I'll start with the first question.
As an DL elite having booked main, it seems I was upgraded to a seat on a 767-400 that is declared to be Comfort+ but it actually looks like a Premium Select (i.e., premium eco) seat.
Is that possible or do I have the wrong seatmap? Seat is 20B, it's a flight between the West Coast and JFK.
Just curious as an aviation geek...
