Air Travel Guidelines for Patients with Nearly Resolved Pneumonia

Pre-Flight Assessment and Risk Stratification

The British Thoracic Society recommends that patients within 6 weeks of hospital discharge for acute respiratory illness, including pneumonia, undergo formal pre-flight assessment before air travel, which should include resting oxygen saturation measurement, spirometric testing if clinically stable, and history and examination focusing on current dyspnoea, exercise tolerance, and cardiorespiratory status 1
Patients with a sea-level SpO2 >95% are considered safe to fly without supplemental oxygen or further testing if no additional risk factors are present, according to the British Thoracic Society 2
The British Thoracic Society also recommends that patients with a sea-level SpO2 92-95% require risk stratification with hypoxic challenge testing, especially if additional risk factors exist 1, 2
Patients with a sea-level SpO2 <92% require in-flight supplemental oxygen, as recommended by the British Thoracic Society 1, 2

The British Thoracic Society recommends a standard flow rate of 2-3 L/min via nasal cannula for patients requiring supplemental oxygen during flight 2
For home oxygen users, the British Thoracic Society recommends increasing the baseline flow by 2 L/min during flight 2
The British Thoracic Society also recommends considering venous thromboembolism risk in patients with recent acute illness, and taking measures such as remaining mobile during flight, avoiding excess alcohol, and considering compression stockings if additional risk factors are present 1, 3

The British Thoracic Society recommends that current pneumothorax, severe unstable cardiac disease, and recent thoracic surgery are absolute contraindications for air travel, regardless of pneumonia status 2
The British Thoracic Society also recommends that patients with nearly resolved pneumonia planning air travel should carry rescue inhalers in hand luggage if applicable, avoid alcohol before and during flight, remain mobile or exercise legs during flight, and plan for medical needs at destination 1
