Everything the airline won't tell you and your prosthetist forgot to mention.

The first time you fly with a prosthetic device, nobody prepares you for ‘that bit in the queue’....
The moment the scanner beeps, the officer looks at you and you have to explain yourself to a stranger while forty people behind you wait and try not to stare.
You know exactly what's happening but they don't and somehow it's your job to make it quick and comfortable for everyone else.
This guide is for that moment.
And for all the moments before and after it.
Pack your carry-on like you might never see your checked luggage again because occasionally, you won't. What can you NOT manage without? These go in your carry-on rather than in checked luggage. (Take it from someone who lost her prosthesis and entire hold luggage in Mexico city for 48 hours!).
Add the below to your carry-on;
the standard baggage cover on most policies is too low to replace a prosthesis. Most cap single items at £1,000 to £2,000. Your device almost certainly costs significantly more than that. Check your policy before you travel, not the night before your flight. Fish Insurance offers dedicated prosthetics cover that's worth looking at. And if you don't declare your amputation to your insurer and then need treatment abroad, your claim may be rejected entirely. Declare it. It costs nothing and protects everything.
It's important to understand your rights before you get to the queue. They are clearer than most people realise.

UK airport security will not ask you to remove your prosthetic limb as a routine part of security screening. This is confirmed by the UK Civil Aviation Authority, which sets the standards all UK airports operate under. You do not have to take it off. You do not have to show it. You do not have to justify wearing it.
In the US
The Transportation Security Administration states plainly that passengers are never required to remove prosthetic devices at security. You can be screened with imaging technology, a metal detector, or a thorough pat-down. Your prosthesis will need additional screening but removal is not part of that process under any circumstances.
In Europe
If you're travelling within the EU, rights vary slightly by country. The same principle applies - you should not be required to remove your device. However enforcement and staff training is less consistent than in the UK or US.
What will likely happen - in a majority of countries
Your device will most likely trigger the scanner. A security officer will carry out an additional hand search. This may be done in a private room by a security staff member of the same sex as you. You can request this private screening proactively, you don't need to wait to be offered it.
The officer will pat down the prosthetic area and run an explosive trace detection swab over the device and your hands. You might need to lift your trouser leg / sleeve for the swab. That's usually the extent of it. For US travellers, the TSA also runs a dedicated helpline called TSA Cares which you can call at least 72 hours before your flight to speak with someone about what to expect at your specific airport. It's worth using if it's your first time flying with a prosthetic device.
Even when you know your rights, being scanned, patted down, and explained to a stranger is wearing. It is completely reasonable to find it tiring. Knowing it's coming doesn't make it less annoying. It just means you're not surprised by it.

So you have made it past security, get on board the flight and then the flight itself becomes the next thing to navigate.
Aircraft cabins pressurise to the equivalent of 6,000 to 8,000 feet altitude. Combine that with hours of sitting still and your residual limb will likely swell and socket fit starts to slip. This ranges from mildly irritating to genuinely painful depending on the flight length and your device. There are a few things that help:
At the other end
If your device breaks abroad, the process is slower than it is at home but it can be manageable.
This is the most important financial risk of the trip and the most commonly overlooked one. Before you travel, confirm with your insurer in writing whether your policy covers prosthetic repair and replacement abroad and to what value (standard baggage cover almost never does).
If your device fails while you're away, call your prosthetist in the UK first. Many can advise remotely, identify whether the issue is socket-based or component-based, and point you toward appropriate local services. For upper-limb myoelectric devices, contact the manufacturer directly. Most have international support lines and can identify local service centres. The Limbless Association also maintains contacts across Europe and can help you find English-speaking prosthetists in major cities.
For shorter trips, a backup mechanical device or basic fitting is worth considering. It isn't elegant. But it means a component failure doesn't end the trip.
There's a version of this guide that ends with "with a bit of preparation, travel with a prosthesis is completely straightforward and you'll be absolutely fine."
This isn't that version.
Travel with a prosthesis is manageable and often its fine. Plenty of device users do it without incident. But it also involves explaining yourself to strangers more than you'd like, navigating systems that weren't designed with you in mind, and carrying a level of logistical awareness that other travellers simply don't have to think about.
That's not a reason not to go. It's a reason to go knowing what you're actually signing up for, so the reality doesn't feel harder than it has to.
The LimbMatch community includes device users who travel regularly and have routes, tips, and hard-won knowledge that don't exist in any official guide. If you're planning a trip and want to hear from people who've actually done it, come and ask. That's exactly what the community is there for.
