My last few international (North America -> Europe) didn't have meals. Booze? Yes. Snacks? Yes. Meals? No. I actually plan on traveling first class next time because of this.
Have you actually checked the price differential between coach and first class? It's like two orders of magnitude. Might be better off stopping at Mickey Dees at JFK before boarding.
Norwegian is the only carrier I know with optional meal service.
If you're the carrier - it's bad business to have hangry passengers.
That said, we all expect more of international flights, and this is a really disappointing data point to learn of.
