With a rehab plan for Air India proving to be a fraught task, a proposal to undo the decision to forge Air India and Indian Airlines into a single entity has been mooted by the finance ministry. The ministry, which has to foot the bill for any revival package, is understood to be increasingly nervous over the viability of bailout plans for the floundering carrier.

In spite of demerger, it's believed, the domestic and international operations of Air India would continue to function as separate units.
