An Alaska employee posted pics of the first modified 737-800 on LinkedIn earlier today. As suspected, basically looks like the refreshed -700s. however, the first class seats appear to only have new seat covers/ foam rather than being all new. They don’t have the cup holders, and can’t tell from this angle whether they have foot rests.
Hopefully the pace picks up for the remaining -800s. N559AS took nearly 3 months at GSO for the refresh.
