Quick question about booking Premium Economy on a VS ticket - for Delta domestic connections sold as VS codeshares, where are you seated on a premium economy fare? (Specifically, K class.)
On Delta's own code and metal with the new A350 product, premium economy connections appear to book into first. But it's hard to tell where the VS ticket would seat you - their web site just says to contact Delta when you try to look at the seat map during a test booking, and it shows the flight as "K - Premium Economy", even on aircraft that don't have a true PE cabin like a 717 or 737.
Does K on a VS 4xxx Delta-operated flight map to a seat in economy, Comfort+ or First?
