Flights Bangkok to Guangzhou (BKK-CAN): Airlines, THB Fares

Bangkok to Guangzhou is one of the busiest short-haul links between Thailand and southern China, with around 35 flights a week. The cabin is a working mix — traders and business travellers heading for Guangzhou’s wholesale markets and the twice-yearly Canton Fair, alongside tourists and families visiting relatives in both directions. At roughly three hours’ block time it is an easy daytime hop, and the high frequency means missing one flight rarely costs more than a few hours.

Corridor profile

The BKK–CAN corridor runs about 35 departures a week across 4 carriers, with an average block time of 3.0 hours, and the lowest fare the feed returned for this route is ฿5,006. The frequency figure counts every carrier on the route combined, not any single airline.

Our own demand score. This corridor scores 7/10. 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.

What frequency tells you when plans break. 35 weekly departures is ~5 departures a day — if one departure is cancelled there is normally another the same day. That is why frequency matters more than price for anyone with a fixed commitment at the other end. A thin corridor deserves a buffer day before anything that cannot move, not because the airline is poor but because there is no spare inventory to shift you onto.

Airlines & baggage

Baseline baggage on BKK–CAN runs 7–30 kg across the 2 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 BKK–CAN — 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 10 monthly lows spanning a 25% range.

Four carriers share BKK-CAN: Thai Airways and China Southern run full-service widebodies, while Spring Airlines (9C) and Thai AirAsia fly the route as low-cost. That split gives travellers a real choice — a fuller fare with checked baggage and a meal included, or a bare fare to which bags are added later. China Southern’s Guangzhou base means the widest schedule and the easiest onward connections deeper into mainland China.

Compare totals, not headline numbers. Thai AirAsia price the seat low and sell bag, seat and meal separately; Thai Airways fold them into the fare. Comparing the first number you see compares two different products. Add one bag and one seat assignment on both sides, then read the final figure. On medium-haul and longer, the remaining gap is frequently smaller than the search page suggests.

Fare trends

Between 2026-W20 and 2026-W31 we captured the BKK–CAN low 3 times, ranging ฿2,727 to ฿5,229 — a 92% spread. The cheapest reading fell in week 2026-W29, and from first capture to last the low moved down 4%.

With 35 weekly flights and both full-service and budget carriers competing, BKK-CAN is one of the better-priced China routes from Bangkok. The Canton Fair periods in spring and autumn push fares up and fill seats early, so those dates are worth booking two to three months ahead. Outside the fair, four to six weeks of lead time usually secures a reasonable economy fare in THB, and the low-cost carriers run frequent promotions.

Why week 2026-W29 read cheapest. We do not assign a cause: our data records prices, not reasons. Weekly lows move with whatever promotional inventory remains, capacity adjustments, and the travel dates the system happened to surface that pass. What this series is actually good for is a proven floor, not a rule about which day to book.

Seasonality & best time to book

Our catalogue lists 4 carriers on this city pair. BKK–CAN 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.

Bangkok–Guangzhou 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 35 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 Guangzhou

Guangzhou (CAN) sits in China. The flight from Bangkok runs about 3.0 hours. The lowest fare the feed returned for this route is ฿5,006 on a 2026-10-01 departure. The trend figures rest on 3 weekly captures since week 2026-W20.

Guangzhou is the commercial heart of southern China — a Pearl River port city built on trade and the long-running host of the Canton Fair, the country’s largest import-export exhibition. Beyond business it has a dense old core around Shamian Island and the Cantonese cooking the city is known for. For most Thai travellers it is either a buying trip or a gateway for onward travel across China, well connected by high-speed rail.

Local time at the destination. Guangzhou runs on Asia/Shanghai, 1h ahead of Bangkok. The gap holds all year; the zone does not shift its clocks. The offset matters most on overnight flights, because the times on a ticket are local at each end rather than an elapsed duration. Misreading the arrival time is a common way to book a transfer or a hotel night on the wrong date.

Passenger rights on BKK–CAN

Our catalogue lists 4 carriers on this city pair. Departures from Thailand fall under Thailand CAAT; the return from Guangzhou falls under Civil Aviation Administration of China (CAAC). 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 Civil Aviation Administration of China (CAAC), 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 loss and delay run on a separate rulebook. An airline’s liability for baggage that is lost, damaged or delayed on an international journey sits under the Montreal Convention 1999 where both the origin and destination states are parties. The caps are denominated in SDR and revised periodically, so only the current figure is usable. This frame is entirely separate from delay compensation: you can have no compensation claim and still have a baggage claim.

Block time is ~3.0h, with ~35 flights per week across all carriers.

When is BKK-CAN 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 BKK–CAN, 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 BKK–CAN flight is cancelled, who is responsible?

The destination sits with Civil Aviation Administration of China (CAAC), 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.
