We rely on guidance from scientific experts based on the results of a number of independent studies and evidence reviews - including Government commissioned research. The overall conclusion of those studies is that there is no positive evidence of a link between exposure to contaminants in cabin air and possible acute and long-term health effects, although such a link cannot be excluded.
“Accordingly, we continue to support the steps being taken by the European Aviation Safety Agency (EASA), which maintains responsibility for approving the safety of aircraft and setting aviation standards for European airlines, and is carrying out further research into cabin air quality.”
