I’ve read a number of older threads but want to check if anyone knows specifically for PE which flights / aircrafts now have the more cushioned seats? For context, I used to fly Business everywhere for work, so am used to that comfort. I did pay out of pocket for last few Biz class trips to/from HK (Aria ones). I have back and neck stiffness, so for upcoming trip having to fly PE, I want to choose the better seats. I’m still very scarred by those Olympus “curved” seats from ages ago! Can anyone tell me if the 777 aircrafts with Aria seats also the ones with new PE seats - or not necessarily? I read that some 777 have old rundown PE… so I’m confused. Or is Airbus 350 still better for PE? (Thanks!)
