Flights Bangkok to Jakarta (BKK-CGK): Airlines, THB Fares

Bangkok to Jakarta connects Thailand with the capital of Indonesia, a route weighted toward business travel between two of Southeast Asia’s largest economies, alongside tourism and regional family movement. At around 42 flights a week it is frequent and well served.

Block time is about 3.7 hours. Jakarta is a vast metropolitan area and a major hub in its own right, so the route carries both city visitors and travellers using Jakarta as a connecting point across the Indonesian archipelago.

Corridor profile

The BKK–CGK corridor runs about 42 departures a week across 5 carriers, with an average block time of 3.7 hours, and the lowest fare the feed returned for this route is ฿4,349. 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. 42 weekly departures is ~6 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–CGK runs 7–30 kg across the 4 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.

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

5 carriers operate BKK–CGK — 2 full-service and 2 low-cost. Alliances present on the route: SkyTeam, 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 ฿4,349 on a 2026-09-08 departure.

Five carriers fly BKK-CGK: Thai Airways and Garuda Indonesia on the full-service side, with Thai AirAsia, Thai Vietjet and Indonesia AirAsia covering the low-cost end. The full-service carriers include checked baggage and a fuller cabin; the low-cost carriers price the base seat low and charge 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. SkyTeam, 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.

Monthly market-low pattern (THB)

Fare trends

Between 2026-W20 and 2026-W31 we captured the BKK–CGK low 8 times, ranging ฿4,063 to ฿6,008 — a 48% spread. The cheapest reading fell in week 2026-W30, and from first capture to last the low moved down 19%.

BKK-CGK fares stay competitive given the frequency, rising around the year-end holidays, the Indonesian holiday periods and the Thai school breaks. For those peaks, six to ten weeks of lead time is sensible. Outside them, the low-cost carriers’ early-released fares are the cheapest seats, and three to six weeks usually finds a good THB price. Mid-week departures undercut weekends.

The price is attached to a date. Our most recent low is tied to a 2026-09-08 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.

Seasonality & best time to book

Our catalogue lists 5 carriers on this city pair. BKK–CGK 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–Jakarta 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 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.

The booking window matters more than the booking day. On a 3.7-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.

About Jakarta

Our catalogue lists 5 carriers on this city pair. Jakarta (CGK) sits in Indonesia, uses IDR, and the visa position we record for a Thai passport is: visa-free 30 days (ASEAN). The flight from Bangkok runs about 3.7 hours. Jakarta — ASEAN, visa-free 30 days

Jakarta is Indonesia’s capital and the centre of one of the world’s largest metropolitan areas — a sprawling, fast-moving business city rather than a conventional tourist destination. For most travellers from Bangkok it is a place of work and meetings, or a connecting point: Jakarta’s airport feeds onward routes to Bali, Yogyakarta and the wider archipelago. Travellers passing through often build in a short city stay rather than treating Jakarta as the main trip.

Visa position for a Thai passport. Our data records: visa-free 30 days (ASEAN). That status attaches to the passport’s nationality, not to the airline or the fare. Travelling companions on other passports can sit under entirely different conditions on the same flight — check each person separately before booking as a group.

The cheapest fare here is not the nonstop

The lowest fare we have recorded, ฿4,349, is a 1-stop itinerary with a total journey time of 22h 40m, against an average nonstop block time of 3.7 hours on the same corridor — about 19.0 hours more. The cheapest number on this page is therefore priced for a different product than the nonstop.

Who holds the price matters. In our most recent capture the low sat with the agency Авиасейлс rather than the airline’s own site. Changes and refunds on an agency ticket have to go back through that agency first, and when a flight is cancelled the re-route is generally slower than holding the ticket directly with the carrier. A few hundred baht of saving is not automatically worth it if your itinerary has little slack.

Price the hours before you decide. The extra 19.0 hours do not simply vanish; they turn into airport meals, a paid lounge, or a hotel night if the connection runs overnight. Add those back and the saving that looked attractive is usually thinner than it appeared. The question is not how much cheaper it is, but how much cheaper per hour surrendered.

Passenger rights on BKK–CGK

Our catalogue lists 5 carriers on this city pair. Departures from Thailand fall under Thailand CAAT; the return from Jakarta falls under Indonesia Kemenhub (PM 89/2015). 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 Indonesia Kemenhub (PM 89/2015), 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

Which airlines fly Bangkok to Jakarta?

The BKK-CGK route is operated by Thai Airways, Garuda Indonesia, Thai AirAsia, Thai Vietjet and Indonesia AirAsia. Compare baggage, alliances and fares in the table above.

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

Block time is ~3.7h, with ~42 flights per week across all carriers.

When is BKK-CGK cheapest to book?

The lowest fare our feed returned for this route is ~฿4,063. 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–CGK, 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–CGK flight is cancelled, who is responsible?

The destination sits with Indonesia Kemenhub (PM 89/2015), 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 3.7-hour block time?

Because the lowest fare we recorded is a 1-stop itinerary with a total journey time of 22h 40m, not a nonstop. Filter to nonstop and compare the price again.
