CDG-ATL Economy to Business OLCI Upgrade
Flying BOM-CDG-ATL. During OLCI, CDG-ATL segment shows 1600$ for an upgrade from economy to business class. Still 16+ hours for departure. I See 4 empty seats in Business class. Do these offers stay at the same price till the flight departure or does AF reduce the $ close to the departure if they couldn't sell the upgrade seats? Thanks
