It's definitely longer, but it's kinda "bs" long. I have now had two flights on 74A upstairs when that part didn't fit properly, it's just really cheap hard plastic over nothing...underneath are hoards of wire and strips of metal that connect to the airframe. Definitely not made to be part of the "seat" (the only thing that makes you think so is that it has the same seat fabric over it). Not exactly reassuring...honestly, it's just cheap hard plastic and when it doesn't fit properly when you law down it's very awkward, because the angles of the hard plastic jab you in the face. I'm not sure what caused it to get out of shape like that, but I spent a good 30 minutes on each flight trying to make it fit back in its place but it wouldn't. So I just got more vouchers from the ISM, I'm at $700 right now...it's a ridiculous collection, primarily on the back of weird things happening in the new J and F.

Anyhow though, I wish they had made that more cushioned so it actually was a longer "seat", as opposed to fabric over hard plastic. I've taken to bringing along an extra pillow with me on 74A flights upstairs in J so I can maximize that space, because if you don't I've found it actually hurts when you lay on it. It's pretty good if you're willing to customize though, grab extra cushions, blankets, whatever I bring my own pillow,I used my coat once, if you do that then more space is pretty good.
