Flights Bangkok to Beijing (BKK-PEK): Airlines, THB Fares

Bangkok to Beijing connects Thailand with the capital of China, a route carrying tourists in both directions, business travellers tied to the two economies, students, and the Chinese visitors who make up a major part of Thailand’s inbound tourism. Around 28 flights a week keep it a frequent, well-served link.

Block time is about 5 hours. With a broad line-up of Chinese and Thai carriers, full-service and low-cost, the route is competitive — and demand swings strongly with the Chinese holiday calendar, above all Lunar New Year and the autumn Golden Week.

Corridor profile

The BKK–PEK corridor runs about 28 departures a week across 5 carriers, with an average block time of 5.0 hours, and the lowest fare the feed returned for this route is ฿4,609. 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. 28 weekly departures is ~4 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–PEK runs 30 kg across the 1 of 5 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 labour-route uplift is conditional. Our data records a +10 kg uplift for Thai Airways on labour corridors. That uplift is a route-and-fare-class policy, not an entitlement stapled to every ticket: promotional and deep-discount fare brands frequently sit outside it, and the uplift applies to hold baggage only — it does not extend to the cabin allowance. Confirm it at ticketing and get it written on the ticket rather than trusting a promotional page.

Dedicated Hajj/Umrah charters are not in this table. The generous allowances pilgrims hear about are package terms an operator has contracted with an airline, not published entitlements on ordinary tickets, and the figures change season to season. Travelling with a group, work from the paperwork of an operator licensed through the Chularatchamontri Office. Buying a scheduled ticket yourself, you get that ticket’s allowance — not the package’s.

Airlines on this route

5 carriers operate BKK–PEK — all full-service. Alliances present on the route: Star Alliance. Multiple carriers only affect price when both sides are actually selling in the same window. We hold 12 monthly lows spanning a 67% range. This corridor scores 7/10 on our own catalogue demand ranking.

Five carriers fly BKK-PEK: Thai Airways and the major Chinese full-service airlines Air China, Hainan Airlines and China Southern, with Spring Airlines on the low-cost end. The full-service carriers include checked baggage; Spring Airlines prices the base seat low and charges extras separately. Comparing the all-in cost once baggage is added is the practical way to weigh the options on this route.

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 BKK–PEK low 5 times, ranging ฿4,609 to ฿5,478 — a 19% spread. The cheapest reading fell in week 2026-W31, and from first capture to last the low moved down 7%.

BKK-PEK fares swing hard with the Chinese travel calendar — Lunar New Year, the autumn Golden Week and the summer holidays are the busiest and dearest. For those peaks, eight to twelve weeks of lead time is sensible. Outside them, fares ease and a four-to-eight-week window usually finds a workable economy fare in THB, with Spring Airlines’ early fares the cheapest seats.

This is the lowest fare our feed returned for BKK–PEK, not a quoted price. It is the minimum of the record we hold for this one corridor — not the lowest value in our fare cache, not an average, not a live quote, and not a promise that a seat still exists at that number. An unusually low reading almost always traces to one carrier’s limited promotional inventory, which is gone before you reach checkout. Treat it as a reference line for how low this corridor can go, then check live pricing before deciding.

Seasonality & best time to book

Our catalogue lists 5 carriers on this city pair. BKK–PEK 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–Beijing fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.

Frequency is seasonal too, not just price. The 28 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.

What our data actually shows. Of the 12 months we captured, the cheapest reading was Sep 2026 at ฿4,609 and the dearest Jun 2027 at ฿7,679. These are observations, not a forecast for next year: a month that read cheap in one pass may not in the next. Use it as a starting point for comparison, not a fixed calendar.

About Beijing

Beijing (PEK) sits in China. The flight from Bangkok runs about 5.0 hours. We hold 12 monthly lows spanning a 67% range. This corridor scores 7/10 on our own catalogue demand ranking. Our catalogue lists 5 carriers on this city pair.

Beijing is the capital of China and the centre of its history and government — a vast city holding the Forbidden City, the Temple of Heaven and, beyond it, access to the Great Wall. It is a place of large scale and deep history, and a major hub for travel onward across China. For Thai travellers it works as a destination in its own right; the cooler spring and autumn months are the most comfortable for the climate.

Local time at the destination. Beijing 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.

The cheapest fare here is not the nonstop

The lowest fare we have recorded, ฿4,609, is a 1-stop itinerary with a total journey time of 16h 5m, against an average nonstop block time of 5.0 hours on the same corridor — about 11.1 hours more. The cheapest number on this page is therefore priced for a different product than the nonstop.

This is the lowest fare our feed returned for BKK–PEK, not a quoted price. It is the minimum of the record we hold for this one corridor — not the lowest value in our fare cache, not an average, not a live quote, and not a promise that a seat still exists at that number. An unusually low reading almost always traces to one carrier’s limited promotional inventory, which is gone before you reach checkout. Treat it as a reference line for how low this corridor can go, then check live pricing before deciding.

The price is attached to a date. Our most recent low is tied to a 2026-09-28 departure. Fares on international corridors move with the day of week and the holiday calendar more than most travellers expect, and shifting the date by one or two days usually does more for the price than switching airline. If your dates are fixed, read this number as a theoretical floor rather than something you will be offered.

Passenger rights on BKK–PEK

Our catalogue lists 5 carriers on this city pair. Departures from Thailand fall under Thailand CAAT; the return from Beijing 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.

FAQ

Which airlines fly Bangkok to Beijing?

The BKK-PEK route is operated by Thai Airways, Air China, Hainan Airlines, China Southern and Spring Airlines. Compare baggage, alliances and fares in the table above.

How long and how often is the BKK-PEK flight?

Block time is ~5.0h, with ~28 flights per week across all carriers.

When is BKK-PEK 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–PEK, 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–PEK 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.

Why does the cheapest ticket take longer than the 5.0-hour block time?

Because the lowest fare we recorded is a 1-stop itinerary with a total journey time of 16h 5m, not a nonstop. Filter to nonstop and compare the price again.
