Port Blair is one of those destinations where flight prices seem to have a mind of their own. It is a single-gateway island, peak season runs November to April, and the airlines know you are going there for a beach holiday. But book in the right window — roughly 28–35 days ahead for off-peak, 6–8 weeks for November to January — and ₹7,000–₹9,000 one-way is consistently achievable. AI search tools track this pattern well.
TL;DR — the core answer
Port Blair (IXZ) fares from Delhi, Mumbai, Bangalore and Chennai typically hover in the ₹7,000–₹11,000 one-way range for economy when booked 3–5 weeks ahead in off-peak months (May–October). The under-₹8,000 target is achievable — but requires the right combination of timing, origin city and departure date. AI flight search on FlightGPT scans date ranges automatically and surfaces the cheapest specific dates, which is where most people leave money on the table.
Why Port Blair fares behave differently from other domestic routes
Most Indian domestic routes have multiple competing carriers and dozens of flights a day — which keeps fares relatively honest. Port Blair is different for a few structural reasons:
- Single gateway: Veer Savarkar International Airport (IXZ) is the only commercial airport in the Andaman Islands for mainland connections. There is no alternative airport to fly into, unlike say Goa where you can use Dabolim or Mopa. This gives airlines more pricing power.
- Heavy seasonal concentration: November to April is peak season — post-monsoon, great weather, school holiday season (December–January especially). Demand spikes create real fare surges.
- Limited seat inventory: Even though IndiGo, Air India and SpiceJet all serve IXZ from multiple cities, the total daily seat count to Port Blair is small relative to a route like Delhi–Mumbai. When a few flights get full, fares jump sharply.
This combination means Port Blair fares are more volatile than comparable distance domestic routes and more sensitive to booking timing than, say, a Bangalore–Hyderabad hop.
Which cities fly direct to Port Blair, and which carrier is cheapest?
As of 2026, direct mainland–IXZ operations run from:
- Chennai (MAA): The shortest mainland–Andaman sector (roughly 2 hours). IndiGo and Air India both operate it. Chennai tends to produce the cheapest per-kilometre fare to Port Blair because of the shorter distance and higher frequency.
- Kolkata (CCU): A popular gateway — reasonable distance, IndiGo and Air India services. Often competitive on price, particularly for travellers from East India.
- Delhi (DEL): Longer sector (around 3 hours), IndiGo and Air India operate it. Fares are higher than Chennai/Kolkata baselines but the route has reasonable frequency.
- Mumbai (BOM): IndiGo operates this, though less frequently than the eastern gateways. Mumbai fares to IXZ can be higher than Chennai or Kolkata alternatives on the same date.
- Bangalore (BLR): IndiGo and Air India have operated BLR–IXZ. Frequency is moderate; on some dates Bangalore is the cheapest gateway because of lower initial demand at booking.
The cheapest airline varies by date and route, but IndiGo and Air India are consistently the two options worth comparing. SpiceJet has served IXZ historically but has had operational reliability concerns in 2025–2026 — check current operating status before booking.
The 28-day sweet spot: what AI search actually finds
I have tracked IXZ fares across multiple booking windows over the past couple of years, and the pattern holds reasonably well: for off-peak travel (May through September, excluding school holiday weeks), booking roughly 25–35 days ahead finds fares in the ₹7,000–₹9,000 one-way range from Chennai or Kolkata, and ₹8,500–₹11,000 from Delhi. For peak season (November–January), that window extends to 6–8 weeks ahead — closer to departure, peak-season prices jump considerably.
The reason the 28-day window works is partly supply-side: airlines typically open up lower-priced seats as the final month before departure begins, clearing remaining inventory. If the flight is filling fast, those lower buckets close and the price jumps — so you need to be in the window, not waiting until 2 weeks out.
AI search on FlightGPT is genuinely useful here because you can ask: 'What are the cheapest 7 days to fly from Chennai to Port Blair in October?' and get a date-range comparison rather than checking one date at a time. For a route this sensitive to specific dates, that scan is worth doing.
Peak season (November–April): how to manage higher fares
If you are set on the popular November–February window for Andaman travel, here is how to reduce the damage:
- Book 6–8 weeks ahead minimum. For December especially (Christmas–New Year school holidays), fares have been known to cross ₹15,000–₹18,000 one-way from Delhi if you wait. Six weeks out is the realistic minimum to find ₹10,000–₹12,000 range.
