Can you fly with COPD?

Most people with stable COPD can fly. However, because aeroplane cabins have lower oxygen levels and different air pressure than sea level, you must have a Fit to Fly (Hypoxic Challenge) test if your lung function is below a certain level. Preparation with your airline regarding oxygen use is the most critical step.

Understanding Air Pressure and Your Lungs

When you fly, the aircraft cabin is pressurised—but not to sea level. At cruising altitude (around 30,000 feet), the cabin pressure makes it feel like you are at about 8,000 feet.

This means there is less oxygen in the air.

For a healthy person, this usually isn’t an issue. But with COPD, your lungs already work harder to absorb oxygen. This can sometimes lead to hypoxemia (low oxygen levels in the blood).

What you might feel:

More breathless than usual
Tired or fatigued
Less relief from resting compared to being at home

Even though you’re sitting still, your body is working harder to get enough oxygen. This is why planning ahead is so important.

The Fit to Fly Test: What to Expect

Before travelling, your doctor may recommend a Hypoxic Challenge Test (HCT), often called a “fit to fly” test.

The Process

You’ll breathe air that simulates high-altitude conditions for around 20–30 minutes. During this time, your oxygen levels are carefully monitored.

The Outcome

If your levels stay stable → You’re fit to fly without extra oxygen
If they drop → You’ll be prescribed in-flight oxygen at a specific level

Important Tip

Arrange this test at least 6 weeks before travel to allow time for planning.

Portable Oxygen Concentrators (POCs) vs. Airline Oxygen

If your doctor has advised that you’ll need oxygen during your flight, there are two main ways to arrange this. Understanding the differences can help you choose the option that feels most comfortable and practical for your journey.

Option A: Portable Oxygen Concentrators (POCs)

A Portable Oxygen Concentrator, often called a POC, is a small, lightweight device that delivers oxygen as you breathe in. Many travellers prefer this option because it gives them more control and flexibility.

What makes POCs a popular choice:

Airline-approved devices
Most airlines accept specific POC models, but you’ll need to check in advance that yours is on their approved list.
Freedom to move
Because the device is portable, you can use it not only on the plane but also in the airport and at your destination.
Battery requirements
Airlines require enough battery power to last 150% of your total journey time.
This is a safety buffer in case of delays, stopovers, or time spent on the runway.
Consistency
You’re using your own familiar equipment, which many people find reassuring.

Things to consider:

You’ll need to carry spare batteries, which can add weight
Not all POCs provide continuous flow (some are pulse-dose only), so you must ensure it matches your prescription
You are responsible for managing the device throughout your journey

Tip: Speak to your oxygen provider before travelling to make sure your device is suitable for flying.

Option B: Airline-Provided Oxygen

Some airlines offer oxygen onboard as a service, although this is becoming less common.

How it works:

Arranged in advance
You’ll need to request this service well before your travel date - often at least 1–2 weeks ahead.
Medical clearance required
Your doctor will usually need to complete a medical form confirming your oxygen needs.
Set delivery
The airline provides oxygen at a fixed flow rate during the flight.

Things to consider:

There is usually a fee, which can vary significantly between airlines
Availability may be limited, especially on smaller aircraft
You won’t have oxygen support in the airport - only during the flight itself

The Important Rule (and Why It Matters)

It’s very important to know that:

You cannot bring your own pressurised oxygen cylinders onboard a plane.

This rule is in place for safety reasons, as pressurised tanks can pose a risk during flight.

5 Practical Tips for a Smooth Journey

1. Special Assistance

Book wheelchair-to-gate support, even if you can walk. Airports are large, and conserving energy is key.

2. Early Boarding

Request priority boarding to avoid rushing and unnecessary stress.

3. Hydration & Humidity

Cabin air is very dry. Drink plenty of water and avoid caffeine to prevent dehydration and thick mucus.

4. Keep Medications Close

Have your rescue inhaler (e.g., Salbutamol) and prescription easily accessible, preferably in the seat pocket.

5. Check Your Destination Altitude

High-altitude destinations (like Mexico City or mountainous areas) can affect your breathing just like flying.

Securing Travel Insurance for COPD

Travel insurance is commonly considered an important part of planning a trip for people living with COPD.

Why It Matters

Emergency care abroad, especially if it involves oxygen or a hospital stay, can be very expensive. The right cover protects you from these unexpected costs.

Be Honest When Declaring

Always disclose:

If you use oxygen at home
If you’ve been advised to use oxygen during your flight

Missing this information could invalidate your policy.

Choosing the Right Cover

Many standard insurers don’t fully cover COPD. It’s important to choose a provider that specialises in respiratory conditions.
