Cheapest Way From Delhi to Shillong: Train vs Flight

Browse more guides: India travel | Asia destinations

I've done the Delhi to Shillong trip four times now, twice for work and twice for pleasure, and I keep getting the same question from friends planning their first northeast trip: should I fly or take the train? The honest answer is neither answer is wrong, but the wallet outcome and the time you give up look very different once you stop comparing fares on price-comparison sites and start adding the awkward last leg from Guwahati. Shillong itself doesn't have a commercial airport, so every plan ends with a 110 km road transfer that nobody seems to mention until you're already standing at Guwahati airport with luggage.

This is my full breakdown of what each option actually costs, what each one feels like, and which one I tell people to pick depending on how their week looks. I'll keep prices in real INR ranges I've paid or seen quoted on IRCTC and IndiGo within the last booking cycle.

Why Shillong Has No Airport And Why That Matters

Shillong does technically have a small airfield called Shillong Airport at Umroi, about 30 km outside town, but commercial flights to it are sparse, often canceled, and almost never the cheapest option. AlliedNorth aviation runs occasional ATR services from Kolkata, and a handful of routes from Guwahati get scheduled and then quietly dropped. For practical purposes, treat Shillong as a city you reach by road from Guwahati. Once I accepted that, my planning became much simpler. The real question isn't Delhi to Shillong, it's Delhi to Guwahati, plus the Guwahati to Shillong leg layered on top.

Guwahati on the other hand is the busiest air and rail hub in northeast India. But the airport, Lokpriya Gopinath Bordoloi International, sits about 20 km from the city center, and the railway station, Guwahati Junction, is right in the middle of Paltan Bazaar. Both connect well to NH-6, the highway that climbs up into the Khasi Hills toward Shillong.

If you want context on the broader region before booking, my 10-day northeast India trip planner walks through how Shillong fits with Kaziranga, Cherrapunji, and Tawang.

Option 1: Flight Delhi To Guwahati Plus Road Transfer

This is the option most people pick once they see the time math, and it's what I do whenever I've less than four free days. From Delhi T3 to Guwahati Lokpriya Gopinath Bordoloi airport is roughly 2.5 hours of flying. So indiGo runs the most slots on this sector, with morning departures around 6.20 am and 9.40 am being the fares I keep finding cheapest. Air India has fewer slots but sometimes undercuts IndiGo if you book three weeks out.

Real fare ranges I've seen, one way:

IndiGo DEL to GAU, 2.5 hours, INR 4,500 to 9,500 in low season, climbing to INR 10,500 to 12,000 around Durga Puja and Christmas
Air India DEL to GAU, INR 6,000 to 10,500, with the Maharaja loyalty points sometimes shaving 8 to 10 percent off

Once you land at Guwahati airport, the airport-to-Shillong leg is where people get blindsided. The fixed-rate Meghalaya Tourism Corporation taxi counter inside the arrivals hall quotes INR 1,800 to 2,500 for a sedan that fits four people plus luggage. That comes out to INR 450 to 625 per person if you're sharing with three friends, which is reasonable. But solo travelers get hit harder, since the same INR 2,500 sits on one card.

If you want the budget version, walk out of the airport, take a INR 250 prepaid taxi or a INR 30 city bus to Paltan Bazaar in central Guwahati, and find the shared sumo stand near the Meghalaya Transport office. Tata Sumo and Bolero shared rides run all day until about 5 pm, charge INR 350 per seat, and leave when full, usually within 20 minutes. The drive takes around 3.5 hours, including a tea break at Nongpoh halfway up the hill.

Total for this option:

Sole booker, sedan taxi: INR 5,000 + INR 2,500 = INR 7,500 to INR 12,000 + INR 2,500 = INR 14,500
Group of four splitting taxi: INR 5,000 + INR 625 = INR 5,625 to INR 12,000 + INR 625 = INR 12,625 per person
Solo, shared sumo: INR 5,000 + INR 350 = INR 5,350 to INR 12,000 + INR 350 = INR 12,350
Total time door to door: 6 hours, give or take an hour for traffic on the Guwahati ring road

I've flown the early IndiGo and been sipping kwai at Police Bazaar in Shillong by 1.30 pm the same day. That's hard to beat.

