Indira Gandhi International (DEL) splits domestic Terminal 1, regional Terminal 2 and international Terminal 3 across a large campus. Air India, British Airways and Virgin Atlantic use T3 for most long-haul; the Airport Express Metro reaches central Delhi in roughly twenty minutes when traffic is kind. Plan wider buffers in Dec–Jan VFR peaks and confirm e-visa rules before a city exit as of July 2026.

How is Delhi DEL laid out and which terminal should you use?
DEL’s passenger story is three active terminals: Terminal 1 for most domestic flights, Terminal 2 for regional and some low-cost operations, and Terminal 3 as the main international campus. They are not interchangeable — a domestic arrival in T1 and an international departure from T3 is a genuine airport change. Follow the terminal code on your boarding pass, not an old itinerary screenshot.
This DEL guide covers terminals, connection bands, layover options, Metro links, lounges, Wi-Fi and left luggage for July 2026. Delhi’s winter smog and summer heat both punish outdoor kerb time — use indoor links where you can.
Terminal 3 hosts British Airways, Virgin Atlantic and many full-service long-hauls alongside Air India’s international banks. Terminal 1 remains the domestic workhorse; Terminal 2 serves a narrower set. For stay planning see Delhi. Compare hub alternatives at Dubai DXB, Changi and Heathrow.
Figures below are illustrative planning bands as of July 2026. Terminal maps, transfer rules and fares change — confirm on the airport and operator sites for your travel day.
| Terminal | Typical airline posture (planning) | Note |
|---|---|---|
| Terminal 1 | Domestic full-service and LCC | Separate campus from T3 <!-- VERIFY --> |
| Terminal 2 | Regional / selected domestic | Confirm if your ticket cites it |
| Terminal 3 | International + Air India long-haul | Main BA/Virgin campus <!-- VERIFY --> |
| Inter-terminal | Shuttle / road links | Allow time; not a short walk |
| IGI campus | Three-terminal split | Never assume one check-in hall |
What connection time should you plan at Delhi DEL?
Protected international-to-international connections inside Terminal 3 are the intended product and can work near published minima on a calm day. T1↔T3 moves, immigration peaks and separate-ticket self-transfers need much wider comfort bands. Dec–Jan VFR season adds queue length that static MCT tables understate.
Through-checked bags on a single ticket through T3 are the calm path. Domestic-to-international or T1-to-T3 itineraries behave like campus changes — budget shuttle time, security re-clearance and peak-hour immigration.
Two-ticket itineraries that force a landside exit are fragile. Prefer protected metal when shopping flight deals. If disruption hits a qualifying UK/EU origin coupon, see flight delay compensation rights.
| Transfer shape | Planning band (July 2026) | Why it matters |
|---|---|---|
| Intl ↔ intl in T3 through-ticket | Often ~2–3 hrs comfort | MCT can be tighter; immigration peaks <!-- VERIFY --> |
| Domestic T1 → intl T3 through-ticket | Often ~3–4 hrs comfort | Campus change + queues |
| Self-transfer with bags | Often 5+ hrs preferred | Reclaim + re-check + immigration |
| Dec–Jan VFR peak days | Add contingency | Family traffic and weather <!-- VERIFY --> |
| Late-night sparse banks | Avoid tight turns | Fewer recovery options |
What can you do on a 3, 6 or 12-hour layover at Delhi DEL?
Short layovers should stay airside in Terminal 3 with food, shopping and lounge access. Six hours opens quiet rest and shower options without risking the city. Twelve hours can justify a Metro trip to central Delhi only when your passport qualifies for entry and you have honest return time through immigration and security.
Three-hour windows are for gates, lounges and light meals — not Old Delhi markets. Six hours suits Plaza Premium or airline lounge showers, left-luggage if you store a bag landside, and a calm walk through T3’s retail spine.
Twelve-hour layovers tempt a Red Fort or Connaught Place run via Airport Express Metro — viable only with confirmed entry rights. India’s e-visa and visa-on-arrival rules vary by nationality; check official sources before you plan a city exit. Transit without entry stays entirely airside.
Sleep options include airside seating, paid lounge rest and landside transit hotels linked to the campus — book overnight holds when your bank slips. Showers sit in Plaza Premium and Maharaja lounges; pay-in access helps economy travellers on long waits.
| Layover length | Realistic options | Transit visa / exit note |
|---|---|---|
| ~3 hours | Stay airside T3; lounge or food court | City exit unrealistic <!-- VERIFY --> |
| ~6 hours | Lounge shower; quiet rest; light shopping | City only if entry confirmed <!-- VERIFY --> |
| ~12 hours | Metro to central Delhi; half-day sights | E-visa / visa rules apply — verify passport <!-- VERIFY --> |
| Overnight | Transit hotel or lounge rest | Do not miss morning immigration peaks |
| Sleep / showers | Plaza Premium; Maharaja; transit hotel | Book peak-season lounge slots early |
What is the fastest way from DEL to central New Delhi?
