cases are also a great choice for transporting small items when on board an aircraft.

However, as they provide such high levels of protection, they can be a bit bulky and heavy for every application, though this may be necessary depending on the items you are transporting.

As such, another option is light- to medium-duty plastic carry cases.

This includes cases from the likes of Hofbauer, WAG, Rose Plastic, Maxado, and others.

Within this, there are varying options of weight, durability, sizes and features, allowing you to find a case that is a good match for your equipment and/or products and that is also cost-effective, e.g., not too large or heavy.

Summary

Selecting an airline-approved case

If you are heading abroad to visit clients or other sites within your company, attending an important business seminar, or even travelling to install or service equipment internationally, then make sure you have a suitable airline-approved case.
