Delta and SkyTeam airlines have discount rates for Premium Economy labeled flights to several cities in Scandinavia from airports around the USA for travel departures April to early June, then resume again from mid-August.
As was pointed out to me in the comments section after my initial posting, these flights are not a true premium economy class on aircraft for routes I have shown. The value here is for mileage earners in SkyTeam Alliance frequent flyer programs where these tickets book in W Class for 100% to 150% flight miles in most programs besides Delta. This premium economy W class ticket price of $800 to $900 compares to tickets about $300 less for economy V class earning 25% flight miles.
Los Angeles, San Francisco and San Jose to Copenhagen, Oslo, Bergen, Stavanger, Trondheim, Gothenburg and Stockholm are priced in upper $700s to mid-$800s round trip.
Paris and Inverness, Scotland price around $900 round trip.

Barcelona and Madrid are other cities I see on Google Flights priced in $900s for Delta Premium Economy, but I was unable to find fare links from Google Flights to pull up these fares.
I did not find ticket prices anywhere near these low fares when searching Momondo.com for Premium Economy tickets.
