How early should you leave for Indira Gandhi International Airport (DEL)?
Getting to Indira Gandhi International Airport on time isn't about a single magic number — it's the sum of everything between your front door and the gate. Gate Time works backward from your boarding time and subtracts each step: the drive to DEL, parking or curbside drop-off, bag check, check-in, security, and the walk to your gate — then adds any personal buffer you want.
The result is a single, honest leave-by time for your trip out of New Delhi, India, plus a countdown and downloadable calendar reminders so you're never the person sprinting through the terminal.
A worked example: 8:00 AM boarding at DEL
Assume a domestic flight within India boarding at 8:00 AM, a 30-minute drive, short-term parking, one checked bag, a standard security lane, and a 10-minute personal buffer. Gate Time subtracts each step:
| Drive to the airport | 30 min |
| Park and walk in (short-term) | 10 min |
| Drop a checked bag | 20 min |
| Security (standard lane) | 30 min |
| Get to the gate before boarding | 15 min |
| Personal buffer | 10 min |
| Total prep before boarding | 1 h 55 min |
| Leave by | 6:05 AM |
Make that same 8:00 AM departure international and the total grows to 2 h 40 min — a leave-by time of 5:20 AM — because check-in and customs add 30 minutes and the security allowance rises from 30 to 45 minutes. Traveling with a trusted-traveler or fast-track security program instead pulls the domestic figure back to 6:20 AM.
These are the calculator's real allowances, not a rule of thumb — every number above is documented on the methodology page, and every one of them is adjustable.

Indira Gandhi International Airport (DEL) timing FAQ
How early should I leave for Indira Gandhi International Airport (DEL)?
For a domestic flight within India boarding at 8:00 AM, with a 30-minute drive, short-term parking, a checked bag and a standard security lane, Gate Time puts your leave-by time at 6:05 AM — that's 1 h 55 min of total prep. The same trip departing internationally from DEL moves it to 5:20 AM, because international check-in and customs add 30 minutes and the security allowance rises from 30 to 45 minutes. Change any of those inputs and the answer changes with it.
Is an international flight from DEL different from a domestic one?
Yes — by 45 minutes in the example above. Flights within India skip the 30-minute international check-in and customs allowance, and clear a 30-minute security estimate instead of 45 minutes. Switch the flight-type control to International and Gate Time applies both automatically.
Does a fast-track security lane change when I should leave for DEL?
It does. With a trusted-traveler or fast-track security program, Gate Time drops the security allowance from 30 minutes to 15 on a domestic flight, and from 45 to 20 on an international one — so the 6:05 AM domestic example above becomes 6:20 AM. Checking a bag pushes it the other way, adding 20 minutes for bag drop.
Should I fly from DEL or HDO instead?
Hindon Airport / Hindon Air Force Station (HDO) is the closest commercial alternative to Indira Gandhi International Airport, roughly 19 miles away. That gap is worth weighing: a longer drive to HDO can still win if it saves you a connection, and it can lose badly if it turns a 30-minute drive into a much longer one. Run both codes through Gate Time with your real drive times and compare the leave-by times directly.
What time should I leave for DEL if my drive is longer than 30 minutes?
Add the difference straight onto the leave-by time — drive time passes through the calculation one-for-one. On the 6:05 AM domestic example, an hour-long drive instead of 30 minutes moves you to 5:35 AM. Gate Time can estimate the drive to DEL from your location, and the field stays editable so you can override it with what the traffic actually looks like.
