Go First airline will stop flights on Wednesday and Thursday due to a severe funds shortage. Only 50 per cent of the airline's fleet is operational as it is not getting spare engines from US firm Pratt & Whitney (P&W), the carrier said in a statement. Go First said it had to stop flights "due to the ever-increasing number of failing engines supplied by P&W International Aero Engines, which has resulted in Go First having to ground 25 aircraft (equivalent to approximately 50 per cent of its Airbus A320neo aircraft fleet)."
