Toxic airlines: Is your plane trip poisoning you?
thanks for all yr replies re olde jets getting fresher air
well that explains why we never got ill after long haul flights in the old days,
i worked as crew for a summer on BMA's 707-320C's fan jets (not the older turbojet 707-321's they had but i did fly as pax on them and dan airs too) and we never felt rough after those long flights...never dried out like a prune...and never went down with colds/sore throats.
on many a/c though you do smell on start up a whiff of fuel (more so in days past i recall...tristars were smelly
so it seems to me that when i fly now on a certain UK l/h airline i always get off feeling pretty terrible then usually get sick a day or 2 later,
so are they not giving us fresher air because of saving on fuel burn ?

The problem is with the "fresh" air. About half of the air that enters the cabin is comes unfiltered direct from the engines together with any contaminants that it contains, and the other half is recirculated air which does go through a filter of sorts.

Unfiltered, tottaly unfiltered??
Blimey....
There was a lot of fuss a few years ago about BAe 146's creating very bad symptons and the operator(s) denying everything...
One of the things that came out of this was reduced (inadequate) airflow due to fuel saving measures... it being suggested that this was becoming quite common, to reduce the total changes of cabin air.
..it being relatively easy to quote average air use per pax when resting, as opposed to what might be a decent factor over and above the minimum required. Remembering that we're cruising at what, a cabin altitude of 8,000 ft, then people will be breathing somewhat larger volumes of air than normal, and imagine this all taken into account - but nevertheless that is a lot of people in a small space...
Personally think a lot more care whould be taken over pax and cerw air quality... this IS supposed to be man's ultimate technolgical form of transport - let's get it right shall we

Even Dyson vacuum cleaners have pretty good exhaust air filtering...

Hey, there's even a marketing advantage here if an airline would specify an aircraft with a minimum air quality requirment sigificantly better than the norm.. presumably the norm being whatver the manufacturer's want to thro at them... after all, anything can go into the front of that engine, regardless of the oil... including enormous quantities of concentrated industrial pollution at certain altitudes... as for cruising over Chernobyl twenty or so years ago
Start with the long haul aircraft... ?

Like a fridge until the meal was served, then like a hot & stuffy oven until the "breakfast" was served
Pax full of food/drink + a nice warm cabin = lots of people off to sleep = no work for CC...

Dry air is normal on a plane, it's because air conditioning always dries out air because of how it works (though on a plane it's slightly worse as any additional air from outside is also very dry). For the same reason, unless somewhere *really* hot, the first thing I do when I get in a hotel room is to turn it off and open the window.
I find it similarly unpleasant on coaches, trains etc. However, unpleasant is all it is - the problem the BA crews are complaining about involves, AIUI, chemicals ending up in the air from the engines.
