Flights Phuket to Mumbai (HKT-BOM): Airlines, THB Fares

Phuket to Mumbai connects the Andaman coast with India’s financial capital, with around seven flights a week. The route carries Indian holidaymakers and wedding parties heading for Phuket’s beaches and resorts, balanced by Thai travellers bound for Mumbai. Block time is about four and a half hours, a comfortable single sector.

Corridor profile

The HKT–BOM corridor runs about 7 departures a week across 2 carriers, with an average block time of 4.5 hours, and the lowest fare the feed returned for this route is ฿9,886. The frequency figure counts every carrier on the route combined, not any single airline.

Combined frequency is not your airline’s frequency. Those 7 weekly departures are spread across 2 carriers, and when your flight is cancelled only the airline holding your ticket owes you a seat. A rival’s empty seat on the same city pair does not help unless an interline agreement exists or you are willing to buy a second ticket. That is why a multi-carrier route is not automatically the safer one it appears to be.

“Direct” and “nonstop” are not synonyms. The 4.5-hour figure is an average gate-to-gate block time for a nonstop, taxi time included but connections, check-in and immigration excluded. In booking systems “direct” means only that the flight number does not change — a single-number flight can still put down en route to refuel or pick up passengers. The word that guarantees no intermediate landing is nonstop. Filter on that one if the clock matters.

Airlines & baggage

Baseline baggage on HKT–BOM runs 15–25 kg across the 2 of 2 carriers on the route for which we hold a row. These are carrier reference baselines, not entitlements attached to every ticket: cabin class, fare brand and frequent-flyer status all change the weight you actually get.

The low number in the table is not a checked allowance. The 15 kg baseline we record for IndiGo belongs to an unbundled fare structure, which by design reflects the cabin entitlement. Hold baggage is sold per sector and priced by the weight tier you pick and how early you buy it. The practical effect is that the cheaper headline fare closes most of its gap the moment you add one bag. Compare totals after bag, seat and meal are selected — that is the only comparison that holds against a full-service carrier.

Two pricing models on one corridor. Air India record a baseline up to 25 kg with baggage, meal and seat selection already inside the fare; IndiGo price each of those separately. The difference the table cannot show is what happens when the flight goes wrong: a full-service carrier has the network and the agreements to move you onto something else, while an unbundled ticket is usually limited to the next departure of the same airline.

Airlines on this route

2 carriers operate HKT–BOM — 1 full-service and 1 low-cost. Alliances present on the route: Star Alliance. Multiple carriers only affect price when both sides are actually selling in the same window. We hold 5 monthly lows spanning a 49% range.

Two carriers fly HKT-BOM: IndiGo and Air India. IndiGo operates the route as a low-cost service with a slim base fare, while Air India runs a full-service cabin with checked baggage and meals included. Both fly direct, so the practical choice is between the lower headline fare and the fuller all-in product.

The floor changes hands. Across our 2 weekly captures (2026-W20–2026-W31) the lowest fare sat with 2 different carriers, Thai Vietjet holding it most often at 1 of them. Loyalty to one airline on this corridor therefore has a price. With N=2 this is a small sample — directional, not conclusive.

What an alliance buys, and what it does not. Star Alliance on this route means through-checked bags, conditional lounge access, and — the part that matters — a realistic chance of being moved onto a partner’s aircraft when things break. What an alliance does not buy is compensation. That comes only from the law of the jurisdiction involved, never from a logo on the ticket.

Fare trends

We hold only 2 weekly captures for this corridor — too few to call a trend. Read what follows as an explanation of the mechanics rather than a forecast. We capture the lowest observed fare once a week and accumulate the series over time.

With two carriers competing, HKT-BOM is reasonably priced for an international route. Demand lifts around the Indian wedding season and the Diwali holidays, when Phuket is a popular destination for celebrations — those weeks are worth booking two to three months ahead. For ordinary dates, four to six weeks of lead time usually secures a reasonable economy fare in THB.

Sparse data usually means a sparse market. Our capture cadence is identical on every corridor, so the number of readings reflects how often this route offers a fare to catch at all. Seasonal routes, charter-heavy routes and routes sold through narrow channels return values irregularly. Where that is the case, asking the airline or an agent directly gets you a truer picture faster than watching a search page.

