Just flew LAX-SEA last night.
First class- Hot food (Turkey and Halibut were the options) -- 3 courses (salad/shrimp) as starter, main course as above and dessert was a Choc. Cake of some sort.
Coach-- (took a look as a result of this thread)-- was a Cold Basket of some sort (looked like a Turkey sandwich) did not see if they had choices but that is what the first 2 rows were all eating.
So dinner is still there for both classes on the 6:48pm (think that was departure time).
Alaska had 4 flights all departing within 90 minutes (I took the first one with the First Class upgrades left (which was the last one before 7pm). All said Dinner service on the board.
