Personal Air Vents Vs Central Cooling Only

Fri Jul 06, 2007 10:31 am

I always enjoy having a personal air vent above my seat and I have noticed almost all American carriers have these personal air vents on all flights. However, why do many of the best airlines like Singapore, Cathay, Ethiad, British Airways, Air France, Air New Zealand and Continental not have these personal air vents installed? It just doesn't seem to make sense that the "Top" airlines do not have them. They are always updating their product offerings yet they don't offer simple air vents to keep their passengers cooler? Why?

Also, I have never traveled on an airline without the personal air vents. Is the central cooling system stronger to make up for the fact that passengers do not have their own air vents?

Good to see Air Canada, Delta, Emirates, and I think Jet Airways do have them!

DL has them on all birds except the ex-Gulf 767s and the ex-ATA 757s.
Some see lines, others see between the lines.

How airplanes in their fleet do not have them?

Personally I love the individual vents. Many years ago I flew SYD-LAX in cattle car and the guy next tome was the type that only took a bath on the first of month - and we were flying at the end of the month. I turned that vent on full and kept it aimed on my face the entire flight. At times they can be really important on a flight.

The central systems are generally OK, but fail to take into consideration the personal preferences of individual pax. Men tend to want more cooling than women and thin people get cold faster than the more insulated ones. My guess is that it is cheaper to install and uses less fuel on longer flights.

Boeing airplanes without the valves are already plumbed for them. All that is missing is a flexible hose (about 1-2') and the valves that you twist. Why DL has not added them to the planes without, I don't know.
This plane is built to withstand anything... except a bad pilot.

It's an option from the factory. American's 767s don't have them, for example.
It's more rare on widebodies than it is narrowbodies.
I don't remember them on the US A330s either, I don't think.

Are there plans to put them in those planes?

The 738's I was on in December 2006 had them. I needed the one on CLE-PHX too, they had really made the cabin warm and it was too hot for my comfort.
I love ASO!

There are 6 763-3P6s (the ex-GF machines). The lone 763-324 has the same door configuration as the -3P6s; I don't know about air vents on it.

There are 4 752-212s. There is also a lone 757-26D (N900PC) which may also lack them.

So it's somewhere between 10 and 12 birds, assuming the info on which birds don't have them is correct.
I can't decide whether I miss the tulip or the bowling shoe more

I like the air vents.I was on National from las to sfo and we got stuck on the ramp for about 20 mins and they could not keep the cabin cool it was quite uncomfortable.  airplane

CO certainly has personal air vents on all their aircraft except for the B76's and B77's, centralized ventilation on those. The B753's have personal vents but I can't remember what the B752's have......my guess, personal vents.

Still no one can defend these "top-tier" airlines who everyone raves about! How ridiculous that they do not offer personal air vents!!!

Just for your information the items to which you are referring are not " Personal Air Vents" but are called "Punkah Louvres". The term originates from "Punkah - the Indian name given to the hand operated fan to waft the air about in Colonial Houses of India, hence the term "Punkah Wallah" - person who operates the fan.

NZ's A320 (and I'm pretty sure B733) fleet have them, can't comment on their widebody fleet though as I haven't flown them long-haul anytime in the past few years.

If we're taking a vote, I am most definitely pro-personal air vents  Smile

I love having the personal air vent. I guess it's another way for the carrier to save money by not having them installed.

You tend to find wide bodies to exclude them due to the distance of the overhead panel and the passenger.
Narrow bodied aircraft with lower lockers usually have them.

Anyone thought about savings, can you lower the pressure in the lines if all those "personal vents" are not there, does this provide any savings whatsoever?
Airlines shutdown their one engine when taxing, AA uses less water in their tanks to save weight, so is this another attempt to lower cost / obtain savings, guess the technical minds should pitch in.

On another note, it is shocking to hear that lower tiers airlines are offering something that the upper tier does not. I'm certainley, it will be revealed in due course that this feature is a waste and not necessary.

It is not shocking at all. Widebody aircraft do not have them for the reason Raffik mentioned, the ceiling is too high for most people to reach. Those vents are usually on narrow-body aircraft. since the "top-tier" carriers tend to have only widebody airplanes they don't have vents. It has nothing to do with saving money by not installing them.

Also, the IL-86 and IL-96 have the vents on the seatbacks. I also personally can't stand not having them and have been stuck on the ramp many times wishing they were there despite their germ-y reputation...
