The booking and sale validity of this offer is from January 1 to January 31, 2009, the company said in a statement.
Its wholly-owned subsidiary JetLite will offer all domestic tickets for Rs 9 basic fare for purchases made at least 21 days in advance. The booking and sale validity for this offer is similar. All fares mentioned above are exclusive of taxes and surcharge.
Earlier this week, Jet reduced the basic fares on all its 45 domestic sectors by up to 40 per cent, bringing the Mumbai-Delhi economy class to Rs 2,000 and Bengaluru-Mumbai to Rs 1,220.
Air India and other major carriers like Kingfisher will also start booking tickets at lower prices from January 1.
While the state-owned airline has announced up to 82 per cent reduction in basic fares, Kingfisher is yet to quantify the reduction.
