Companies have experienced disruption due to travel bans, slowing demand, and staff shortages. Less maintenance has been required since planes have been flying less frequently, resulting in decreased demand for spare parts. Cash flow shortages are a real problem and will continue until a full recovery has been made. Aerospace companies within both defense and commercial sectors will have an advantage as they do not rely solely on commercial aviation. However, defense spending is likely to decrease as governments battle to control expenses and reduce deficits. Boeing, in particular, slashed its 10-year forecast for new aircraft demand by 11% in 2020.
