This month British Airways is set to improve its range of champagnes and English sparkling wines for customers travelling in First class cabin and lounges as well as in its Club World cabin.

The airline, which serves more than two million bottles of bubbles a year, will now offer Canard-Duchêne Charles VII Champagne and Champagne Jeeper Brut Grand Rosé in First Lounges.

In First Cabin, it will serve Gusbourne, English Sparkling Wine and Lanson Rosé Champagne while Club World Cabin will get Canard-Duchêne Cuvee Léonie Brut Champagne and Champagne Besserat de Bellefon Rosé.

Castelnau champagne will continue to be served in the airline’s business class Galleries Lounges, while Laurent-Perrier’s Grand Siècle will also still be served in First.

Improved food and drink is part of the airline’s ongoing £4.5bn investment for customers. Of that, £600m is being invested in Club World, focusing on a new restaurant style dining service and a new sleep proposition with luxurious bedding by The White Company.

British Airways’ £4.5 billion investment for customers also includes the installation of WiFi and power in every seat, fitting 128 long-haul aircraft with new interiors.

Customers traveling in Club Europe will be served Castelnau champagne in quarter sized bottles.
