> First class passengers on an airplane are the only ones that get a full meal on most domestic air travel. How is this different?

Why go to meal comparisons instead of something more directly relevant? First class passengers get unlimited free alcohol (same with Comfort+ and above on Delta and many other airlines too), and economy class has to pay per-drink.

Part of the reason I feel like a meal analogy is not good is because it varies heavily per airline and per flight distance.
