YX (Midwest Express) did that too. Real china, wine poured from full bottles, etc. Emphasis on pretty good food, and it was indeed part of their marketing.

Modestly successful through the 90's by flying niche routes without competition. ex-MCI, they were at various points our only SEA, SAT, SNA, BOS, and MKE options - and those are just the routes I remember because I flew them. Seats and service on par with a major carrier's narrowbody F throughout the cabin, with a price that generally felt like "medium-to-high Y" (in an era when discounted F was rare).

Post-9/11, they struggled. They tried jumping into competitive/leisure markets with traditional Y seating and service. Eventually they were swallowed by Frontier and none of the routes I remember so fondly are still operated by them (except maybe MKE?).
