Indigo is offering all-inclusive fares starting as low as Rs 1,662, the airline said on Friday. However, to avail the low airfares, tickets have to be booked 90 days prior to the date of travel.

There are limited seats available, IndiGo said. Under the offer, tickets from Delhi to Lucknow are available at Rs 1,662. Flight tickets on the Delhi-Mumbai route are available at Rs 2,885.

This offer is the latest in a slew of offers that airlines have been offering customers, in a bid to fight for market share in a very competitive market.

Last week, IndiGo launched a flash sale with airfares starting at Rs 1,727.

Airlines try to attract customers with special schemes for travel during the January-March and July-September quarters - traditionally considered periods of low travel demand.
