Travel Safety for Older Adults With Respiratory Conditions: COPD, Asthma, and More

Respiratory Conditions and Travel: Finding the Balance

Respiratory conditions including chronic obstructive pulmonary disease (COPD), asthma, pulmonary fibrosis, bronchiectasis, and conditions resulting from previous respiratory infections are among the most common chronic health issues affecting older adults worldwide. They vary enormously in severity, from mild asthma well controlled by an occasional inhaler, to severe COPD requiring supplemental oxygen throughout the day.

The appropriate approach to travel varies accordingly. Many older adults with mild to moderate respiratory conditions travel internationally without significant modification to their plans. Others with more severe conditions require careful pre-trip medical assessment, specific preparations, and adjustments to their itinerary. A small number with very severe disease may be advised against certain types of travel, particularly long-haul flights. Understanding where your condition sits on this spectrum, through honest consultation with your respiratory specialist or GP, is the foundation of any travel planning.

What this guide provides is a framework for thinking about the specific considerations that respiratory conditions raise in the context of travel, so that you can have an informed conversation with your medical team and make well-prepared decisions about what is possible and how to do it safely.

The Effect of Flying on Respiratory Function

Commercial aircraft cabins are pressurised to an equivalent altitude of approximately 1,800 to 2,400 metres above sea level. At this pressure, the partial pressure of oxygen in the air is lower than at sea level, which means your blood oxygen saturation will be modestly reduced during the flight compared to your normal level at home.

For most healthy individuals and for many people with mild respiratory conditions, this reduction is not significant. For those with moderate to severe COPD or other conditions where baseline oxygen saturation is already reduced, this modest additional reduction can cause or worsen symptoms including breathlessness, fatigue, and in some cases, confusion.

A fitness-to-fly assessment, sometimes called a hypoxia altitude simulation test (HAST), can determine whether you are likely to need supplemental oxygen during flight. This test is carried out in a respiratory department and involves breathing a reduced-oxygen mixture that simulates cabin conditions. If your oxygen saturation falls below a certain threshold during the test, supplemental in-flight oxygen is recommended. Your respiratory specialist can refer you for this test if it is clinically appropriate.

If you require supplemental oxygen during a flight, contact the airline well in advance to arrange it. Most airlines do not allow passengers to bring their own oxygen cylinders on board, but most major carriers provide supplemental oxygen on prescription. You will need a letter from your doctor confirming the requirement and specifying the flow rate needed. Portable oxygen concentrators are permitted by many airlines with advance notification. Confirm the specific arrangements with your airline at least two weeks before departure.

Altitude and Destination Selection

High altitude destinations present a more sustained version of the reduced-oxygen challenge of flying. At altitude, less oxygen is available in every breath, and the body must work harder to maintain sufficient oxygen delivery. For people with normal lung function, this is managed by breathing slightly faster and deeper. For those with respiratory conditions, where this compensatory response may already be strained, high altitude can cause significant worsening of symptoms.

The degree of risk depends on the altitude and the severity of your condition. Popular destinations involving significant altitude include parts of the Andes (Cusco in Peru sits at 3,400 metres), the Himalayan foothills, parts of East Africa including approaches to Kilimanjaro, and many ski resorts in the Alps, Rockies, and other mountain ranges.

Discuss any high altitude plans specifically with your respiratory specialist before booking. Some patients are advised to avoid altitudes above 2,000 metres. Others can travel to moderate altitude with appropriate medication adjustments and gradual acclimatisation. A small number of patients with severe disease should restrict travel to near sea-level destinations.

Air quality is a related consideration. Cities with high levels of air pollution, including particulate matter, ozone, and nitrogen dioxide, can trigger or worsen respiratory symptoms. Many major cities in parts of Asia, South America, and elsewhere have air quality that is significantly worse than typical European or North American standards. Check the Air Quality Index for your destination during the time of year you plan to travel. Pack a supply of the relevant rescue medications and discuss air quality risks with your respiratory team before visiting heavily polluted destinations.

Packing Your Respiratory Medications and Equipment

Comprehensive medication preparation before travel is essential for any older adult with a respiratory condition.

