About Delhi Airport
Delhi’s Indira Gandhi International Airport is identified by the airport code DEL.
The airport has multiple passenger terminals, and passengers should never assume that their flight will depart from a particular terminal simply because they previously used the same airline.
Terminal allocation can vary according to flight and airline operations.
Always verify your terminal through your airline’s current flight information, ticket or official airport flight information before leaving for the airport.
Step 1: Check Your Flight and Terminal
The first step should take place before you leave home.
Check:
- Flight number
- Departure date
- Scheduled departure time
- Airline
- Delhi departure terminal
- Current flight status
- Baggage allowance
Flight timings and gates can change because of operational conditions.
If your airline provides an app, SMS or email notification service, keep your contact details updated so you can receive changes.
Step 2: Keep Your Travel Documents Ready
Your required documents depend on whether you are travelling domestically or internationally.
For Domestic Flights
Carry an identification document accepted under the applicable airline, airport and security requirements.
Your name on the booking should match the relevant identification details.
For International Flights
International passengers should normally keep the following ready:
- Valid passport
- Flight booking/ticket information
- Boarding pass where already issued
- Visa or other travel authorization, if required
- Destination-related travel documents
- Supporting documents required by the destination country
Entry requirements are determined by the destination and can change. Check them before travelling.
Step 3: Complete Web Check-In When Available
Many airlines provide online or web check-in before departure.
Depending on the airline and flight, online check-in may allow you to:
- Confirm your flight
- Select or confirm a seat
- Obtain a boarding pass
- Add certain services
- Review travel information
Web check-in does not always mean you can go directly to the boarding gate.
If you have checked baggage, you will usually still need to use the airline’s baggage-drop facility.
International passengers may also need document verification at an airline counter even when online check-in has already been completed.
Step 4: Enter the Correct Terminal
Once you reach Delhi Airport, go to the terminal shown for your flight.
Keep your travel and identification documents readily accessible.
Airport access and verification procedures can change, so follow the current instructions displayed at the terminal and directions from authorized personnel.
Avoid arriving at a different terminal and assuming you can quickly walk to the correct one.
Changing terminals can take additional time.
Step 5: Airline Check-In Counter
Passengers who have not completed online check-in, need document verification, require special assistance or need to check baggage may need to visit their airline’s counter.
At the counter, the airline may:
- Verify your booking.
- Check identification or passport.
- Verify destination documents where applicable.
- Accept checked baggage.
- Issue or confirm your boarding pass.
- Provide baggage tags.
- Direct you toward the next departure procedure.
Check-in counter allocation at Delhi Airport is operational and can change, so check airport displays after entering the terminal.
Step 6: Baggage Check-In
If you are carrying checked baggage, make sure it complies with your airline’s baggage allowance.
Baggage rules are not identical for every airline or fare.
The allowance may depend on:
- Airline
- Route
- Cabin class
- Fare type
- Frequent-flyer benefits
- Destination
- Baggage size and weight
Do not assume that baggage included on one flight will be included on another.
Before leaving home, check your airline’s current cabin and checked-baggage rules.
Baggage Tips
Remove old airline tags from previous journeys and make sure your baggage is properly closed.
Keep valuable or essential items according to applicable airline and security requirements rather than packing them carelessly in checked baggage.
Never carry a package for an unknown person.
Step 7: Security Check
After check-in and baggage drop, passengers proceed to security screening.
Follow the instructions of airport and security personnel.
You may be required to present your boarding pass and place certain belongings in trays for screening.
Items restricted in cabin baggage are governed by aviation security rules. Airlines may also impose additional restrictions.
Before travelling, check the current rules for:
- Liquids
- Batteries and power banks
- Electronic devices
- Sharp objects
- Tools
- Flammable materials
- Other restricted items
Do not rely on an old social-media post for security rules.
Step 8: Immigration for International Flights
Passengers departing India on applicable international flights proceed through immigration as part of the departure process.
Keep your passport, boarding pass and relevant travel documents ready.
An immigration officer may verify your identity and travel information according to applicable procedures.
Domestic passengers do not go through international immigration for a normal domestic journey.
Step 9: Find Your Boarding Gate
After completing the required security and immigration procedures, locate your boarding gate.
Your boarding pass may show a gate, but gate assignments can change.
Always check the airport flight-information screens for the latest information.
Do not stay far from the gate until the last minute.
Airlines can close boarding before the scheduled departure time according to their procedures.
How Early Should You Reach Delhi Airport?
There is no single arrival time that works for every passenger.
Your airline’s instructions should take priority.
International journeys generally require more processing than domestic journeys because passport, visa/document checks and immigration may be involved.
Extra time can be helpful during:
- Peak travel periods
- Holidays
- Busy morning/evening periods
- International departures
- Travel with children
- Travel with elderly passengers
- Large baggage check-in
- Special-assistance requirements
Delhi Airport’s published operational rules indicate that airline check-in counters are generally allocated well ahead of international departures, reflecting the additional processing involved.
Delhi Airport Check-In vs Security Check
Passengers sometimes confuse check-in with airport security.
They are different processes.
Check-in is primarily an airline process. It confirms the passenger’s booking and may include seat assignment, document checks and checked baggage acceptance.
Security screening is an aviation-security procedure that takes place before passengers enter the secure departure area.
Completing web check-in does not remove the requirement to pass through security.
Domestic vs International Check-In at Delhi Airport
| Process | Domestic | International |
|---|---|---|
| Airline Check-In | Yes | Yes |
| Baggage Drop | If applicable | If applicable |
| Security | Yes | Yes |
| Passport | Usually not required for normal domestic journey | Required |
| Visa Check | No | When applicable |
| Immigration | No | Yes, as applicable |
| Destination Document Check | Limited/not generally applicable | May be required |
International passengers should pay particular attention to passport validity and destination entry requirements.
DigiYatra at Delhi Airport
Eligible passengers may be able to use DigiYatra at supported airport touchpoints.
DigiYatra is designed to provide a digital passenger-processing experience using applicable identity and boarding credentials.

Travelling With Children
Families should prepare children’s required travel documents before arriving at the airport.
For international journeys, passport, visa and consent/documentation requirements can depend on destination rules and family circumstances.
Keep essential children’s items organized so that security screening is easier.
Senior Citizens and Passengers Requiring Assistance
Passengers who require wheelchair or mobility assistance should contact their airline or check the airport’s applicable assistance services.
It is better to request special assistance in advance where possible rather than waiting until boarding time.
Keep medical or mobility-related documents accessible when relevant to your journey.
