Hi,

as far as I know, the rating of a seat depends on its size. At least, that is how it used to be... an ecoplus seat was 50% bigger than a standard seat, and if all other variables were the same, you could sell that ecoplus seat for 50% more.

Do the new seats work along the same lines ? Is there a direct correlation between size and rating of the new seats ?

Then it would be nice to know the "official" size of a seat. No information was given, so I decided to check some sizes myself. Unfortunately my findings are a bit confusing. A standard seat is a size 1. In other words, if a plane is certified for 100 passengers, you should be able to fit 100 standard seats in that plane. And if a seat is a size 2, you should be able to fit 50 seats of that type into that plane.

Obviously, if you try to fit private suites into a small regional jet, you should expect (big) differences. I mean, if a plane is 1.9 meter wide, and a suite is 1 meter wide, you can only fit one suite in a row and you loose a lot of space. So in my quest to find the size of a seat, I used 5 wide bodies*. The bigger the floor surface, the easier it is to use the available place.

Anyway, this is what I found

- standard seats

only in a 747-800 can you fit the number of seats promised by the manufacterer. In the 767 and the A330 you can only fit 80% of the standard seats.

- comfort

the size varies between 1.1 (747) and 1.53 (767). If the size of that seat is 1.1, you should be able to fit 318 comfort seats in a 767 instead of the 228 you can fit in now. That's a difference of 90 seats.

- recliner short

the size varies between 1.41 (747) and 1.89 (A330).If the Airbus had the same capacity as the Boeing's main deck, you would be able to install 261 seats. That's 89 seats less than a 747 can fit in the same space.

- lie flat

the size varies between 2.37 and 3.33 for the 140, and between 3.09 and 4.66 for the 160 version. For the Lie-Flat 160, that is a 50% difference between a 747 and a 767.

- full bed

seems to have the same size as the lie-flat 160. I wonder what the difference is... Martin ?

- private suite

the size varies between 5.83 (767) and 7.91 (A380). Although this is the biggest seat I checked, it seems the easiest one to fit in different planes. And surprise, surprise... the only case where the 767 comes out as the best.

Conclusions

There are big differences between different planes. And airlines with a fleet of 767's or A330's should look for a replacement. Well... 767 operators can fill their planes with private suites and hope to get enough bookings :-)

But seriously. These are the biggest planes in the game. I expect to find the same differences - and perhaps even bigger differences - when I check narrow bodies and regional jets.

So I have a question for the AS-team. Is the current cabin editor a final thing ? If so, I can start looking for the best solution for my airline. Or do you plan any changes in the coming weeks ? In that case, I better wait until the dust settles. It would be silly to replace seats or planes if things are gonna change next month ;-)

*I checked the 767-300ER, the 787, the A330-300X, the 747-800 and the A380. For the latter two I used the main deck which is the biggest deck.
