Is it safe to fly with chest congestion?

Patients with active or contagious chest infections should avoid traveling until they are no longer infectious, as they may infect those sitting next to them. Flying is usually possible 7 to 10 days after the infection, even though the cough and mucus can last up to 3 weeks.

Pleurisy is an inflammation of the thin layers of tissue that cover the lungs and ribcage. It causes severe chest pain and difficulty breathing. Flying commercially while suffering from pleurisy is strongly discouraged. Pulmonary embolism and respiratory distress are the two most feared complications.

Infectious Diseases
An airline can deny boarding of any passenger who looks unwell, especially if they suspect the passenger might be infectious (infect other passengers).

However, if the breathing rate is already accelerated due to pneumonia and the traveller is unable to take in enough oxygen, this situation, and thus the patient's condition, can deteriorate further.

Resting Pulse Oximetry
Values >95% on room air suggest that inflight hypoxemia is unlikely and that further evaluation is likely not necessary. Patients with saturations <92% on room air at rest should receive supplemental oxygen inflight, because they are at high risk of hypoxemia at altitude.

Choose a seat in the middle of the plane. As the air circulates across the rows and not up and down the plane, some experts believe the worst air is in the front or the back of the plane. Stay well hydrated by drinking lots of fluids (water or fruit juice) and avoiding caffeine and alcohol, which will dehydrate you.
