How to Actually Reach the Andamans in 2026: The Best Mainland Gateways and Island Connections for Port Blair
By Aarav Sharma (Aarav Sharma covers island and remote-destination travel logistics across South and Southeast Asia.) · Published · 10 min read
Every flight to Port Blair routes through a handful of mainland gateways, and your choice of gateway quietly decides both your fare and your reliability. This guide breaks down which connecting city to pick, how to time the single daylight-only landing window, and how island-hopping onward to Havelock actually works.
There is no nonstop from most of India — and why that matters
Veer Savarkar International Airport at Port Blair (IXZ) is the only airport you can fly into in the Andaman & Nicobar Islands, and it sits roughly 1,200 km off the mainland coast. Unless you live in one of a few specific cities, you will not get a nonstop — your journey is a connecting itinerary through a mainland gateway, and choosing the right gateway is the single biggest decision you'll make.
The three gateways that matter are Chennai (MAA), Kolkata (CCU) and Bengaluru (BLR), with Chennai historically offering the most frequencies and the shortest hop across the Bay of Bengal. Delhi and Mumbai travellers almost always connect through one of these three.
Because IXZ has a daylight-operations constraint and limited slots, schedules are tight and the cheap fares fill early. Treat Port Blair as a destination you plan, not one you grab last-minute.
Chennai: the shortest and usually most reliable hop
Chennai is the closest major mainland gateway to Port Blair and typically the workhorse. The MAA–IXZ leg is short, frequencies are the highest of the three, and there's enough daily capacity that if one flight is disrupted you have realistic same-day or next-morning alternatives. For travellers from the south and west, connecting through Chennai usually means the least backtracking.
Reliability is the underrated reason to favour Chennai. Because IXZ can only handle daytime landings, a morning departure from a nearby gateway gives the schedule slack to absorb a small delay and still land within the daylight window. The shorter the over-water leg, the more forgiving the timing.
The trade-off is that popular Chennai morning flights price up fast in peak season (roughly October to early May, the dry window), so book the gateway-to-island leg as early as you can lock your dates.
Kolkata and Bengaluru: when they make sense
Kolkata is the natural gateway for travellers from eastern and northeastern India, and the CCU–IXZ leg is comparable in distance to Chennai's. If you're starting anywhere in the east, routing through Kolkata avoids a long, fare-padding detour down to Chennai. Frequencies are thinner than Chennai's, so build in a bigger buffer and have a backup flight in mind.
Bengaluru works best for travellers already in or near the city, or when a BLR–IXZ fare on your date simply comes out cheaper than the Chennai option — which does happen, because these are demand-priced leisure routes. The Bengaluru leg is a touch longer over water, so favour the earliest departure of the day to stay comfortably inside the daylight landing window.
The honest answer is that the cheapest reliable gateway varies by date and by where you start. Price all three for your exact travel days rather than assuming Chennai always wins.
The single-stop rule and the daylight landing window
For Port Blair, prefer a single-stop itinerary over anything with two connections. Each extra connection multiplies delay risk, and because the final landing must happen in daylight, a cascading delay can mean an overnight you didn't plan for at the gateway. One clean connection through Chennai, Kolkata or Bengaluru is the sweet spot.
If your home city forces two legs (for example a smaller town to a metro, then metro to IXZ), strongly consider doing it as a through-booking on a single PNR where possible, so a delay on the first leg obligates the airline to protect your onward seat. A self-connected two-ticket version through a gateway is riskier here than almost anywhere else in India, precisely because there's no evening recovery flight.
Whatever you book, target an arrival into IXZ before early afternoon. That leaves margin for the onward ferry or seaplane to Havelock and a comfortable check-in, rather than a frantic dash.
Island-hopping onward: Port Blair to Havelock and Neil
Most visitors don't stay in Port Blair — they push on to Havelock (Swaraj Dweep) and Neil (Shaheed Dweep), the islands with the famous beaches. The standard way is by ferry from Port Blair's jetty. Private air-conditioned catamaran operators run multiple daily sailings to Havelock (roughly 1.5–2 hours) with government ferries as a cheaper but less predictable option.
