Apparently US is launching premium meals for international flights. I know UA has tried this on certain routes, and ANA offers one as well for around $100.
US's is much more affordable at $19.99 with a glass of wine included. I consider US's BOB meals the best in the USA so this might not be too bad of a value.
The standard two free meals will still be provided.
