Im looking for a little bit of help figuring out which carrier to use on this route in a month or so. The reason Im not going with 9W straight away is that Im not too much a fan of herringbone seats. Ive flown on the AC J seat that is fairly similar to 9W and found it narrow around the shoulders when lying down. Is the 9W seat any different? My other options are IT J (I used to be an IT fan, but, their reputation is in the pits recently) or AI F. Any recommendations?