Carry all respiratory medications in your hand luggage, never in checked baggage. Pack at least double the quantity needed for the trip, plus rescue medications in easily accessible quantities. Inhalers should be in their original packaging with the pharmacy label. Carry both preventer and reliever inhalers even if you rarely need the reliever at home, as travel-related triggers including dry cabin air, exertion, infections, and environmental changes may increase your need for rescue medication.

Obtain a doctor's letter listing all your respiratory medications with their generic names, doses, and indications. This is essential at border controls, where inhalers and nebuliser equipment may raise questions, and invaluable if you need medical treatment abroad.

If you use a nebuliser regularly at home, consider whether it is necessary to travel with one. Portable battery-powered nebulisers are available and suitable for travel. Check the voltage compatibility with your destination and carry the relevant plug adapters. If you use a CPAP or BiPAP machine for overnight breathing support, these are similarly portable and most modern units are compatible with international voltage standards, but carry adapters and confirm compatibility before travel.

If you travel with supplemental oxygen, plan the logistics of oxygen supply carefully. Home oxygen arrangements typically do not extend to international travel. Your oxygen supply company or your respiratory specialist can advise on arranging cylinder supply at your destination or on the use of a portable oxygen concentrator. This requires advance planning of several weeks.

Managing Respiratory Health During Travel

Several travel-specific factors can affect respiratory health beyond the altitude and air quality considerations discussed above.

Dry cabin air during long-haul flights can irritate airways and trigger or worsen symptoms in people with asthma or COPD. Stay well hydrated during flights. Use a saline nasal spray to keep nasal passages moist if this is something you find helpful. Some passengers find a comfortable face mask or humidifying mask useful on very long flights, though evidence for these interventions is limited.

Respiratory infections are a common travel hazard. The combination of recirculated cabin air, close contact with other passengers, exposure to unfamiliar pathogens, and the physical stress of travel all increase the risk of picking up a respiratory infection. For people with COPD in particular, respiratory infections are a common trigger for acute exacerbations that can be serious and may require hospitalisation.

Ensure vaccinations are up to date before travel, particularly influenza and pneumococcal vaccinations, both of which are recommended for older adults with respiratory conditions. Discuss any destination-specific vaccination requirements with your travel health clinic. Practise good hand hygiene during travel, particularly on aircraft, in airports, and in other crowded environments.

Have a clear, written action plan agreed with your respiratory specialist for what to do if your symptoms worsen significantly during the trip. This plan should specify when to use rescue medications, when to seek emergency medical attention, and what to tell medical professionals abroad about your condition. Carry this plan with you at all times.

Travel Insurance for Respiratory Conditions

Travel insurance for older adults with respiratory conditions requires specific attention. Standard policies often exclude pre-existing respiratory conditions, and the premiums for specialist policies that include them can vary significantly.

Disclose your respiratory condition fully and accurately when purchasing insurance. Undisclosed conditions will invalidate the policy at the point of a claim, leaving you personally liable for potentially very significant medical costs. Medical treatment for a serious respiratory exacerbation abroad, including intensive care, hospital admission, and medical evacuation, can cost tens or hundreds of thousands of pounds without insurance.

Ensure your policy covers: emergency medical treatment for your respiratory condition; hospital admission; medical evacuation to your home country; and the cost of any supplemental oxygen required as a result of your condition during or after travel. Read the policy carefully and confirm these elements are included before purchasing.

Some insurers have a telephone medical screening process to assess your condition and determine the appropriate premium. This is normal practice for specialist medical travel insurance and ensures the cover is genuinely tailored to your circumstances.

Enjoying Travel With a Respiratory Condition

The majority of older adults with well-managed respiratory conditions travel safely and enjoyably every year. With appropriate preparation, honest assessment of your individual risk profile, the right medications and equipment, and comprehensive travel insurance, a respiratory condition is a consideration to manage rather than a reason to stop exploring.

The destinations that suit older travellers with respiratory conditions best are typically those at or near sea level with good air quality. Coastal destinations, island holidays, and sea-level city breaks all offer rich travel experiences without the additional respiratory challenge of altitude or poor urban air quality. Within those parameters, the world remains a very large and rewarding place to explore.
