Travel with POTS is mostly a test of standing still in places with nowhere to sit. Security queues, departure gates, station platforms, and passport control all ask you to stay upright and motionless, which is the position POTS handles worst. The NHS lists standing or sitting upright for long periods, getting too hot, and not drinking enough fluids among the things that can make symptoms worse (PoTS is how the NHS and UK charities write POTS), and a single travel day can hit all of them.

Because those triggers are known in advance, you can plan for them before you leave home. That’s the shift we want you to make. Book help, pack for your symptoms, and time your compression around the parts of the day when blood is most likely to pool.

We’ll start with why flights, trains and long car journeys affect POTS so much. After that come eight practical tips, set out in the order you’ll need them, from booking assistance to recovering on arrival. By the end, you’ll know exactly what to sort out this week and when to put your compression socks on, on the day you travel.

Is it safe to travel with POTS?

Most people with POTS can travel safely, including on long-haul flights, as long as they plan around their symptoms. The things that make travel hard for POTS, such as standing still, heat and dehydration, are predictable, so you can prepare for nearly all of them before you leave home.

Speak to your GP before you book if you’ve fainted recently, your symptoms have changed, or you’re starting new medication. PoTS UK points out that some airlines ask for a fitness to fly letter or a form completed by a healthcare professional, and that this can take time to arrange. If your airline needs one, you may not be able to board without it.

This guide is written specifically for people with POTS. If you’re a healthy traveller wondering about swollen ankles on a long flight, our guide to whether flight socks are the same as compression socks covers general air travel instead.

Why does travel make POTS symptoms worse?

Travel makes POTS symptoms worse because it piles up several known triggers at once. The NHS lists getting too hot, standing or sitting upright for long periods, and not drinking enough fluids among the things that can worsen PoTS. A typical travel day involves all three, often for hours at a stretch.

Flying adds another layer. PoTS UK warns that flying causes dehydration and can worsen symptoms, which makes sense given how dry cabin air is and how hard it is to drink enough when you’re worried about toilet trips. Then there’s the stress of delays, crowds and tight connections, which plenty of people with POTS find pushes their heart rate up before they’ve even boarded.

The upshot is simple. A journey that leaves a healthy person a bit tired can leave someone with POTS wiped out for days. Planning for each trigger separately is how you stop them stacking up.

8 practical tips on how to travel with POTS

These eight tips follow the order of a real journey, from booking to recovery. You won’t need all of them for a two-hour train ride, but on a long-haul flight or a full day of travel, each one earns its place.

1. Book around your best hours of the day

Pick departure times that match the part of the day when your symptoms are mildest. The NHS notes that PoTS symptoms are often worse in the morning, so a 6am flight that means leaving home at 3am is about the hardest start you can give yourself.

If mornings are rough for you, look for late morning or early afternoon departures, even if they cost a little more. Choose an aisle seat on planes and trains so you can stand, stretch, and walk without climbing over anyone. On long train journeys, a seat near the toilets saves a long walk through rocking carriages when you’re lightheaded.

2. Book free assistance before you go

Book airport assistance at least 48 hours before your flight. The UK Civil Aviation Authority advises requesting help when you book, or at least 48 hours before departure, through your airline, travel agent or tour operator. Assistance is free, and it can include a wheelchair to the gate, help through security and priority boarding.

Lots of people with POTS hesitate to book assistance because they can walk, just not for long and not whilst standing still. That’s exactly what it’s for. A wheelchair through a long terminal can save the energy you’ll need for the rest of the day.

For trains, the national Passenger Assist scheme lets you book help from rail staff, and the railway recommends giving at least two hours’ notice. Staff can help you find your seat, carry bags and get on and off the train. PoTS UK also suggests a Sunflower lanyard, which helps airport staff recognise that you have a hidden disability. You can usually pick one up at the airport assistance desk.

3. Sort out letters and paperwork early

Ask your airline whether it needs medical information as soon as you’ve booked. PoTS UK notes that your healthcare professional may charge a fee for a fitness to fly letter, and that these letters can take a while to arrange.

Whilst you’re at it, keep a short note on your phone listing your diagnosis, your medication and an emergency contact. If you feel faint at a gate abroad, being able to hand someone a clear note saves you trying to explain POTS whilst your vision is closing in. If you take medication, pack it in your hand luggage with enough to cover delays.

4. Put your compression socks on before you stand up

Put your compression socks on whilst you’re still sitting on the bed on the morning of travel, before you stand and start pooling blood. PoTS UK recommends wearing compression stockings when flying, and the NHS includes support tights or stockings among the first lifestyle changes for PoTS.

Graduated compression works like a hand squeezing a tube of toothpaste from the bottom. Pressure is strongest at the ankle and eases towards the knee, which nudges blood back up instead of letting it settle in your lower legs during hours of sitting. Our knee-high compression socks give 15-20 mmHg of graduated compression and are MHRA-registered, so they count as medical grade.

Fit matters on a long trip. A sock that’s too tight will dig in by hour three, and one that’s too loose won’t do much at all. Take five minutes to measure for compression socks in the morning before you order. Knee-highs also aren’t the whole answer for everyone with POTS, as some people are advised to wear firmer or longer garments. Our guide to compression socks for PoTS syndrome explains compression levels and lengths in more depth.

5. Drink more than feels normal

Drink more fluid than usual both before and during your journey. PoTS UK suggests taking an empty drinks bottle through security, and says flight attendants will fill it if you explain that your condition needs a high fluid intake. Avoid alcohol on travel days, however tempting the pre-flight drink is.

