Air travel can be challenging for individuals with breathing issues, lung diseases, or respiratory conditions like asthma, COPD (chronic obstructive pulmonary disease), bronchitis, or pulmonary fibrosis. The low oxygen levels, dry cabin air, and high altitudes inside an airplane can make breathing more difficult and increase the risk of shortness of breath, fatigue, or even medical emergencies.

If you have a lung condition or experience breathing difficulties, proper planning can make air travel safer and more comfortable. In this blog, we will explore how flying affects lung health, common respiratory challenges during flights, and essential tips to ensure a smooth and stress-free journey.

How Does Air Travel Affect Lung Health?

1. Reduced Oxygen Levels at High Altitudes

  • Airplane cabins are pressurized to 6,000–8,000 feet above sea level, meaning oxygen levels are lower than at ground level.

  • For healthy individuals, this might not cause noticeable changes, but for people with lung diseases, it can lead to low oxygen saturation, breathlessness, and dizziness.

2. Dry Cabin Air Can Irritate Airways

  • The humidity inside an aircraft is usually below 20%, which can cause dryness in the throat, nasal passages, and lungs.

  • This can worsen asthma, trigger coughing, and increase mucus buildup, making breathing more difficult.

3. Air Pressure Changes Can Affect the Lungs

  • People with chronic lung conditions may experience increased shortness of breath due to changes in air pressure during takeoff and landing.

  • If you have trapped air in your lungs (from conditions like COPD or recent surgery), you may feel increased discomfort or pain.

4. Increased Risk of Blood Clots (DVT)

  • Sitting for long periods in cramped airplane seats can slow blood circulation and increase the risk of deep vein thrombosis (DVT).

  • People with lung diseases like pulmonary hypertension are more prone to clots forming in the legs and traveling to the lungs (pulmonary embolism).

Essential Air Travel Tips for People with Breathing Issues

1. Consult Your Doctor Before Traveling

  • Schedule a pre-flight checkup with your pulmonologist or doctor to assess your lung function.

  • Ask if you need oxygen therapy or a "fit-to-fly" medical certificate for your airline.

2. Arrange for Supplemental Oxygen If Needed

  • If you require oxygen therapy, notify your airline in advance, as many carriers have specific policies for in-flight oxygen.

  • Bring a portable oxygen concentrator (POC) approved by the FAA (Federal Aviation Administration), as airlines do not allow standard oxygen tanks.

3. Stay Hydrated to Prevent Airway Irritation

  • Drink plenty of water to keep your airways moist and reduce throat irritation.

  • Avoid alcohol and caffeine, as they can contribute to dehydration.

4. Use a Mask to Protect Against Infections

  • The recirculated air in airplanes can increase the risk of respiratory infections, especially for people with weak lungs or compromised immune systems.

  • Wear an N95 mask to protect yourself from airborne viruses and bacteria.

5. Carry All Essential Medications

  • Keep your inhalers, nebulizers, and prescribed medications in your carry-on bag, not checked luggage.

  • Carry extra medications in case of delays and ensure they are in their original packaging.

6. Move Around to Prevent Blood Clots

  • Stand up, stretch, and move your legs every 1-2 hours to improve circulation.

  • Consider wearing compression socks to prevent swelling and deep vein thrombosis (DVT).

7. Manage Anxiety and Stress

  • If you have flight anxiety, practice deep breathing exercises to keep your lungs relaxed.

  • Bring noise-canceling headphones or listen to calming music to stay stress-free.

Who Should Take Extra Precautions While Flying?

People with the following lung conditions should take extra care while traveling by air:

  • Asthma – Ensure you have your rescue inhaler handy and avoid potential triggers like strong perfumes or dry air.

  • COPD (Chronic Obstructive Pulmonary Disease) – You may need oxygen therapy, so consult your doctor before booking a flight.

  • Pulmonary Hypertension – Low oxygen levels can worsen symptoms, so request in-flight oxygen if necessary.

  • Cystic Fibrosis – Stay hydrated, wear a mask, and clear mucus from your lungs before the flight.

  • Recent Lung Surgery or Pneumothorax (Collapsed Lung) – Air pressure changes can worsen symptoms, so seek medical approval before flying.

Final Thoughts: Breathe Easy While Flying

Air travel can be safe and comfortable for people with lung diseases and breathing difficulties if they plan ahead and take the necessary precautions. By staying hydrated, carrying medications, arranging oxygen support, and choosing the right seat, you can reduce respiratory discomfort and enjoy a smooth journey.
