Indian low-cost carrier IndiGo launched two new domestic services on 30 May.
These are four times weekly Chennai-Kochi and daily Mumbai-Jammu services, the airline says.
It also raised the frequencies of six services on the same date.
The airline also doubled its Mumbai-Srinagar and Jammu-Srinagar services to twice daily and added three weekly services on the Chennai-Trivandrum and Mumbai-Trivandrum routes. Four weekly services were also added on the Chennai-Kochi and Mumbai-Kochi routes.
On the international front, IndiGo plans to raise its Mumbai-Muscat service to daily from four times weekly on 15 June, it adds.
Innovata schedules show that IndiGo competes with SpiceJet on the Chennai-Kochi and Mumbai-Jammu routes.
