Domestic air travel in India connects major cities and regional destinations across the country. For long distances — particularly routes above 800–1000 km — flying is the fastest option and comparable in total cost to an AC train berth once time is factored in.
The general process of flying is the same as anywhere: book a ticket, check in, clear security, board. What differs in India is the security process and a few operational specifics worth knowing.
When flights make sense over trains
Flying is the practical choice for long routes where the journey time saved is significant — Delhi to Chennai, Mumbai to Kolkata, or any route where overland travel takes more than 16 hours.
For medium distances of 400–800 km where a comfortable overnight train exists, the train is often the better experience — less transit time to and from airports, no cabin baggage anxiety, and you arrive rested.
Airlines
India has four main domestic airlines operating scheduled services.
IndiGo
IndiGo is India's largest airline by market share and operates the most extensive domestic route network.
Air India
Air India operates both full-service and budget (Air India Express) services on domestic routes.
Akasa Air
Akasa Air is a newer low-cost carrier. It operates on a growing number of domestic routes with a young fleet.
SpiceJet
SpiceJet operates domestic routes but has faced significant operational disruptions in recent years.
Ticket Booking
Domestic flight tickets can be booked directly on airline websites or through aggregator platforms. All major platforms accept international debit and credit cards. Direct booking avoids third-party fees and simplifies any changes or cancellations.
Aggregator platforms
Google Flights, MakeMyTrip, Cleartrip, and Ixigo list all domestic carriers and allow price comparison across airlines. Useful for route planning and comparing fares.
How far in advance to book
Domestic fares in India follow dynamic pricing. Booking 6–8 weeks in advance on popular routes gives the best fares. Festival periods — Diwali (October/November), Holi (March), and school holiday windows — see higher fares and reduced availability.
Last-minute fares on popular city-pair routes can be high. If your travel dates are flexible, mid-week flights (Tuesday, Wednesday) are generally cheaper than weekend travel.
Check-in
For domestic flights in India, all passengers must present a government-issued photo ID at check-in and at security. For foreign nationals, the required document is your passport. Carry your passport to the airport for every domestic flight.
Security Process
Indian airport security is operated by the CISF (Central Industrial Security Force) and follows a process that differs from most international airports in a few specific ways:
Boarding pass stamping
After clearing the security screening, your boarding pass is stamped by the CISF officer. This stamp is checked at the gate before boarding. Do not lose or damage your boarding pass between security and the gate.
Frisking
Physical pat-down frisking is mandatory for all passengers at Indian airports — it is not selective or random. It is gender-separated — male passengers are frisked by male officers, female passengers by female officers. This is standard procedure, not an escalated security measure.
Baggage screening
All cabin baggage goes through X-ray screening. Liquids, gels, and aerosols follow the standard 100ml rule in a clear bag. Checked baggage is also screened before check-in at some airports — you may be asked to open bags for physical inspection.
Timing
Arrive at the airport at least 2 hours before departure for domestic flights. At larger, busier airports — Chhatrapati Shivaji Maharaj International (Mumbai), Indira Gandhi International (Delhi), Kempegowda International (Bengaluru) — allow 2.5 hours during peak hours. Security queues at Indian airports can be long.
Boarding begins 45–60 minutes before departure. Gates close 15–25 minutes before departure.
DIGI Yatra
India operates a voluntary biometric boarding system called DIGI Yatra but it is currently available to Indian nationals only. Foreign nationals are not currently eligible to enroll. You will use standard check-in and boarding pass procedures.
Baggage
Cabin Baggage
The standard cabin baggage allowance on Indian domestic flights is 7 kg for one cabin bag, plus one small personal item (handbag, laptop bag, or small backpack). Limits are enforced — bags are weighed and tagged. Oversized or overweight cabin bags will incur fees.
Checked Baggage
Checked baggage allowance varies by airline, class, and fare type. You must check it with the specific airline you are using for travel. Excess baggage is charged per kilogram. Calculate your baggage needs before booking and add the appropriate allowance upfront.
Prohibited Items
Standard international aviation security rules apply. You can check these items at airindia.com or goindigo.in