The Delhi Airport Express Metro from Terminal 3 is usually the speed leader into New Delhi station and the central spine, running in roughly twenty minutes when service is normal. Pre-paid taxis and app cabs trade predictability for door-to-door ease. Pick by terminal, luggage and whether your hotel sits on the Metro corridor.
Follow Metro signs from T3 arrivals; the Airport Express is separate from the wider Delhi Metro network and terminates at New Delhi with selective stops. Late-night frequency thins — taxis cover the gap.
Official pre-paid taxi counters beat kerb touts. For neighbourhood planning see Delhi. T1 and T2 have their own road links — confirm which terminal you land at before you commit to a mode.
| Mode (DEL → central Delhi) | Typical time band | Typical adult fare band | Best when |
|---|---|---|---|
| Airport Express Metro (T3) | ~18–25 min to New Delhi | Often ~₹60–₹100 band <!-- VERIFY --> | Light bags; daytime service |
| Pre-paid taxi to Connaught Place | ~45–75 min traffic | Often ~₹500–₹900 band <!-- VERIFY --> | Door-to-door; heavy luggage |
| App cab / rideshare | ~40–70 min traffic | Surge-dependent | Late night; familiar apps |
| Inter-terminal shuttle + Metro | Add T1/T2 transfer time | Combined fare | Domestic arrival → city |
| Hotel car | Pre-booked fixed rate | Quoted at booking | Families; first-night fatigue |
Which lounges can you use at Delhi DEL?
Terminal 3 hosts Air India Maharaja lounges, Plaza Premium pay-in rooms and carrier contract spaces. British Airways and Virgin Atlantic passengers usually follow oneworld or individual carrier rules in T3. Eligibility depends on cabin, status, card benefits and prepaid passes — confirm before you walk.
Plaza Premium is the practical pay-in option for economy travellers with hours to kill. Maharaja lounges serve Air India cabin and status tiers. Priority Pass lists change; exclusion windows still apply.
Shower demand spikes after overnight banks from Europe — arrive early or pre-book where offered. Compare lounge access against a Metro city run only when immigration time is honestly surplus.
| Lounge type | Typical access path | Terminal note |
|---|---|---|
| Air India Maharaja | AI cabin / status | Terminal 3 <!-- VERIFY --> |
| Plaza Premium | Prepaid or walk-up | T3 international <!-- VERIFY --> |
| BA / Virgin contract | Cabin / status / invite | Follow boarding-pass terminal |
| Priority Pass | Membership + exclusions | Confirm live list <!-- VERIFY --> |
| Pay-in day pass | Airport website / desk | Peak slots sell out Dec–Jan |
Does DEL have free Wi-Fi and left-luggage storage?
DEL typically offers free Wi-Fi after a splash-page login, with workable coverage in Terminal 3 for messaging and light browsing. Left-luggage desks operate landside with per-bag daily rates. Treat both as convenience tools — immigration rules, not the storage counter, decide whether you can leave the airport.
Connect to the official airport network; captive portals can drop during terminal moves. Carry an eSIM for tethering if you need reliable uploads.
Left-luggage helps on a long Delhi day between flights. Photograph bag tags, note desk hours, and never store passports or medication.
| Service | Typical planning note (July 2026) | Tip |
|---|---|---|
| Free Wi-Fi | Splash login; speed band common | Official DEL SSID <!-- VERIFY --> |
| Paid Wi-Fi upgrade | Faster sessions on busy days | Only if you need uploads |
| Left luggage | Per bag / per day desk rates | Landside; check hours <!-- VERIFY --> |
| Luggage wrap | Optional plastic wrap desks | Airlines may still open bags |
| Porter / trolley | Paid assistance landside | Useful with T1↔T3 moves |
What should you do if your DEL flight is delayed or cancelled?
Use the operating-carrier app first for rebooking, keep boarding passes and delay timestamps, and ask about hotels when overnight disruption is covered. UK/EU compensation frameworks can attach to qualifying origin coupons even when you are standing in Delhi. Separate tickets and extraordinary circumstances weaken claims — document everything.
Start with flight delay compensation rights for the legal map, then file through your carrier with evidence. DEL fog and winter smog cancel banks; VFR peaks lengthen queues without always triggering care.
If you miss a separately ticketed onward flight, rebooking paths are weaker than on a protected through-ticket. Build buffers next time or buy a single ticket when shopping flight deals.
- Screenshot delay notices and new flight offers in the airline app
- Ask for meal or hotel care when rules require it on overnight misses
- Keep boarding passes and bag tags from the disrupted segment
- Note actual arrival time at the final destination for compensation thresholds
- Do not exit for the city until your new departure is confirmed
What is the practical bottom line for using DEL well?
Confirm T1 versus T3 before you pack, pad Dec–Jan connections generously, and use Airport Express Metro when time and entry rules allow a city run. Pre-check lounge and e-visa rights, travel with soft cabin bags on self-transfers, and keep delay evidence ready. Compare Delhi hub routings before you lock the fare.
DEL rewards protected T3 international tickets and punishes casual dual-ticket gambles across terminals. Pair with Delhi, Heathrow and Changi when routing is still flexible.
