India’s aviation market is one of the busiest and fastest-growing in the world. With a vast network of routes connecting major metros and smaller cities, flying is often the most convenient way to travel. However, with numerous airlines and varying rules, it can be confusing for a first-timer. This guide breaks down everything you need to know about booking cheap flights, navigating the check-in process, and understanding the key players in Indian domestic air travel.

The Major Airlines in India
The Indian sky is dominated by several key airlines, each catering to different needs.
- IndiGo: The largest carrier in India, IndiGo Airlines is known for its punctuality and extensive network. Finding a good IndiGo flight is easy on almost any domestic route.
- Air India: The national flag carrier, now part of the Tata Group. Air India offers a full-service experience and is a member of the Star Alliance.
- Vistara: Another full-service carrier from the Tata Group, Vistara is known for its premium service and excellent cabins.
- SpiceJet: A popular low-cost carrier that often offers competitive fares.
- Air India Express: Previously focused on international budget routes, Air India Express is expanding its domestic network.
- Alliance Air: Primarily serves regional and Tier-2 city routes, connecting smaller towns across the country.
Booking Your Flight: Finding the Best Deals
The first step is always booking your ticket. To find the cheapest flight possible, it’s best to use online travel agencies (OTAs) to compare prices across all airlines. Many travelers use platforms like HappyEasyGo or Udchalo Flight services to find deals. Always keep an eye out for a HappyEasyGo coupon to save even more.
A popular route like a Mumbai to Kolkata flight can have dozens of options, so comparing is key.
Before You Fly: The All-Important Web Check-In
In India, it is mandatory for all passengers to perform web check-in before arriving at the airport. This is a critical step.
- How it Works: Typically 24-48 hours before your flight, you will receive an email from the airline. You must visit their website and enter your PNR (Passenger Name Record) number and last name to select your seat and get your boarding pass.
- Airline-Specific Check-in: Each airline has its own portal. You will need to search for “SpiceJet web check-in,” “Air India web check-in,” or “IndiGo” check-in depending on who you are flying with.
- Baggage: During web check-in, SpiceJet and other airlines will ask you to declare that you are not carrying any prohibited items in your checked or cabin baggage.
After completing check-in, your Air India boarding pass or IndiGo pass will be sent to your email.

Checking Your Booking and Flight Status
After booking, you can always check on your reservation.
- PNR Status: Your PNR is a unique code for your booking. You can perform a flight PNR status check on the airline’s website to confirm your ticket. For example, you can search for “SpiceJet PNR check” to go directly to their portal.
- Flight Status: On the day of your travel, it’s wise to check your real-time flight status. All major airlines, like Air India, have a flight status tracker on their website. This is crucial for checking for delays, especially when traveling to airports like Bagdogra or Darbhanga during monsoon season. The IndiGo flight status tracker is known for being very accurate.
At the Airport and Customer Care
If you run into any issues, you’ll need to contact the airline. Having the IndiGo customer care number or SpiceJet customer care number saved can be very helpful. If you booked through an agency, you might need the HappyEasyGo customer care details instead.
For those interested in the industry, airlines are also major employers. An Air India career or IndiGo career can be an exciting path for aviation enthusiasts.
Conclusion
Domestic air travel in India is efficient and accessible. By understanding the key airlines, remembering to perform your mandatory web check-in, and keeping an eye on your flight status, you can ensure a smooth and hassle-free journey from booking to arrival.
