Well, for one flight today. It was flight 582 PDX-DEN 9:05am departure. This aircraft (5415) was substituted for a normal 757. I have never seen the interior of one of these. It's pretty darn nice. It is really weird to see how large business class is when you step into the plane from door 2L.
I guess CS was lucky today. It was a pretty light load. The back only had about 100 passengers today. So CS had to upgrade about 25 people to business. I guess it was a good day to be a Premier. The flight when out with three empty seats in first, and full in business and economy.
