Which Airports Unlock the Northeast in 2026? Chaining Guwahati, Imphal, Agartala and the Newer Terminals on One Multi-City Trip

The Northeast is eight states stitched together by a small set of airports, and treating it as one stop is how travellers waste days backtracking. This guide explains which airport to base from, how to chain destinations on a single multi-city ticket, and which states still need an Inner Line Permit.
Guwahati is the gateway: why almost every itinerary starts here
Lokpriya Gopinath Bordoloi International Airport in Guwahati is the connectivity anchor for the entire region. As of 2026 it carries by far the most daily frequencies and the widest set of direct links to Delhi, Kolkata, Mumbai, Bengaluru and other metros, and it is the most reliable place to find a same-day onward flight deeper into the Northeast. If you are flying in from the rest of India, routing through Guwahati almost always gives you the most options and the lowest fares.
The practical implication is that Guwahati works best as a hub rather than a destination in itself. Many travellers fly into Guwahati, spend a night, then fan out to Shillong (a short road transfer rather than a flight for most), Tawang's nearest air access, or onward sectors to Imphal, Agartala, Dibrugarh and Aizawl. Build your itinerary outward from Guwahati and you will spend far less time backtracking.
The other airports and what each one actually unlocks
Each Northeast state has at least one operating airport, but their roles differ sharply. Imphal (Manipur) and Agartala (Tripura) are the two busiest after Guwahati and have the most direct-metro options, which makes them viable secondary entry points rather than only onward stops. Dibrugarh and Jorhat open up Upper Assam and the tea-and-wildlife belt around Kaziranga. Dimapur is the air gateway for Nagaland, and Lengpui serves Aizawl in Mizoram.
- Guwahati (GAU) - primary hub, most frequencies.
- Imphal (IMF) and Agartala (IXA) - strong secondary entry points.
- Dibrugarh (DIB) / Jorhat (JRH) - Upper Assam, Kaziranga access.
- Dimapur (DMU) - Nagaland gateway.
- Lengpui / Aizawl (AJL) - Mizoram.
- Tezu, Pasighat and newer Arunachal strips - limited, weather-sensitive frequencies that expand connectivity but should be treated as bonus rather than backbone.
Frequencies on the smaller fields change seasonally, so confirm current schedules before you commit a tight itinerary to them.
How to chain destinations on a single multi-city ticket
The mistake most first-time visitors make is booking a simple return to Guwahati and then improvising onward legs at local prices. A smarter approach is a multi-city (open-jaw) itinerary: for example, fly into Guwahati, out of Imphal or Agartala, and you avoid doubling back to where you started. Metasearch and airline multi-city tools let you price these as one journey, which often beats two separate round-trips on both fare and routing.
Sequence your legs geographically rather than by impulse, and leave realistic buffers, because a single weather-delayed Northeast sector can collapse a same-day connection. When you build the itinerary, compare the open-jaw price against two one-ways on a metasearch tool like the blog's linked search, since one structure is frequently cheaper than the other depending on carrier and dates.
Inner Line Permit: which states need it and which do not
This is the rule that trips up unprepared travellers. As of 2026, the Inner Line Permit (ILP) is required for Indian citizens visiting Arunachal Pradesh, Nagaland, Mizoram and Manipur. You do not need an ILP for Assam, Meghalaya or Tripura, which is part of why Guwahati-based, Shillong-and-Kaziranga style trips are so popular for a first visit.
ILPs for the states that require them can typically be obtained online in advance or, in some cases, on arrival, but the process, validity and entry points differ by state and do change. Foreign nationals face separate rules, including Protected Area Permit requirements in places. Always check the specific state government's official ILP portal close to your travel date, and carry both digital and printed copies, since you may be asked for it at the airport or at checkpoints.
Choosing your hub base: a decision framework
Pick your base by where the bulk of your nights will be, not by where the cheapest inbound fare lands. If your trip centres on Meghalaya, Kaziranga and Upper Assam, base from Guwahati and treat onward flights as optional. If Manipur or Tripura is the heart of the trip, flying directly into Imphal or Agartala can save a full day versus routing through Guwahati both ways.
For multi-state trips, the open-jaw structure usually wins: enter at the hub with the best inbound fare and exit from whichever airport sits closest to your final destination. Sketch the states you want, mark which need an ILP, then let geography and frequency, not habit, decide the entry and exit airports.
Timing, weather and buffer days you should plan for
Northeast aviation is weather-exposed. The monsoon months bring heavy rain and reduced visibility that can delay or cancel sectors into smaller fields, and winter fog affects early-morning departures. The drier window from roughly late autumn to early spring is the most reliable for tight multi-airport itineraries, though it is also the busiest, so book frequencies early.
Whatever the season, build at least one buffer day before any non-refundable onward commitment such as an international connection or a fixed permit-dated entry. A single missed sector in the Northeast is far harder to re-accommodate than a missed flight on a trunk route, simply because there are fewer daily alternatives. Verify live schedules and any weather advisories close to departure.
Frequently asked questions
Which airport is the best base for a Northeast India trip in 2026?
Guwahati (GAU) is the strongest hub because it has the most daily frequencies and the widest direct links to metros, making same-day onward connections easiest. Base from Imphal or Agartala only if Manipur or Tripura is the centre of your trip.
Can I visit multiple Northeast states on one flight ticket?
Yes. Use a multi-city or open-jaw itinerary, for example flying into Guwahati and out of Imphal or Agartala, so you avoid backtracking. Price it as one journey on a metasearch or airline multi-city tool and compare against two separate round-trips.
Which Northeast states need an Inner Line Permit in 2026?
As of 2026, Arunachal Pradesh, Nagaland, Mizoram and Manipur require an Inner Line Permit for Indian citizens. Assam, Meghalaya and Tripura do not. Always confirm on the relevant state government's official ILP portal before travelling.
Do I need to apply for the ILP before flying?
It depends on the state. Some allow online application in advance and some offer it on arrival, but the process, validity and accepted entry points vary by state and change. Apply ahead where possible and carry both digital and printed copies.
What is the best season to chain several Northeast airports?
The drier window from roughly late autumn to early spring is the most reliable for tight multi-airport itineraries, with the monsoon and winter fog posing higher delay and cancellation risk on smaller sectors. Book early as the dry season is busy.
How much buffer time should I leave between Northeast flight legs?
Leave generous buffers and at least one full buffer day before any non-refundable commitment such as an international connection or a fixed permit-dated entry, because weather-delayed sectors are hard to re-accommodate given the limited daily frequencies.
