So I have 2 comments on this:

1) DL is pushing this as some great thing, but they are well over 10 years behind the others in the industry on this

2) I have flown Premium Economy on Eva, Virgin Atlantic, etc etc etc and the seats are pretty comfortable (similar to domestic FC) is it just me or when you look at the ad pictures that these seat cushions look EXTREMELY THIN? Like 737-900 Main Cabin thin padding?
