I generally say business class is all about the seat and I believe that but I will also say that I love a larger pillow and 2 pillows plus the option for the gel pillow on United now in business class.
I realized what I am looking forward to least about an upcoming American Boeing 787-9 business class flight from Paris to Dallas — though that’s a netter seat — is the single tiny pillow, call me a teenage girl but I may buy a pillow in the Paris airport and toss it in Dallas on arrival.
