Delhi Airport: You Need Your Ticket Just to Walk In

Getting there, at a glance

Amenities, at a glance

Indira Gandhi International Airport (IATA: DEL) is India’s busiest airport and one of the busiest in the world, serving more than 70 million passengers a year as the country’s primary gateway. It sits about 16 km (10 mi) southwest of central Delhi.

Overview

DEL operates three terminals, with Terminal 3 standing out as one of the largest airport terminal buildings in the world when it opened for the 2010 Commonwealth Games. A key thing that catches first-time visitors off guard: unlike most airports worldwide, you cannot enter the terminal building at all without a valid ticket and government-issued photo ID — security checks happen at the entrance gate, not just before your gate. The Airports Authority of India reported 77.8 million passengers for DEL in 2024, a 7.8% increase on 2023 that made it India’s busiest airport and the world’s ninth busiest.

Terminals

• Terminal 1: Primarily domestic flights, including IndiGo’s major domestic operation.
• Terminal 2: A mix of domestic flights.
• Terminal 3: The main international terminal and Air India’s primary hub, one of the largest single terminal buildings in the world.

Always confirm your terminal in advance, since Delhi’s terminals are far enough apart that a same-airport transfer between them takes real time.

Airlines

IndiGo, India’s largest airline by market share, operates a major hub at DEL with an extensive domestic network across the country. Air India, the flag carrier, anchors Terminal 3 with both domestic and international long-haul routes. Together they make DEL the best-connected airport for travel within India and one of the key gateways between South Asia and the rest of the world.

How to Get There

• Delhi Airport Metro Express: ₹60–150 depending on distance, the fastest way into the city at about 20 minutes to New Delhi Railway Station on the dedicated Orange Line.
• Prepaid taxi: ₹400–600 to central Delhi via the official prepaid taxi counter inside the terminal — use this counter specifically rather than accepting offers from anyone approaching you outside, about 45–60 minutes depending on traffic.
• Uber / Ola: Generally comparable in price to a prepaid taxi, about 45–60 minutes — both apps are widely used and reliable in Delhi.

Prices above are indicative and can change — always check current fares with the Delhi Airport Metro Express or your ride-hailing app.

Getting Through Security and Passport Control

• Domestic flights: Security only, but remember you’ll also pass a document check just to enter the terminal. Typically 20–30 minutes for the actual security screening off-peak, up to 35–50 minutes during busy periods.
• International flights: Security plus passport control. Typically 30–45 minutes off-peak, up to 50–75 minutes during peak international departure banks — DEL handles a very high volume of both domestic and international travelers, so lines can build quickly.
• Have your ticket/boarding pass and a valid photo ID ready before you even reach the terminal doors — you won’t get past the entrance gate without them, regardless of how early you arrive.

Parking

DEL has ample parking at all three terminals, with clear signage for both short- and long-stay options. Pre-booking online is generally cheaper than the walk-up rate.

Wifi

Free wifi is available across the terminals with a time-limited free session; a local SIM or eSIM with an Indian data plan is a reliable backup, especially useful for ride-hailing apps.

Best Times to Arrive

• Domestic flights: Arrive 2 hours before departure — remember to factor in the terminal-entrance document check as part of that buffer, not just the security line itself.
• International flights: Arrive 3 hours ahead, especially for late-night departures, which are common on long-haul routes from Delhi.
• Delhi’s traffic can be unpredictable and, in winter, dense fog can cause real delays to both road transport and flights themselves — build in extra buffer during December and January specifically.

Where to Eat

DEL has a strong selection of regional Indian cuisine — from South Indian dosas to North Indian street food favorites — alongside international chains, spread across all three terminals with the widest selection in Terminal 3. At the nearby Roseate House, a restaurant genuinely named DEL — after the airport’s own code — serves a world-cuisine bistro menu with live cooking counters, alongside Kheer for North Indian classics.

Airport Hotel

Roseate House New Delhi sits minutes from the terminal in the Aerocity hotel district, built specifically to serve IGI Airport. Beyond DEL and Kheer, it has Tara, a rooftop lounge doing Japanese small plates, and Roasted by Roseate, a dedicated tea lounge — a genuinely varied set of options for a long layover.

Lounges

• The Air India Maharaja Lounge in Terminal 3 is available for eligible business/first class passengers, elite status holders, or paid access.
• Several Priority Pass-affiliated lounges are also available across the terminals.

Duty-Free Shopping

DEL’s duty-free zone includes Indian specialties — spices, textiles, and jewelry — alongside the usual international fashion, cosmetics, and electronics brands, making it a solid last stop for India-specific souvenirs.

• Delhi Airport Metro Express — routes and fares.

Long Layover Tips

• With 6+ hours and a visa situation permitting entry (India offers e-visa on arrival for many nationalities — check current rules before flying), the Metro Express makes central Delhi’s historic sites reachable in about 20 minutes.
• If staying airside, Terminal 3 has by far the best mix of lounges, dining, and shopping for a long international wait.
• Since you need a valid ticket just to get inside, anyone picking you up or dropping you off has to wait outside the terminal building — plan the meeting point accordingly rather than expecting a curbside terminal entrance.
