How to Find Cheap Flights from Delhi to Trivandrum

Choosing the Right Fare Type
IndiGo launched 'Lite' cabin-bag only fares in July 2026, which are cheaper if you do not have check-in luggage.
Air India introduced 'Basic' fares in June 2026. While these still include 15 kg of check-in baggage, they do not include complimentary meals.
Terminal & Airline Updates at Delhi and Trivandrum Airports
Air India operates its domestic flights from Terminal 3 at Delhi and arrives at Terminal 1 in Trivandrum. IndiGo uses Terminals 1, 2, and 3 in Delhi, so you must check your ticket for the exact departure terminal.
Recent Airport Changes
Delhi Airport's Terminal 1 reopened in 2025 after a major expansion, shifting some domestic traffic. In Trivandrum, Air India moved its domestic operations from T2 to T1 in February 2024.
Because IndiGo's departure terminal at Delhi (DEL) varies by specific flight number and schedule, arriving at the wrong terminal can cause you to miss your flight.
Air India departs from T3. IndiGo departs from T1, T2, or T3 depending on the flight.
All domestic flights from Delhi arrive at Terminal 1, which is a dedicated domestic terminal.
Baggage Allowances for Delhi to Thiruvananthapuram Flights
Standard economy tickets on both IndiGo and Air India include 15 kg of check-in baggage and 7 kg of cabin baggage. However, both airlines now offer cheaper fares that restrict these allowances.
Understanding New Fare Types
If you book an IndiGo Lite fare, you are only permitted a 7 kg cabin bag; check-in luggage will cost extra at the airport. Air India's Basic fare retains the 15 kg check-in allowance but removes complimentary meals.
| Airline | Cabin Bag | Check-in (Standard Fare) | Lite / Cabin-only Fare | Notes |
|---|---|---|---|---|
| IndiGo | 7 kg | 15 kg | Cabin bag only | Lite fare removes check-in baggage entirely. |
| Air India | 7 kg | 15 kg | No cabin-only fare | Basic fare includes 15 kg but removes meals. |
Excess Baggage: Check the airline's official website for excess baggage policies.
Common Pitfalls on the Delhi to Kerala Route
Delhi's winter fog and Kerala's monsoons frequently cause flight delays.
Weather Disruptions
From December to February, dense winter fog in Delhi frequently disrupts morning departures. If you are travelling during these months, book an afternoon flight like IndiGo's 18:35 departure.
In Kerala, the monsoon season (June to September) and post-monsoon cyclones (October to November) can cause arrival delays at TRV.
Key Takeaways for Delhi to Trivandrum Travellers
- Terminal Confusion: Do not assume your IndiGo flight departs from T1; it could be T2 or T3.
- Winter Fog: Avoid early morning DEL departures between December and February.
Choosing Your Flight: Business, Leisure, or Connecting
