It's nice, but the last time I flew on a competing product was when BR was still offering Evergreen Deluxe so I don't really have any actual reference for comparison.
The seat is okay, but the footrest is pretty useless. I wish the seat cushion tilted into a cradle position when you reclined, but that might just be a "me" thing. Lots of storage cubbies, which is nice.
The tray table, if you're not in a bulkhead seat, is glorious.
Meals are basically Y meals with a fancier salad and a nicer dessert. Nicer booze selection, too.
You get noise cancelling headphones and an amenity kit.
They'll also have a mid-flight snack service (it's just a sandwich).
