British Airways began selling thousands of items in the inventory, from drink carts and crockery for business class passengers to slippers and towels, BBC reports.
Carolina Martinoli, brand director at British Airways, says this is the first time the airline has organized such a sale.
Changing the aircrafts mix of its fleet and cabin services, plus the possibility of British Airways operating at low levels until air traffic returns, means that its depots are full of items that will never be used.
The decision comes months after the company auctioned off some of the artwork in its offices, including a work by Bridget Riley worth more than £ 1 million.
