The partnership will see No1 operate the new brand, which could be rolled out to other lounges across the world, according to Etihad.

Following the rebrand though, The House will be styled as “home of Etihad Airways and other leading airlines” and will no longer being exclusive to Etihad passengers.

Etihad’s business, first class and Residence passengers will continue to enjoy complimentary access, as will Etihad’s gold and platinum frequent flyers and those flying with equitable status via its codeshare partners.

There will also be paid-for access for economy passengers, as well as “premium passengers of a small number of other airlines”.

Etihad said in a statement the collaboration would “allow better utilisation of the lounge and make the experience accessible to a wider market”.

Linda Celestino, Etihad vice-president guest experience and delivery, said: "This new venture will enable the airline to maintain its brand presence and, at the same time, enhance and improve the overall lounge experience for our premium guests. It will also provide an opportunity for our Economy guests to upgrade their pre-flight experience."

The House will offer a white-linen dining service and more extensive bar offering, including freshly squeezed juices and smoothies, coffees and a broader wine list, as well as cocktails and mocktails.

It will be reconfigured to create new lounge areas, bar, dining room and reading room, and will feature new showers and prayer rooms.

Phil Cameron, No1 chief executive, added: "We have worked closely with Etihad Airways over the last year to develop a new brand which complements its world-class in-flight service, to modernise the lounge interiors and to broaden the lounge’s appeal.”
