The Delhi High Court order allowing lessors to deregister and take possession of the 54 Go First planes has all but ended hopes of a good valuation for creditors of the defunct airline, said people with knowledge of the matter. The lack of planes means there is very little in the airline to sell as a going concern, which could derail the ongoing bankruptcy process without hopes of any revival, they said. The lenders are likely to meet on Monday to decide the future course of action.
