Delhi to Bengaluru flights today & tonight
Flying today? Same-day DEL–BLR seats stay on sale until the airline’s check-in cutoff — typically 60 minutes before a domestic departure. With around 43 non-stops a day across four airlines, this is one of the easier sectors in India to fix at short notice: if the flight you wanted has gone, there is usually another a couple of hours behind it. Tonight’s live prices show in the search above, and airlines often release unsold evening seats at lower fares on the day of travel. One Bengaluru-specific caution before you book a late departure — check the arrival time, not just the departure, because a midnight landing still leaves you the long run in from Devanahalli.

About Delhi and Bengaluru
At 1,740 km and about 2h 50m in the air, DEL–BLR is one of India’s long domestic trunk sectors: national capital to tech capital, flown roughly 43 times a day. The passenger mix leans corporate — engineering and product teams, client-facing consultants, founders — alongside families and urgent medical travel.
Delhi
You leave from Indira Gandhi International (DEL), India’s busiest airport and the northern anchor of this sector. Because DEL–BLR runs across the whole day rather than in two bunched banks, missing a morning departure rarely costs you the day — which is the single most useful thing to know when you are booking in a hurry. IGI operates three passenger terminals, so confirm which one your flight actually leaves from before you set out; the inter-terminal move is not quick. Fares move fastest around the Monday-morning and Friday-evening business banks, festival windows, and Delhi’s winter fog mornings, when knock-on delays reshuffle availability across the day.
Bengaluru
You land at Kempegowda International (BLR), which sits at Devanahalli well north of the city — roughly 35–40 km out, far enough that the drive in can eat a serious fraction of the 2h 50m you just spent flying, and considerably more in evening traffic. Price that ground leg into your choice of slot: a fare that saves you a few hundred rupees but lands at 19:30 can cost two hours on the road. Weekday demand into BLR is driven by the tech sector — client visits, offsites, quarter-end travel — so if you have a morning meeting, arriving the night before is usually the safer call than a same-morning flight plus the airport run.
How Indian domestic fares move through the year
A general all-India seasonality guide — not a measurement of Delhi–Bengaluru bookings. It shows when domestic flying tends to feel affordable versus compressed by business, festive, and holiday demand.

Departure day matters more than booking day. The figures below apply a typical domestic weekday demand curve to this route’s ₹8,492 indicative baseline — they are illustrative, not measured DEL–BLR averages.
Airlines flying DEL to BLR
Four carriers fly DEL–BLR non-stop, with IndiGo running the bulk of the roughly 43 daily departures. Every non-stop is the same 2h 50m, so the real choice is slot and price rather than journey time.
| Airline | Flights/day | Direct duration | From |
|---|---|---|---|
| IndiGo (6E) | ~25 daily | ~2h 50m | ₹8,492 |
| Air India (AI) | ~10 daily | ~2h 50m | ₹9,001 |
| Akasa Air (QP) | ~5 daily | ~2h 50m | ₹8,152 |

Delhi to Bengaluru Flight Guide
Route at a glance. 1,740 km end to end, about 2h 50m in the air — long enough that DEL–BLR sits at the outer edge of what still works as a same-day return, and the reason the early-morning departure out of Delhi is the one business travellers fight over. Non-stops run through the day on IndiGo, Air India, Akasa Air and SpiceJet, all at the same 2h 50m, so airline choice is really slot choice.
When to book. Booking closer to departure generally costs more, not less: the cheap buckets go first, and on a corporate-heavy sector like this one they go early. Friday-evening and Sunday-return slots are the ones to avoid if your dates bend at all. Inside a three-day window there is no clever trick left — what helps is scanning every airline at once, taking the lowest seat still open, and locking the PNR before the bucket moves.
Seasonal pattern (all-India). Across Indian domestic flying, June, July and February are usually the calmest months, while October through January runs hot on festival and wedding travel. That is a national pattern, not a DEL–BLR measurement — we do not publish per-route monthly history, so treat it as background and use the live search for your actual dates.
Don’t forget the ground leg. Bengaluru is one of the Indian metros where the airport is genuinely far out: Kempegowda sits at Devanahalli, roughly 35–40 km north of the centre, and the transfer routinely adds an hour or more each way. Build it into the schedule before you pick between two flights an hour apart.

Tushar's note on Delhi to Bengaluru
I founded Tatkal Flights specifically for travellers booking inside the 48-hour window before departure, and Delhi to Bengaluru is one of the routes where that window matters most. On most Indian routes the cheapest fare buckets sell out first, so the closer you get to departure the higher the price usually climbs — last-minute is rarely cheaper. What we do instead is compare live fares across every airline the moment you search — including unpublished and network fares a single portal may not show — and get you the lowest seat still available, with a confirmed airline PNR in minutes. Booking inside 24–72 hours, the real win isn't a magic low price; it's a confirmed seat on the earliest workable flight without overpaying.
Two practical notes from watching this route closely: (1) Friday-evening departures on Delhi to Bengaluru tend to price noticeably higher than the Tuesday-morning departure on the same week, so if your travel date is flexible by a day or two the savings are real. (2) The "non-refundable" tag on the cheapest fare bucket has a specific definition under DGCA rules — if the airline cancels or reschedules by more than 2 hours, you're owed a full refund regardless of bucket. I keep the DGCA refund-rights guide updated each quarter for that reason.
