No decision has yet been arrived at on these matters but the airline is actively considering the options, Air India sources said here.
The national carrier, which has already stopped serving hot meals on domestic flights of less than 90 minutes, could decide not to serve any food on its services which are less than one hour, the sources said.
Currently, passengers pay for having food on no-frill carriers IndiGo, Spicejet and GoAir, while full service airlines Air India and Jet Airways provide complimentary meals on all flights.
Globally, financial pressures have inspired some airlines to either begin charging for meals or abandon them altogether in favour of small snacks.

By not serving meals on short-haul sectors, Air India can achieve a faster turnaround of an aircraft, which would remain cleaner and have lesser weight on a flight, the sources said, adding that such a move would reduce costs in a major way.
On the charges for preferred seats, the sources said this was being considered but a decision would be taken only after there is some clarity on the rules governing 'unbundling' of such services by the aviation regulator DGCA.
Air India Express, the budget arm of the national carrier, had earlier announced charging for preferred seats but withdrew the proposal in face of opposition by passengers. It has already slashed the weight of free baggage allowance from 20 kg to 15 kg.
