Things must be going down hill with OS and their 'Premium Cabin. They are now reconfiguring their 757's to a 3 class operation.
BA OpenSkies starting 19JUN12 is introducing re-configured Boeing 757 service, which will see the addition of Economy Class service, dubbed as “Eco Class”. “Biz Seat”, will be renamed as “Prem Plus”.
The configuration is J20 W28 Y66.
Good luck to them, hope this works. Time will tell
