It is huge. Seriously. If you’ve ever landed at Indira Gandhi International Airport Delhi, you know that walk from the gate to immigration feels like a literal marathon. You're dragging a carry-on, your legs are cramped from a ten-hour flight, and the carpet—that famous, polarizing T3 carpet—seems to go on forever. Most people think of DEL as just a transit stop, but honestly, it’s a city in itself. It handles over 70 million passengers a year. That is a staggering amount of human movement through a single patch of land in Palam.
Navigating it shouldn't feel like a survival challenge.
Most travelers make the same three mistakes. They underestimate the transfer time between Terminal 1 and Terminal 3. They forget to download DigiYatra. They don't realize that the food court in the domestic pier is ten times better than the ones near the gates. If you're flying into or out of the capital, you need a strategy. Delhi's air is thick, the crowds are dense, but the systems actually work remarkably well if you know which lever to pull.
The Terminal Trap: Why IGI Airport Delhi Is So Spread Out
Let's clear something up. Terminal 1 and Terminal 3 are not neighbors. Not even close. If your ticket says T1 but you tell your Uber driver "Delhi Airport," they might drop you at T3 by default because it’s the flagship. You’ll be stuck in a 20-minute (or 40-minute in Delhi traffic) backtrack. T1 is the low-cost carrier hub, mostly housing IndiGo and SpiceJet's domestic legs. It’s been under massive renovation to expand capacity, but it still feels a bit more chaotic than the sleek glass-and-steel vibe of T3.
Then there’s Terminal 2. It’s the middle child. Often forgotten, but actually quite efficient because it's smaller. It’s a short walk from T3, which is a lifesaver if you have a tight connection.
T3 is where the international magic happens. It’s the world’s 10th largest terminal. Think about that. When it opened in 2010 for the Commonwealth Games, it changed the game for Indian aviation. It’s got the "Mudras"—those giant hand gestures on the wall at immigration—that everyone takes photos of. But here’s a tip: don’t stop to take the photo right at the top of the escalator. Keep moving. There are more hands further down where the line is shorter.

DigiYatra is the Only Way to Travel Now
If you are an Indian citizen or have a phone number linked to Aadhaar, and you aren't using DigiYatra at Indira Gandhi International Airport Delhi, you are basically choosing to suffer. I’ve seen the general security line snake around the building while the DigiYatra gate has... maybe two people?
Basically, it uses facial recognition. You scan your face, it validates your boarding pass, and the electronic gates pop open. It’s seamless. It’s techy. It actually works. For a while, people were skeptical about privacy, but the convenience factor has completely won out. You can save roughly 30 to 45 minutes during peak hours (like the 5:00 AM domestic rush) just by having that app set up before you reach the pavement.
Layover Survival and the Lounge Situation
Layovers in Delhi can be brutal if you're stuck in the plastic chairs.
The Plaza Premium lounges are the standard go-to, but they get packed. Honestly, sometimes it’s hard to find a seat. If you have a high-end credit card, check for the Encalm Lounges. They’ve taken over much of the lounge operations at T3. The food is decent—usually a mix of butter chicken, dal makhani, and some surprisingly good pasta—but the real value is the shower. If you've just come off a long-haul flight from London or New York, paying for a shower at the lounge or the Encalm Transit Hotel is the best money you’ll ever spend.
Wait. Don't want to pay for a lounge?

Head to the "Snooze" pods. They are these little oxygen-rich sleeping chambers in T3. You can rent them by the hour. It’s way better than trying to curl up near a charging station while an announcement blares about a "final call for passenger Sharma" every five minutes.
Getting to the City (The Metro vs. The App)
You have three real choices when you exit the arrivals hall at Indira Gandhi International Airport Delhi.
- The Delhi Airport Metro Express: This is the gold standard. It’s clean, it’s fast (20 minutes to New Delhi Railway Station), and it has air conditioning that actually works. If you are staying in Connaught Place or North Delhi, don't even look at a taxi. Take the orange line.
- Uber/Ola: There are dedicated pickup zones. Do not let the "touts" inside the terminal convince you to take a private cab. They will overcharge you. Follow the signs to the multi-level car park. The Uber zone in T3 is on the top floor. It can be a bit of a trek, but the pricing is regulated.
- BluSmart: If you want a cleaner, electric car and don't mind booking in advance, BluSmart is the local favorite. They don't cancel on you. That is a huge deal in Delhi.
Food, Shopping, and the Duty-Free Myth
Is the Duty-Free at Delhi Airport actually a deal? Sorta. For liquor, it’s actually one of the better-priced shops in Asia, often beating Singapore or Dubai on specific labels of Scotch. For electronics? Skip it. You’ll find better deals on Amazon or at Croma in the city.
For food, I always tell people to skip the first fast-food joint they see. If you are in T3 Domestic, walk further in. There’s a wide range of stuff from Jamie’s Italian to local spots like Karim's (yes, the famous Old Delhi Mughlai spot has an outlet here). It's not quite as good as the original in the shadow of Jama Masjid, but for airport food, it’s top-tier.
Realities of the "Delhi Belly" and Health at DEL
Let's be real for a second. Travelers are often terrified of getting sick. The airport water stations (Piau) are generally safe and use high-grade filtration, but if you’re worried, stick to bottled water. The airport medical facility is run by Medanta. It’s a world-class hospital group. If you feel faint or have an issue, their clinic in T3 is actually better equipped than many small-town hospitals.

Moving Between Terminals: A Warning
I cannot stress this enough: there is a shuttle bus, but it requires you to go to a specific counter to get a coupon. If you have an inter-terminal transfer (like coming from an international flight at T3 and moving to a domestic flight at T1), give yourself at least three hours. Four is safer. The shuttle has to navigate the same public roads as everyone else, and Delhi traffic is legendary for its unpredictability.
One time, a friend thought a two-hour layover was enough to get from T3 to T1. They spent 50 minutes just waiting for the bus and getting through the security check at the new terminal. They missed the flight. Don't be that person.
The Seasonal Chaos: Fog and Smog
If you are traveling through Indira Gandhi International Airport Delhi between December and February, you are at the mercy of the weather. Delhi’s winter fog is thick. While T3 has CAT III-B landing systems—which basically means planes can land in almost zero visibility—it doesn't mean they can take off easily if the taxiways are clogged.
Delays during "Fog Season" ripple through the whole country. Check your flight status before you even leave your hotel. If the "visibility" numbers are low, expect a wait.
Actionable Advice for Your Next Visit
- Download the DigiYatra App: Do it at home. Register your face. Upload your ID. It turns a 30-minute security wait into a 2-minute breeze.
- Book BluSmart for Pickups: Download the app a day before. You book a slot, the driver is there, and the cars are electric and silent. No haggling.
- Locate the "Secret" Seating: In T3, the areas near the far gates (high numbers) are usually much quieter than the central hub. If you have an hour, walk 10 minutes toward the end of the pier for some peace.
- Currency Exchange: Avoid doing large amounts at the airport. The rates are notoriously poor. Change just enough for a taxi (around 1000-2000 Rupees) and find a local "Money Changer" in the city for the rest.
- T1/T3 Check: Double-check your airline’s terminal. Indigo, for example, operates out of both. Your boarding pass is the only truth—don't trust where you flew into last time.
