This was my first time flying upper class with the seats that made into a bed. I hate flying overnight and the seat did make it somewhat more bearable. We booked through Delta, this was a partner flight with Virgin.
The window seats do appear to be a little roomier and the layout of the middle seats have better storage on the right side of the plane than the left. I ended up swapping seats with my husband he was in 6D next to me (left side). He’s a large man and the layout was better for him. I was fine with either seat.
The service was wonderful, the only complaint I have is they would not let my husband plug in his Cpap to sleep, needless to say his experience wasn’t quite as good as mine. Delta does allow this, he has worn it before on overnight flights. The explanation was Virgin wouldn’t accept the liability of a power failure and the device stop working. Guess the don’t know Sleep Apnea can kill you and that’s why he wears the Cpap!
Hope this review priovides helpful information
