Flying with a medical condition

Travelling can be stressful at the best of times, and if you have a medical condition, it can add a few extra things to think about. Some conditions might make flying trickier, but that doesn't mean you have to miss out on your trip.

We've put together a simple guide to help you understand which medical conditions could affect your travel plans. Whether it's preparing for changes in air pressure, checking airline requirements, or knowing what support is available, a little planning can make all the difference.

Flying with Medical Conditions

Infectious Diseases

Some infectious diseases can stop you from flying, with flu being one of the most common. It's not just about feeling unwell—flu can be contagious for up to five days after symptoms start.

If you still plan to fly with an infectious disease, you may need a 'Fit to Fly' certificate from your GP. Some airlines check for unwell passengers at boarding, so it's best to be prepared.

Respiratory Conditions

Short-term respiratory conditions like pneumonia could stop you from flying, as they can cause breathlessness or be contagious.

If you have a long-term condition, you can usually still fly, but keep your medication or inhaler with you. If your condition isn't stable, you may need oxygen during the flight, which can be arranged with a fit-to-fly certificate.

Stroke

If you've had a stroke, most airlines recommend waiting 10-21 days before flying.

Strokes can also affect mobility, increasing the risk of deep vein thrombosis (DVT) on long flights. Booking extra legroom and moving during the flight can help reduce this risk. Try some in-flight exercises to keep your circulation flowing.

Heart Conditions

Flying puts extra strain on your heart, so if you have a condition like angina or heart failure, check with your doctor before you go. After a mild heart attack, most airlines recommend waiting at least 7-10 days before flying—longer for more serious cases.

Always pack any medication in your hand luggage. If you need oxygen on the flight, arrange this with your airline in advance. Staying hydrated and moving around the cabin can also help reduce risks like DVT.

Ear and Sinus Infections

Flying with an ear or sinus infection can be painful. Air pressure changes during takeoff and landing can cause discomfort, dizziness, or even a ruptured eardrum.

Using decongestants or nasal sprays before your flight can help, but if your symptoms are severe, it might be best to wait until you're feeling better. Chewing gum or swallowing frequently can also help with pressure changes.

Recent Surgery

Had surgery recently? You might need to wait before flying. Changes in cabin pressure can cause swelling, discomfort, and complications.

General guidelines:

• Keyhole surgery: Usually safe after 48 hours, but check with your doctor.
• Major surgery (e.g. abdominal, chest, joint replacement): May require at least 10-14 days.
• Eye surgery (e.g. cataract removal): Often fine after 1-2 days, but laser eye surgery can make cabin air more uncomfortable.

Quick Tips for Flying with a Medical Condition

Check with your doctor – Get medical clearance before you fly.

Bring documents – Carry prescriptions and medical records.

Tell your airline – Let them know about any special requirements.

Keep medication in your hand luggage – Don't risk losing it in checked baggage.

Stay hydrated and move – Drink plenty of water and stretch during the flight.

Travel Insurance for Medical Conditions

Do I Need to Declare My Medical Condition?

Yes. When booking your travel insurance, you need to declare any past or existing medical conditions. This makes sure you're properly covered if you need medical treatment abroad.