Option 2: Sleeper Train Delhi To Guwahati Plus Road Transfer

This is the option I used on my very first trip, when I was a student with a research stipend and 35 hours felt like a fair trade for saving INR 6,000. The Indian Railways operates several long-haul trains on the Delhi to Guwahati corridor, and the route still feels like a rite of passage for budget travelers heading northeast. Real options:

Train 12423 / 12424 Dibrugarh Rajdhani Express, daily, Delhi to Guwahati in around 28 hours 30 minutes. This is the fastest option and runs only AC classes. 3AC is roughly INR 3,000 to 3,500, 2AC INR 4,200 to 4,800, 1AC INR 7,200 plus. Catering is included, which I count as a hidden saving of about INR 400.
Train 14055 Brahmaputra Mail, daily from Delhi (Old Delhi station, not New Delhi), Delhi to Guwahati in around 31 to 32 hours. Sleeper class is INR 850 to 1,000 if booked under the general quota, 3AC INR 2,200 to 2,600, 2AC INR 3,200 to 3,800. Food isn't included.
Train 12506 North East Express, runs Anand Vihar to Guwahati in around 30 hours, similar fare bands to Brahmaputra Mail.
Train 15910 Avadh Assam Express, runs Lalgarh to Dibrugarh via Delhi area, around 34 hours to Guwahati but cheap, with sleeper near INR 800 to 950.

Add the Guwahati-to-Shillong road leg as before, INR 350 shared sumo or INR 1,800 to 2,500 taxi.

Total cost ranges:

Sleeper class plus shared sumo: INR 850 + INR 350 = INR 1,200 to INR 1,800 + INR 350 = INR 2,150
3AC plus shared sumo: INR 2,200 + INR 350 = INR 2,550 to INR 3,500 + INR 350 = INR 3,850
2AC plus airport-style taxi: INR 3,200 + INR 1,800 = INR 5,000 to INR 4,800 + INR 2,500 = INR 7,300
Rajdhani 3AC plus shared sumo: INR 3,000 + INR 350 = INR 3,350 to INR 3,500 + INR 350 = INR 3,850
Total time door to door: 30 to 35 hours

The headline INR 1,400 figure assumes you grab a tatkal sleeper berth and split a shared sumo. I've done this exact combo at INR 1,420 total, which is genuinely the rock-bottom legal way to get from Delhi to Shillong. It also wrecks your back if you're over thirty.

For more cheap-trip math, my round-up of budget travel destinations in India covers similar fare logic for other northeast and southern routes.

Option 3: Combo Strategy, Train One Way Plus Flight Back

This is what I now recommend to almost everyone who asks. The trick is that one-way flights and one-way trains are priced separately, and you can save money and sanity by mixing them.

The best combo I've run:

Delhi to Guwahati on Brahmaputra Mail in 3AC, INR 2,400, leaving Old Delhi around 11.45 pm so the long sit happens overnight
Three or four nights in Shillong and Cherrapunji
Guwahati back to Delhi on a midweek IndiGo flight, INR 4,800 booked three weeks out

Total transport: INR 7,200 plus the Guwahati-Shillong taxi legs at around INR 700 combined, so roughly INR 7,900 round trip. Compare that to round-trip flights at INR 11,000 to 18,000 and you keep INR 4,000 to 10,000 in your pocket without ever sitting on a sleeper berth on the return when you're tired and dirty from the hills.

Real Comparison Table

The numbers below are per person, one way, Delhi to Shillong door to door, current INR fares.

