Remember though that airliners don't pressurise the passenger cabins at sea level but typically around 10,000 feet. Because of this the cabin air is thinner and may give people with asthma (and other respiratory conditions) some breathing difficulties. Also, ever since it was no longer legal to smoke in airliners, the airlines don't filter the air in an aeroplane as much as they used to (the filters cost money, and the filtration equipment adds weight), which means (believe it or not) the air in the cabin is not as clean as before the smoking ban came into force.
There's a rational argument that can be made against flying at all right now, me and Mrs Stigbob discussed it and stayed away from a hospitalized relative who is abroad. Not based on asthma just the chances of us popping along and exposing half the family. If I/we had asthma that would be another compelling reason for making exactly the same choice we already made.
The only question I have is why was the guy flying at all, checking the article he was on holiday flying back from Jersey a destination with cheap and regular ferries.
I've no sympathy at all for the utter fool.