Plenty of people with POTS cut back on drinking when they travel because they don’t want to keep getting up for the toilet. That’s backwards. Getting up to use the loo is good for you anyway, since it gets your legs moving. If your GP has advised you to increase your salt intake, pack salty snacks so you’re not relying on whatever the trolley has.

6. Keep your legs moving whilst you’re seated

Avoid staying still for long stretches, and move your feet and legs often when you can’t stand. PoTS UK’s travel advice includes getting up to walk around when possible, exercising your legs and feet whilst seated, and raising your feet where you can.

Pointing and flexing your ankles, pressing your toes into the floor and lifting your heels all squeeze the calf muscles, which help push blood back up your legs. If you start to feel faint in a queue, the NHS suggests crossing your legs whilst standing, rocking up and down on your toes, or clenching your buttocks, tummy muscles and fists. Practise these at home so they’re automatic when you need them.

7. Pack a PoTS travel kit

Keep the things that help your symptoms in one bag you can reach without standing up.

Here’s what we’d put in a basic PoTS travel kit, and why.

The stool is the item most people forget, and the one they’re most grateful for. PoTS UK suggests portable stools for travellers facing long border queues, and they’re just as useful at taxi ranks and station platforms.

8. Plan for queues and build in recovery time

Expect at least one long queue, and plan the day after travelling as a rest day. PoTS UK has flagged that the EU’s Entry/Exit System, which registers travellers at the border, including at Dover, the Eurotunnel and St Pancras, may mean much longer queues for people heading to Europe.

Keep your compression socks on after you land too. You’ll still be standing at passport control and baggage reclaim, which is exactly when blood pools. Our guide on when to take off compression socks after a flight covers how long to leave them on. Once you arrive, keep the first evening quiet. If you push straight into a full itinerary, your body tends to pick the timing of the crash for you.

What about long car journeys with POTS?

Long car journeys with POTS need the same basics as flights: fluids, compression, and regular breaks to move your legs. Stop every couple of hours, get out and walk for a few minutes, and keep water and snacks within reach of your seat.

If you’re the driver, there’s an extra legal step. PoTS UK explains that by law you must tell the DVLA about any health condition that may affect your ability to drive, and that symptoms such as tachycardia, fainting and dizziness may need reporting. Reporting doesn’t always mean you’ll be stopped from driving, and the GOV.UK health conditions and driving page explains the process. If you’re unsure whether your symptoms count, ask your GP.

Can compression socks make POTS worse when travelling?

Compression socks don’t make POTS worse for most people when they fit properly, but they aren’t safe for everyone. Speak to your GP before wearing them if you have peripheral arterial disease, numbness or reduced feeling in your feet and legs, broken skin or an infection on your lower legs, or a heart condition such as heart failure. Our guide on who should not wear compression socks explains each of these in detail.

Poor fit causes most problems on long journeys. If the top band rolls or digs in after hours of sitting, it can restrict blood flow at exactly the point you want it moving. Smooth out any wrinkles before you sit down, and never fold the top over to shorten the sock.

Take your socks off and get advice if you notice tingling, numbness, colour changes in your toes, or pain in your calf. A painful, swollen calf after a long journey needs checking urgently, as it can be a sign of a blood clot. Contact NHS 111 or your GP, or go to A&E if you also feel short of breath or have chest pain.

Frequently asked questions

Do I have to tell the airline I have POTS?

You don’t have to tell the airline about POTS unless you need help or the airline asks for medical information. The UK Civil Aviation Authority says airlines need to know if you have a medical condition requiring extra care. Telling them when you book assistance makes it far more likely the right help is waiting for you.

What is the best seat on a plane if you have POTS?

An aisle seat is usually best for POTS because you can stand, stretch, and walk without disturbing anyone. Some people also prefer a seat near the toilets so trips are short. If you need extra space to raise your feet, ask the airline whether a bulkhead seat is available when you book assistance.

Should I wear compression socks on a short flight if I have POTS?

Many people with POTS wear compression socks for any travel day, including short flights. The time in security queues, at the gate, and boarding is often longer than the flight itself, and that standing time is when blood pools most. Put them on before you leave home rather than waiting until you’re on the plane.

Can hot destinations make POTS worse?

Yes, heat can make POTS symptoms worse. The NHS lists getting too hot as a common trigger for PoTS symptoms. If you’re heading somewhere warm, plan outdoor activities for cooler parts of the day, drink plenty, and keep a cool, shaded place to rest within reach.

Do I need special travel insurance for POTS?

POTS is a pre-existing medical condition, so you should declare it when you buy travel insurance. If you don’t declare it, your insurer may refuse to pay for treatment related to POTS whilst you’re away. Read the policy carefully and check that medical repatriation is covered.

Plan your next trip around your PoTS

Travelling with PoTS comes down to planning for the triggers you already know about. Book assistance early, pick departure times that suit your body, drink more than feels normal, and keep your legs moving whenever you can. Compression helps you handle the queues and the hours of sitting, and a rest day at the other end helps your body recover.

If you’re travelling this winter, start with the step that takes longest to sort out:

Book your assistance and check whether you need a fitness to fly letter. Then measure your ankle and calf, choose your size in our MHRA-registered knee-high compression socks, and order a second pair so you’ve got a fresh one for the journey home. Two pairs ship free in the UK.