Route	Total Time	Cost INR	Pros	Cons
IndiGo DEL-GAU and shared sumo	6 h	5,000 to 13,500	Fastest, daily slots, predictable	Solo taxi at GAU is pricey if you skip the sumo
Air India DEL-GAU and airport taxi	6 h	6,500 to 13,000	Maharaja points, full service	Fewer flights, often slightly higher base
Direct charter or Shillong Umroi flight	5 h	18,000 to 28,000	Lands closest to town	Frequent cancellations, almost never worth it
12423 Rajdhani 3AC and sumo	31 h	3,350 to 3,850	Catering included, single AC train	AC only, sells out three weeks ahead
14055 Brahmaputra Mail sleeper and sumo	35 h	1,200 to 2,150	Cheapest legal option	No food, no AC, 35 hours is brutal
14055 Brahmaputra Mail 3AC and sumo	33 h	2,550 to 2,950	Sweet spot for budget travelers	Old Delhi station is chaotic at boarding
Train one way and flight back	36 h then 6 h	7,500 to 9,000 round trip	Best total cost, only one painful leg	Needs separate bookings, forex of patience

What I Actually Paid On My Last Trip

For my October 2025 trip I booked the following:

IndiGo 6E 2519 DEL to GAU, 6.20 am departure, INR 5,840 booked 18 days out
Prepaid sedan taxi from Guwahati airport to Shillong via NH-6, INR 2,200 split with three friends, INR 550 each
Total Delhi to Police Bazaar Shillong, door to door, 5 hours 45 minutes, INR 6,390

For the return I deliberately took:

Train 14055 Brahmaputra Mail Guwahati to Old Delhi, 3AC lower berth, INR 2,355
Shared sumo from Police Bazaar Shillong to Paltan Bazaar Guwahati the previous afternoon, INR 350
Total Shillong to Delhi, INR 2,705, in around 36 hours of which 31 was on the train

The combo total was INR 9,095 for the round trip, which is roughly INR 4,500 cheaper than the round-trip-flight version my colleague booked.

ILP And Permits, What You Do Not Need

A small note that saves people stress: you don't need an Inner Line Permit for Meghalaya. Shillong, Cherrapunji, Mawlynnong, Dawki, Mawsynram, all of it's open to Indian and most foreign tourists with no special paperwork. The state asks foreign nationals to register at hotels, which the hotel does for you anyway. Compare this to Arunachal Pradesh, Nagaland, and Mizoram, which all do require ILPs.

If you're nervous about regional safety before booking, I wrote a candid piece on travel warnings and the most dangerous place in India that puts northeast risk in perspective. Spoiler, Shillong is one of the safer state capitals.

When To Fly And When To Take The Train

I split this question by trip length:

Trip is 3 to 4 days total: fly both ways. The 60 to 70 hours you save on a train round trip is more than half your usable time.
Trip is 5 to 7 days: fly out, train back, or vice versa. The combo saves INR 4,000 to 6,000 and you only spend one long stretch on rails.
Trip is 8 days or more: train both ways is a real option, especially if you're a student or you genuinely enjoy long trains. The savings cross INR 8,000.
You're over 50 or have a back condition: just fly. The Brahmaputra Mail bunks are unforgiving.
You're traveling with kids under 8: fly. The energy management on a 32-hour train with small children is a separate skill that I've not mastered.

For a longer northeast itinerary I've used this structure inside a one-week February India plan, since Shillong weather in February is dry, cool, and pleasant.

Booking Windows That Actually Save Money

Train tatkal opens 24 hours before departure for sleeper and AC classes. And for the Brahmaputra Mail and Rajdhani, 3AC tatkal goes within the first 90 seconds. If you can book the regular quota 60 days out you'll pay 15 to 25 percent less than tatkal.

Flights to Guwahati are most volatile around three windows, the second week of June for the monsoon rush, the last week of October for Durga Puja, and the third week of December. Outside those, IndiGo prices for the DEL-GAU sector are usually best 21 to 28 days before departure. I've rarely found last-minute fares under INR 8,000 on this route.

If you live in Lucknow or are flying through it, I keep the 2-day Lucknow itinerary updated for stopover travelers.

