How can flying on a plane affect a person with asthma?

Not usually: Since planes today are pressurized, changes in cabin pressure are not likely. Some people are very nervous when flying which in turn can be a trigger for an asthma attack. A confined area and a sensitivity to someone's perfume or other things can also be a problem. Good Luck

Take your inhaler: Taking your medications on board along with a peak flow meter are suggested. Avoid any known triggers when flying.

Mainly: rom triggers of asthma on the plane. The cabins are pressurized so this is not a problem.