Book the onward ferry in advance during peak season — sailings sell out, and tickets for the popular catamaran operators are typically bought online ahead of time. Crucially, leave a cushion between your flight landing and your ferry departure: a tight same-day connection between a delayed flight and a fixed ferry is a common way trips go wrong. Aim for at least three hours, or simply spend your arrival night in Port Blair.
Inter-island sailings (Havelock–Neil and back) also run daily, so a Port Blair–Havelock–Neil–Port Blair loop is straightforward to sequence if you book each ferry leg ahead. Verify current timings and operators on the official ferry booking portals before locking your plan.
Season, weather and the monsoon caveat
The comfortable window for the Andamans runs roughly from October to mid-May. The southwest monsoon (broadly June to September) brings heavy rain and rough seas, which can suspend ferry sailings and seaplane operations even when flights are running. If you travel in the monsoon shoulder, treat island-hopping plans as provisional and keep them flexible.
Sea conditions, not just air weather, are the real constraint once you land. A flight can operate perfectly while the Havelock ferry is cancelled for swell. Build at least one buffer day into any itinerary that depends on a specific sailing, and never schedule your return flight for the same day you're due back from an outer island.
For the dry season, the bigger risk is simply availability — flights, ferries and the better hotels all fill well ahead. Lock the gateway-to-island flight first, then the ferries, then accommodation.
A booking order that holds up
Sequence the booking to protect the hardest-to-change pieces first. Start with the gateway-to-Port-Blair flight, because IXZ slots and cheap fares are the scarcest link. Pick your gateway by pricing Chennai, Kolkata and Bengaluru for your exact dates and weighting Chennai's reliability advantage.
Next, book the home-city-to-gateway leg, ideally as a single through-fare with the IXZ leg if one carrier offers it, so the connection is protected. Only then book the Havelock and Neil ferries, and finally your hotels, leaving a buffer night in Port Blair on arrival.
A metasearch view that compares all three gateways at once saves real money here, since the cheapest reliable routing genuinely shifts by date. Compare them side by side, confirm live fares and ferry timings on official sites, and you'll reach the islands without the usual scramble.
Frequently asked questions
Which city is the best to connect through for Port Blair flights?
Chennai is usually the best default — it's the closest mainland gateway, has the most frequencies, and the short over-water leg makes it the most reliable for hitting Port Blair's daylight-only landing window. Kolkata suits eastern India and Bengaluru can be cheaper on specific dates, so price all three for your exact travel days.
Is there a nonstop flight to Port Blair from Delhi or Mumbai?
Generally no — most travellers from Delhi and Mumbai connect through Chennai, Kolkata or Bengaluru. Port Blair (IXZ) is the only airport in the Andamans, it sits about 1,200 km offshore, and it operates daytime landings only, so plan a single-stop itinerary rather than expecting a nonstop.
How do I get from Port Blair to Havelock Island?
By ferry from Port Blair's jetty. Private air-conditioned catamaran operators run several daily sailings to Havelock (Swaraj Dweep) in roughly 1.5–2 hours, with cheaper government ferries as a backup. Book ahead in peak season and leave at least three hours between your flight landing and the ferry.
When is the best time to visit the Andamans?
Roughly October to mid-May, the dry season with calmer seas. Avoid the southwest monsoon (about June to September), when heavy rain and rough water can suspend ferry and seaplane services even when flights operate normally.
Should I book a single ticket or self-connect for Port Blair?
Prefer a single through-booked PNR for the connection. Because Port Blair lands only in daylight, there is no evening recovery flight, so a self-connected two-ticket itinerary that misses its onward leg can strand you overnight at the gateway. The protection of one PNR is worth more here than almost anywhere else.
Can rough weather cancel my island ferry even if my flight is fine?
Yes. Sea conditions are a separate constraint from air weather, and swell can cancel the Havelock or Neil ferry while flights run normally. Build at least one buffer day into ferry-dependent plans and never book your return flight for the same day you're due back from an outer island.