Hidden Costs Nobody Lists

A few line items I always now budget for, because they keep adding up:

Bag check at Guwahati railway station cloak room if you go shopping in Paltan Bazaar before the sumo: INR 30 per bag for 6 hours
Toll plazas on NH-6 between Guwahati and Shillong: drivers usually include this in fixed-rate quotes, but shared sumo splits it occasionally, INR 90 to 120
Tea and momo break at Nongpoh: INR 80 to 150
Late evening surcharge if you book a Guwahati to Shillong taxi after 5 pm: drivers add INR 300 to 500 because they won't make it back in daylight

For comparison with another long Indian transport benchmark, my 7-day Kerala itinerary and the low-budget destinations list both follow the same fly-out, train-back math.

Safety, Comfort, And The Honest Trade

The Brahmaputra Mail passes through some of the more remote rail corridors in India, especially after Katihar through New Bongaigaon. Theft of unattended luggage is the main risk, not personal safety. Always chain your bag to the lower berth handle, don't leave a phone charging on the side panel overnight, and book the side lower if you're a light sleeper, since corridor traffic on the main berth area is constant.

Flights are uneventful, but Guwahati airport is small and gets congested during the 11 am bank of arrivals. And if you land in that window, expect 25 minutes for baggage. Coming back, get to Guwahati airport 90 minutes before domestic departure during festival season, since the security line snakes outside the terminal.

For verifying anything yourself, the most reliable open sources I use are the Wikipedia Shillong page for general facts, Wikivoyage Meghalaya for traveler-chosen tips, the official Meghalaya Tourism site for current advisories, and IRCTC for real-time train availability and tatkal timings.

FAQ

Q1. Is there any direct flight from Delhi to Shillong?
There are occasional ATR services to Shillong Airport at Umroi via Kolkata, but they cancel often and pricing runs INR 18,000 to 28,000. For practical purposes, treat Delhi to Shillong as Delhi to Guwahati plus a 110 km road transfer.

Q2. How long is the train from Delhi to Guwahati?
The fastest is the 12423 Dibrugarh Rajdhani at around 28 hours 30 minutes. The Brahmaputra Mail is 31 to 32 hours. Avadh Assam Express can stretch to 34 hours.

Q3. What is the cheapest legal way from Delhi to Shillong?
Brahmaputra Mail sleeper class at around INR 850 plus a shared sumo from Paltan Bazaar Guwahati at INR 350, total around INR 1,200 to 1,400 in 33 to 35 hours.

Q4. Do I need an Inner Line Permit for Meghalaya?
No. Indian and most foreign tourists don't need an ILP for Shillong, Cherrapunji, or anywhere in Meghalaya. Hotels handle foreign-national registration for you.

Q5. How much is a taxi from Guwahati airport to Shillong?
The Meghalaya Tourism Corporation prepaid counter inside arrivals quotes INR 1,800 to 2,500 for a sedan, INR 2,800 to 3,500 for a Innova or Xylo, fixed rate, no haggling. The drive is about 3.5 hours.

Q6. Are shared sumos safe for solo female travelers?
Yes, in my experience and from friends who travel alone. Daytime departures from Paltan Bazaar are full and well-trafficked. Avoid the last sumo of the day, which sometimes leaves after dark on the descent into Shillong.

Q7. What time should I land at Guwahati for the same-day Shillong transfer?
Land before 1 pm if possible. Shared sumos stop running by 5 pm and private taxi drivers add a surcharge after 5 pm. A 9.40 am IndiGo from Delhi gets you to Guwahati by 12.10 pm, comfortably in the window.

Q8. Can I book the Guwahati-Shillong taxi in advance from Delhi?
Yes. MTC and several private operators take WhatsApp bookings. Confirm 24 hours before, share your flight number, and ask for the driver's mobile. I usually pay 50 percent on arrival, 50 percent in Shillong, and have never had an issue.

There's no single right answer for the Delhi to Shillong question. Fly if your week is short, take the train if your week is long, mix the two if you want the best wallet outcome. The route is forgiving, the road from Guwahati is one of the prettier highway climbs in India once you get past Nongpoh, and Shillong is going to feel worth every hour you put into reaching it.
