Flights Phuket to Singapore (HKT-SIN): Airlines, THB Fares

Phuket to Singapore links Thailand’s largest resort island directly with the city-state, a busy route — around 42 flights a week — running heavily on leisure traffic. It carries Singaporean visitors heading to Phuket’s beaches and travellers from Phuket reaching Singapore for shopping, business or onward connections.

Block time is about 1.9 hours. With a mix of full-service and low-cost carriers and this much frequency, the route is competitive and easy, and demand tracks both Phuket’s tourism season and Singapore’s holiday periods.

Corridor profile

The HKT–SIN corridor runs about 42 departures a week across 4 carriers, with an average block time of 1.9 hours, and the lowest fare the feed returned for this route is ฿4,350. The frequency figure counts every carrier on the route combined, not any single airline.

“Direct” and “nonstop” are not synonyms. The 1.9-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.

Our own demand score. This corridor scores 8/10. That is an editorial ranking we use to prioritise how deeply we cover a route — it is not a passenger count and not a price index. A high score means a corridor people search and where options exist, which usually means price competition. A low score does not mean a bad route; it means fewer options, and where options are few, flexibility gets expensive.

Airlines & baggage

Baseline baggage on HKT–SIN runs 7–30 kg across the 3 of 4 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.

Bags through-check only on one ticket. The carriers we hold rows for on this corridor are not all in the same alliance. A bag runs through to your final destination only when every sector sits on one ticket, or an interline agreement exists between the operators. Self-connect on two separate tickets to shave the total and you collect the bag, clear the transit country’s immigration, and check in again — and the time you must allow is far longer than a booking screen implies.

Airlines on this route

4 carriers operate HKT–SIN — 1 full-service and 2 low-cost. Alliances present on the route: Star Alliance. Multiple carriers only affect price when both sides are actually selling in the same window. The lowest fare the feed returned for this route is ฿4,350 on a 2026-08-22 departure.

Four carriers fly HKT-SIN: Singapore Airlines on the full-service side, with Scoot, Thai AirAsia and Jetstar Asia covering the low-cost end. Singapore Airlines includes baggage and a fuller cabin; the low-cost carriers price the seat low and sell extras separately. For a beach trip with luggage, add checked baggage to the low-cost headline fare before comparing it with the full-service option.

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

Between 2026-W20 and 2026-W31 we captured the HKT–SIN low 5 times, ranging ฿2,049 to ฿4,525 — a 121% spread. The cheapest reading fell in week 2026-W27, and from first capture to last the low moved down 4%.

HKT-SIN fares are competitive given the frequency, lifting around Phuket’s cool-season high season, Singapore’s holiday periods and the year-end. For those windows, six to ten weeks of lead time is sensible. Outside them, the low-cost carriers’ early fares are the cheapest seats, and three to six weeks usually finds a good THB price. The monsoon months are the quietest and cheapest.

Who holds the floor. Across 5 captures Scoot held the low 2 times and no other carrier took it once in this window, which makes that airline’s price the corridor’s reference number. With N=5 and a weekly cadence, short promotions can slip between captures.

How to read a 121% spread. The gap between the cheapest and dearest week is the size of the movement this corridor showed in the window we observed. A wide spread means timing matters a lot; a narrow one means the fare is stable and watching it is not worth your time. The figure measures only the lows we captured, not every seat sold that week.

Seasonality & best time to book

Our catalogue lists 4 carriers on this city pair. HKT–SIN 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–Singapore fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.

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.

Frequency is seasonal too, not just price. The 42 weekly departures in our catalogue is an estimate of the standard schedule; carriers add and cut rotations by season. That means the cheapest month can also be the month with the fewest options — and with fewer rotations, one cancellation hurts more. Read price and frequency together.

About Singapore

Our catalogue lists 4 carriers on this city pair. Singapore (SIN) sits in Singapore, uses SGD, and the visa position we record for a Thai passport is: visa-free 30 days (ASEAN). The flight from Phuket runs about 1.9 hours. Singapore — business + leisure hub, visa-free 30 days

Singapore, the destination of this route, is a compact and efficient city-state at the foot of the Malay Peninsula. On this corridor it works two ways at once — a short, polished city break for travellers from Phuket, and the home end of an island holiday for Singaporean visitors. Reached via Changi Airport, Singapore also serves as a connecting point, which adds onward-bound passengers to what is otherwise a leisure-led route.

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–SIN

Our catalogue lists 4 carriers on this city pair. Departures from Thailand fall under Thailand CAAT; the return from Singapore falls under Singapore CAAS. 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 Singapore CAAS, 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.

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–SIN, 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–SIN flight is cancelled, who is responsible?

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.
