New Delhi/Mumbai: A proposed infusion of Rs 1,000 crore into Jet Airways may prove to be "too little too late" to save the airline as it might require at least '10,000 crore to stay afloat, industry observers said on Friday.

According to industry estimates, Jet's total debt of Rs 8,000 crore in addition to payables such as vendors' dues worth Rs 15,000 crore, would require something more substantial than just '1,000 crore that a consortium of public sector banks might muster up.
