Width needed for economy seats

I think those Thomas cook 330’s offer 16.25-16.5 inch seat width.

Any non charter airline?

Yep Mytravel, Monarch, Thomas Cook and a few others all have 9 abreast in economy on their A330’s.

And for the size, see:

page 30.

Aisles 16,5 inches like MD-11. Airbus, unlike MD, does not disclose seat width, but MD offers 57,5 inches for a three-seat block and Airbus only offers 57,1 inches for 3-seat block. So, a 9 abreast A-330 is more cramped than 10 abreast MD-11.

How about 8-abreast B-767?

I dont think the A330 can genuinly go 9 abreast ! Is there a carrier that flies 9 abreast A330?

There are others I have heard of.

9 Abreast A330? I dont think the A330 can genuinly go 9 abreast ! Is there a carrier that flies 9 abreast A330? I think you meant a 7 abreast 767 and a 8 abrest 330 in which case i’ve seen 17 inch seat width for a 767 at 7 abreast as compared to 17.5 inch seat width for a A330 at 8 abreast. I seriously doubt that the A330 can go 9 abreast ! I’ve come across few nos. for various twins and they basically say –

A330/340 @ 8 abreast – 17.5 inch (i think this is the widest used currently)
A330.340 @ 7 Abreast – 19 inch (can someone clarify this please)
B767 @ 7 abreast – 17 inch
B787@ 8 abreast – 19 inch
B787@9 abreast – 17-17.5 inch (i dont know which one)
B777@10 abreast – 17.5 inch (EK config)
