The market-low column is the cheapest fare in our Travelpayouts cache on that corridor across all carriers, not a IndiGo-only price — use it as a floor when comparing.
A network across many countries means many rulebooks. IndiGo’s corridors in our catalogue touch 2 countries: India, Nepal. Each has its own regulator, so passenger rights attach not only to the airline but to the country the flight departs from. Two flights on the same airline can carry completely different entitlements.

IndiGo’s checked-baggage baseline is 15 kg.
Non-aligned does not mean no agreements. IndiGo sits outside the global alliances, but many unaligned carriers hold bilateral interline or codeshare agreements — enough for through-checked bags and re-routing. The reliable test is whether the whole journey can be issued as one ticket. If it can, an agreement exists behind it.
That 7/10 is our own score. Brand strength is an editorial assessment by our team for the Thai market, used to decide how deeply we cover a carrier. It is not a safety rating, not a punctuality rating and not a service score from any independent body. We say so here so you can weigh the number correctly.
IndiGo network & booking
IndiGo’s network in our catalogue covers 9 corridors, based at Bodh Gaya (GAY), Varanasi (VNS), Delhi (DEL), Mumbai (BOM), Kolkata (CCU) and Bhairahawa (Lumbini) (BWA). Cached fares across them run from ฿7,293 (BKK–DEL) to ฿13,368 (BKK–VNS). Those corridors carry about 120 weekly departures counting every carrier on the same city pairs.
In this catalogue IndiGo’s network reaches 7 destinations across 2 countries — India and Nepal. Most corridors serve Buddhist pilgrims and ASEAN & regional leisure travellers. All fares are shown in Thai baht (THB); compare live prices and schedules for each city pair on the route pages, and infant fares run about 15% of the adult fare. The lowest fare in our cache across this network is about ฿5,826 on BKK-VNS — prices move with season, so check live fares before booking.
The wide range reflects distance, not pricing policy. This network mixes short and long corridors, and fares track cost per seat-kilometre before anything else. Comparing prices across routes in one table tells you which corridor is cheaper, never which is better value. Use the individual route guides to compare within a single city pair — the only comparison that means something.
Passenger rights & compensation
IndiGo is registered in India and answers primarily to India DGCA (CAR Section 3). The common misreading is that rights travel with the airline. In practice they change first with the country the flight departs from. Those corridors reach 7 destinations in 2 countries.
IndiGo passenger protection is governed by India DGCA (CAR Section 3) — covering care, rerouting and refunds for cancellations/long delays. There is no fixed EU261-style cash schedule; check the regulator’s official terms before filing.
Baggage runs on a separate legal frame. Liability for baggage lost, damaged or delayed on an international journey sits under the Montreal Convention 1999 where both states are parties. Caps are denominated in SDR and revised periodically, so only the current figure is usable. Crucially this is independent of delay compensation: you can have no compensation claim and still have a baggage claim.
Collect evidence from day one. Whichever frame applies, the burden of proof sits with the passenger. Keep every boarding pass, the airline’s own delay notice or message, receipts for food and accommodation while you waited, and the actual arrival time against the scheduled one. Most rejected claims fail not because there was no right but because nothing documented what actually happened when.
How IndiGo fits travellers
IndiGo appears on 9 corridors in our catalogue. IndiGo’s corridors in our catalogue distribute across passenger clusters as: ASEAN & regional leisure (5), Buddhist pilgrims (4), with 3 flagged as labour/migrant corridors. The split is computed from our own route data, not from the airline’s marketing.
IndiGo’s catalogued routes matter most to the Buddhist pilgrims and ASEAN & regional leisure segment(s). Its Bodh Gaya (GAY), Varanasi (VNS), Delhi (DEL), Mumbai (BOM), Kolkata (CCU), Bhairahawa (Lumbini) (BWA) hub(s) are the main transit points. Compare schedules, baggage and fares against other carriers on the route pages before booking.
Why the cluster split matters to you. The dominant passenger group on a corridor sets several things the fare table cannot show. Labour and pilgrimage routes move groups with heavy baggage, which lengthens desk and gate times in particular hours; regional leisure routes travel lighter and process faster. Budget your airport time by the character of the corridor you are on, not by a general average.
Your rights do not change with the cluster you fall into. The segmentation on this page is an editorial tool for deciding what to explain where. It is not a fare class and it has no legal effect. Two passengers on the same flight who paid different prices for different reasons hold identical statutory rights. What actually changes them is the departure country, the carrier’s nationality and whether the flight is scheduled or chartered.

IndiGo in our fare record
Across 31 weekly fare captures on corridors IndiGo serves, the code 6E appears as the carrier holding the low 3 times — 10%. The cheapest such reading was ฿11,127 on BKK–GAY in week 2026-W31. The checked-baggage baseline we record is 15 kg.
Where this carrier holds the low most often. BKK–GAY (2×), BKK–VNS (1×). On those corridors IndiGo is the reference price to beat. Elsewhere in the network the low falls to other carriers more often, which is why checking two or three airlines before booking still pays even when you already intend to fly this one.
What this measures, and what it does not. We capture each corridor’s lowest fare once a week and record which carrier code that value was attached to. The 10% figure therefore says how often this airline surfaced as the cheapest option in the window we observed. It does not say whether the airline is expensive or cheap on average, and it says nothing about what the others charged that week. A low share is not evidence of a high price.
FAQ
How many routes does IndiGo fly in the SiamFlights catalogue?
IndiGo (6E) serves 9 routes relevant to travellers from Thailand in our catalogue.
What is IndiGo’s checked-baggage allowance?
A 15 kg baseline. Always confirm on the official site before travel.
What alliance is IndiGo in?
IndiGo is non-aligned.
Which regulator oversees IndiGo?
India DGCA (CAR Section 3), by country of registration. But passenger rights are set first by the country the flight departs from — anything leaving Thailand sits with Thailand CAAT.
Does the IndiGo infant fare include a seat?
No. The roughly 15% rate applies to a lap infant with no seat of its own. A separate seat makes it a child fare, priced as a share of the full fare.
Is the low-fare column IndiGo’s own price?
No. It is the cheapest fare our cache recorded on that corridor across every carrier serving it. On a multi-carrier route the low may belong to a competitor.