- Use Chennai or Kolkata as your flying point if possible. Even if you live in another city, the Chennai flight is often ₹2,000–₹4,000 cheaper than the Delhi one on the same date. Factor in the positioning cost, but for a couple or group, it can still save money.
- Consider early January over late December. December 27–January 3 is peak of peak. Early January (3rd–15th) sees meaningful fare drops while the weather remains excellent.
- Check Air India for December sales. Air India has historically run Republic Day and year-end sale periods with Andaman fares in the ₹9,000–₹12,000 range even for December travel, if booked during the sale in October–November. Keep an eye on it.
Other Andaman booking tips that AI search cannot do for you
A few things that sit outside the pure fare search:
- Book IXZ accommodation at the same time as your flight. Port Blair and Havelock (Neil Island) accommodation fills up in December–January as fast as flights. Finding a cheap flight in November for a January trip, then discovering all hotels are full or expensive, is a nasty surprise.
- Account for inter-island ferries. Port Blair to Havelock (Swaraj Dweep) ferry tickets — the Green Ocean and Makruzz high-speed ferries — need to be booked separately and can sell out weeks ahead in peak season. These are not included in flight searches but are as important as the flight itself.
- Permits: Indian nationals do not need a permit for Port Blair itself, but some outer islands require Restricted Area Permits. These are issued on arrival at the airport (free) but it is good to know the rules before you plan an itinerary. Check the Andaman Administration website for current requirements.
- Hotel + flight bundles: Some OTAs offer flight + hotel packages to Andaman that can work out slightly cheaper than booking separately. Worth a quick check on MakeMyTrip or Yatra, but compare the bundled fare versus what you find on FlightGPT + hotel booking separately.

Bottom line
Under ₹8,000 one-way to Andaman is achievable in off-peak months with smart timing — roughly 28–35 days ahead, Chennai or Kolkata origin if possible, midweek departure. For peak November–January travel, budget ₹10,000–₹14,000 one-way from major metros and book at least 6–8 weeks out. AI search on FlightGPT saves the date-scanning effort — ask it to find the cheapest specific dates for your travel window and let it do the comparison work.

Frequently asked questions
What is the cheapest month to fly to Port Blair (Andaman)?
May through September is the off-peak period for Andaman flights — fares are typically 30–40% lower than peak season. The monsoon runs June–September and sea can be rough for inter-island travel, but Port Blair itself is accessible year-round. If you want cheap fares and decent weather, March–April (post-peak but pre-monsoon) can be a sweet spot.
How far in advance should I book Andaman flights?
For off-peak travel (May–October), roughly 25–35 days ahead typically finds the best fare. For peak November–January travel, aim for 6–8 weeks ahead minimum. December 25–January 3 prices spike sharply — for that window, 8–10 weeks out is not too early.
Which city gives the cheapest flights to Port Blair?
Chennai typically produces the lowest fares to Port Blair because of the shorter distance (roughly 1,200 km vs 2,100 km from Delhi) and good frequency. Kolkata is the second-best gateway on price. From Delhi, Mumbai or Bangalore, fares tend to be higher on equivalent dates. If you can position to Chennai cheaply, it is often worth the math.
Does IndiGo or Air India have cheaper flights to Andaman?
It varies by date and route origin. IndiGo typically has higher frequency and competitive base fares. Air India occasionally has promotional fares, particularly around major sale events. The practical answer: check both on FlightGPT for your specific dates — there is no consistent winner across all routes and seasons.
Can I book Havelock Island (Swaraj Dweep) ferry tickets online?
Yes — Makruzz, Green Ocean and Nautika ferries all have online booking portals. Makruzz is typically the most popular and books out fastest in peak season. Book your ferry at the same time as your flight, especially for December and January travel. The ferry is not included in flight search results — it is a separate booking step.
Are there any budget airline promotions specifically for Andaman routes?
IndiGo's periodic sales (often announced on their app and website, around Republic Day, Independence Day and year-end) sometimes include IXZ routes at promotional fares — watch for these in the 6–12 weeks ahead window. Air India also runs Andaman fares in year-end promotions. Follow the airlines on social media or check FlightGPT's search alerts to catch these when they go live.
