Cabin air quality - Boeing 737-800
Discussion
So, I recently flew with Ryan Air from Lanzarote and I encountered a new phenomenon which really surprised me.
The cabin crew told us that there were several passengers on-board with severe nut allergies and they wouldn't be serving and food with nuts as an ingredient. We were also told that if we had brought on board any nut based food, not to open or consume it.
This got me thinking that, whilst we are all in a pressurized metal tube (the fuselage) why should it make any difference?
The air in the cabin is changed during the flight via the air conditioning but IIRC the amount of air changes are regulated as there is a cost involved as the incoming air is heated with bleed air from the engines.
Therefore more air changes equals greater fuel burn.
Is it me just being cynical, thinking Mr O'Leary is trying to make bigger profits or is it really an issue when in a confined space?
Incidentally we never had nut allergies when I was at school......... nobody died!

Bloody Ryan Air and their anti nut agenda. Daily Wail link for extra points
ETA I could've put the rolleyes, but you've already done it.

I actually think with Ryan you certainly get what you pay for.
Totally agree, the same with Sleazy Jet too.From a technical point of view, I noticed the seats were pretty thin (weight saving hopefully) and there were no elastic map pockets.
I'm guessing there is a decent enough weight saving by doing away with them, when all they do is print the safety information on the seat back in front of you. Makes perfect sense really.
Then of course you get the hard sell, Lottery scratch cards, drinks, food (nut free obviously
) perfume, booze etc.....It really is a flying cattle truck, but often the cheapest and/or only option.
I'd say from my experience EasyJet have upped their game a fair bit in the last couple of years and there's now a big difference between them and Ryanair.
In fact, now BA have stopped with the free food on short flights, there's little difference between them and EasyJet aside from slightly more legroom on the BA flight.
Fewer oiks and riff raff too on the BA flight I suppose.

one scoot up the aisle asking passengers for rubbish is all they get, no-one needs to spend time digging out stuff from the pockets

They save cleaning too as people dont leave their mess in the seatback pockets.From a technical point of view, I noticed the seats were pretty thin (weight saving hopefully) and there were no elastic map pockets.

Michael O'Leary's missing a trick here I think. If he'd in fact encourage nut consumption the hosties could sell EpiPens at a very affordable Euro 99 each or three for Euro 250.The cabin crew told us that there were several passengers on-board with severe nut allergies and they wouldn't be serving and food with nuts as an ingredient.

Yep, that thought did cross my mind. Leather seats too, only a quick wipe required, not as "clingy" as material. All done to pare down costs no doubt.one scoot up the aisle asking passengers for rubbish is all they get, no-one needs to spend time digging out stuff from the pockets
While we're on the technical thread..... why do you have to put the arm rest down for take off/landing. I was thinking that if it all goes a bit Pete Tong, then flailing limbs would just sustain more injuries from the arms sticking out between the seats? Obviously no mention of seat back being in the upright position as the seats didn't recline anyway!

I've only been on one flight in the past where they made the announcement that they couldn't serve nuts because of a severe allergy. I was surprised how "angry" people got about it - I guess people just like to moan when they are told they can't have it, even if there was no need/intention for them to have it in the first place.
You're all assuming that the air on a plane is clean and pure and has only previously been used by Angels
Surely its recirculated and put through soda lime to remove the CO2 with a bit of oxygen added from a cylinder to top up
Or am I being too cynical?
If so whats the score on full first with Qantas?
Please tell me it involves Kylie
