Why December Flight Fare Increase Rapidly

December brings a festive travel rush across India. These factors make airfare surge:

1. Festive & Holiday Demand

Christmas week (Dec 22–27) – New Year week (Dec 28–Jan 2) These are the costliest windows for air travel in India.

2. Limited Inventory for Popular Routes

Flights to Goa, Kochi, Bengaluru, Mumbai, Delhi, Jaipur, and Bagdogra fill up first.

3. Winter Weather & Fog Delays

North India sees fog-related disruptions — airlines increase prices to manage demand.

4. High International Travel Surge

Dubai, Singapore, Thailand, Vietnam & Maldives see peak outbound flights from India.
