Domestic flight tickets may get cheaper for those who opt to travel with no baggage or only with cabin baggage within the permissible weight limit. Flight operators are allowed to give concessions in ticket prices to passengers who carry no baggage or only cabin baggage, aviation watchdog Directorate General of Civil Aviation (DGCA) has said in a circular. A passenger can carry up to 7 kilograms of cabin baggage and 15 kilograms of check-in baggage. Any additional weight is chargeable.
