The food and art favored by Leah Chase, who was the nation’s pre-eminent Creole chef when she died in June at age 96, will live on in a restaurant that members of her family and an international hospitality group plan to open as soon as November inside the new billion-dollar terminal of Louis Armstrong New Orleans International Airport.

The idea of memorializing Ms. Chase with an airport restaurant isn’t that much of a stretch. At the New Orleans airport in 2013, the Chase family and the hospitality group, Delaware North, opened an outpost of Dooky Chase’s, the restaurant she and her husband, Edgar Dooky Chase II, ran for more than half a century in the city’s Treme neighborhood.

That outpost will close along with the old terminal this fall, although the exact date is a moving target. The new restaurant, which Ms. Chase’s family says she approved before she died, will be named Leah’s Kitchen.

Her grandson, Edgar Chase IV, grew up working at her original restaurant. After Hurricane Katrina hit in 2005, floodwaters closed Dooky Chase’s for 18 months. Ms. Chase sent him to study at Le Cordon Bleu in Paris. He returned and worked with her in the kitchen until he opened Dooky Chase’s in the airport and, later, another concession there, Dook’s Place.
