If service is the same as AA--then expect bev/hot lunch service on ORD late a.m. departure in Y, and then "snack" 1.5 hours out. AA snack was nothing more than bag of pretzels, cheese dip and a pack of crackers along with a chocolate mint.
Returning out of HNL with late afternoon/early eve. dept--bev/hot dinner service and then "snack" 1.5 hours out of ORD. In AA case "snack" is a stretching a bit. As the snack on the return was orange juice.
