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

Don Mueang to Jakarta is the low-cost route on the Bangkok–Jakarta corridor, flown from Bangkok’s budget-airline airport. With around 21 flights a week, it offers an economical link to the Indonesian capital for tourists, budget business travellers, and passengers connecting onward across the Indonesian archipelago.

Block time is about 3.7 hours. The route appeals to travellers who want the lowest fare to Jakarta, and to those for whom Don Mueang, the low-cost hub in northern Bangkok, is simply the easier airport to use.

Corridor profile

The DMK–CGK corridor runs about 21 departures a week across 2 carriers, with an average block time of 3.7 hours, and the lowest fare the feed returned for this route is ฿5,618. The frequency figure counts every carrier on the route combined, not any single airline.

“Direct” and “nonstop” are not synonyms. The 3.7-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 6/10. 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 DMK–CGK runs 7 kg across the 1 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.

Some items are not measured in kilograms alone. Sports equipment, instruments, pushchairs and oversized boxes are handled under size and item-type rules rather than the kilogram figure in the table. Several categories need advance notice because hold space is finite, and lithium batteries carry separate safety requirements that bar them from checked baggage. Check all three before travel day — at the desk the only remaining options are abandon it or ship it separately.

An infant fare is not a free seat. We record AirAsia (Malaysia)‘s infant fare at about 15% of the adult fare. That rate is for a lap infant with no seat of its own. Want a separate seat or a car seat and it becomes a child fare, priced as a share of the full fare, and the infant’s own baggage entitlement is usually far smaller than an adult’s. Strollers normally travel outside the weight allowance, but the policy differs by carrier — confirm before you fly.

Airlines on this route

2 carriers operate DMK–CGK — predominantly unbundled. No major-alliance carrier appears on this route. 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 ฿5,618 on a 2026-09-24 departure.

Two low-cost carriers fly DMK-CGK: Thai AirAsia and Indonesia AirAsia, both part of the AirAsia group, operating from their Don Mueang and Jakarta bases. Both price the base seat low and sell checked baggage, seat selection and meals separately. On a route of nearly four hours, count the baggage you need into the total — the all-in THB cost, not the headline fare, is what decides value.

Carrier count is not year-round competition. Some operators fly this corridor seasonally or on selected weekdays. In a week where only one is genuinely selling, the fare behaves like a monopoly fare. The fastest check is how many carriers actually quote your dates, not how many have ever served the route.

Fare trends

Between 2026-W20 and 2026-W31 we captured the DMK–CGK low 5 times, ranging ฿5,390 to ฿6,310 — a 17% spread. The cheapest reading fell in week 2026-W20, and from first capture to last the low moved up 4%.

DMK-CGK fares are competitive, kept low by the AirAsia-group operation and the corridor’s steady demand. They lift around the year-end holidays, the Indonesian holiday periods and the Thai school breaks — six to ten weeks of lead time is sensible for those windows. Outside them, the early-released fares are the cheapest seats, and three to six weeks usually finds a good THB price.

Who holds the price matters. In our most recent capture the low sat with the agency Aviakassa 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.

Seasonality & best time to book

Our catalogue lists 2 carriers on this city pair. DMK–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.

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.

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 Jakarta

Our catalogue lists 2 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, the destination of this route, is Indonesia’s capital and the centre of one of the world’s largest metropolitan areas — a vast, fast-moving business city rather than a conventional tourist stop. For budget travellers from Bangkok it is most often a place of work, or a connecting point: Jakarta’s airport feeds low-cost routes onward to Bali, Yogyakarta and the wider archipelago, which is much of what this corridor serves.

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.

The cheapest fare here is not the nonstop

The lowest fare we have recorded, ฿5,618, is a 2-stop itinerary with a total journey time of 22h 45m, against an average nonstop block time of 3.7 hours on the same corridor — about 19.1 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 Aviakassa 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 19.1 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 DMK–CGK

Our catalogue lists 2 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 DMK-CGK route is operated by AirAsia (Malaysia) and Batik Air. Compare baggage, alliances and fares in the table above.

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

Block time is ~3.7h, with ~21 flights per week across all carriers.

When is DMK-CGK 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 DMK–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 DMK–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 2-stop itinerary with a total journey time of 22h 45m, not a nonstop. Filter to nonstop and compare the price again.
