AirAsia India, which entered the budget segment space with its first flight to Goa from Bangalore on June 12 is now all set to launch its flight services on the second route, Bangalore-Chennai-Bangalore from coming Thursday. Besides, it has already announced to add Kochi in its network from next month.
SpiceJet had earlier last week announced a monsoon scheme starting from Rs 1,999 for its flight from eight South Indian cities-- Bengaluru, Chennai, Coimbatore, Hyderabad, Kochi, Kozhikode, Mysore and Visakhapatnam.
Following the entry of the Malaysian budget carrier AirAsia in the domestic market through its subsidiary AirAsia India, its rivals IndiGo and SpiceJet have been trying to match its low-fares with one after another promotional offers to wean away the customers to their sides.
Before rolling out the monsoon offer, SpiceJet had come out with a promotional all-inclusive ticket offer starting from Rs 2,999 for a one-way journey on domestic routes, primarily from Tier-II cities.
