The movies were $7 on my flights earlier in the week, and the meals were $8.99, except the vegetarian one was $8.50. There were four fresh food choices in Y: cheese plate, turkey wrap, caprese half sandwich w/ bean salad, and the antipasto cold-cut salad.
$100 u/g for SEA-LAX is still reasonable, considering it's a full three course meal. It's transcon service on a 2.5 hour flight.