Seasonality & best time to book

Our catalogue lists 2 carriers on this city pair. HKT–BOM is a regional corridor with a shorter booking window than long-haul. The fare tracks low-cost promotional cycles and Thai long weekends more than any season at the destination, and Songkran plus the consecutive-holiday blocks are the tightest weeks of the year.

Phuket–Mumbai fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.

The booking window matters more than the booking day. On a 4.5-hour corridor the fare tracks how many seats remain in each fare bucket, not which weekday you click buy. The folklore about a magic booking day has no support in the series we capture. What does show up is widening your travel dates by a day or two.

Thai public holidays are the controllable variable. The holiday calendar is published a year ahead and is the one part of the equation you know before the airline reprices. Shifting out of a consecutive-holiday week by even two days moves you off the tightest demand for both seats and rooms — a bigger effect than switching airline.

About Mumbai

Mumbai (BOM) sits in India. The flight from Phuket runs about 4.5 hours. We hold 5 monthly lows spanning a 49% range. This corridor scores 6/10 on our own catalogue demand ranking. Our catalogue lists 2 carriers on this city pair.

Mumbai is India’s financial and entertainment capital — a coastal megacity on the Arabian Sea, home to the country’s stock exchange and film industry, with colonial-era landmarks like the Gateway of India and a celebrated street-food culture. For Thai travellers it is a business destination and a busy gateway into western India.

What visa-free does not mean. Entering without a visa in advance is not a right to work, not a right to study, and not a guarantee of admission — the officer at the border still decides. The conditions most often forgotten are remaining passport validity, an onward ticket and proof of accommodation. All three are asked for more often than travellers expect, and their absence lets the airline refuse boarding at the departure airport.

Passenger rights on HKT–BOM

Our catalogue lists 2 carriers on this city pair. Departures from Thailand fall under Thailand CAAT; the return from Mumbai falls under India DGCA (CAR Section 3). The two regimes are not the same, and what you are owed changes with the direction of travel and the nationality of the operating carrier — never with the fare you paid.

No European-style compensation schedule applies here. The destination sits with India DGCA (CAR Section 3), which typically imposes duty of care, re-routing and refund obligations but no fixed EU261-style cash bands. The enforceable floor is therefore the airline’s own conditions of carriage plus Thailand CAAT rules for departures from Thailand. Read the conditions of carriage before you buy — that is the document that actually binds you.

Baggage and delay are governed by different instruments. If a bag is lost or arrives late on an international journey, the basis of claim is the Montreal Convention 1999, which applies where both the origin and destination states are parties. Its ceilings are denominated in SDR and revised periodically, so only the current figure is citable. The practical consequence is that the two claims are independent: having no delay-compensation right does not remove a baggage claim, and the report should be filed at the baggage desk before you leave the airport.

FAQ

How long and how often is the HKT-BOM flight?

Block time is ~4.5h, with ~7 flights per week across all carriers.

When is HKT-BOM cheapest to book?

Book 4–8 weeks ahead; avoid Songkran, school holidays and peak season to save 15–30%.

What exactly is the lowest fare shown on this page?

It is the cheapest fare our cache has recorded on HKT–BOM, captured one snapshot at a time. It is not an average, not a live quote and not a guarantee that a seat still exists at that price. Use it as a reference floor, then check live pricing.

What is the difference between a direct and a nonstop flight?

Direct means the flight number does not change, but the aircraft may still land en route. Nonstop means no intermediate landing at all. If the clock matters, filter on nonstop, not direct.

If my HKT–BOM flight is cancelled, who is responsible?

The destination sits with India DGCA (CAR Section 3), which generally imposes duty of care, re-routing and refunds but no fixed EU261-style cash bands. The enforceable floor is the airline’s conditions of carriage plus Thailand CAAT rules for departures from Thailand.

Will my bag be through-checked if I book two separate tickets?

No. Through-checking happens only when every sector is on one ticket or an interline agreement exists. On separate tickets you reclaim the bag, clear the transit country’s immigration and check in again — and a missed connection is a new ticket at your cost.
