Madrid to Bangkok is a long-haul route with a genuine choice: Iberojet now flies non-stop in around 12¾ hours, or you can save on a connection. Checking every return fare on sale, the gap is modest — connections start at €463 against €580 for the Iberojet direct — so the non-stop is well worth pricing. This guide covers who really flies the route, what a return actually costs in euros, and when to book.
Route: Madrid (MAD) → Bangkok Suvarnabhumi (BKK)
Distance: approximately 10,250 km (6,370 miles)
Non-stop flight time: about 12h 45m eastbound
Direct flights: Yes — Iberojet flies non-stop from Madrid on an Airbus A350, currently around twice a week, at €580 and up in our fare data. Frequency is limited, so one-stop options run far more often — and the cheapest of them are Chinese and Gulf routings from €463, not the Doha or Istanbul connections usually recommended.
Fares from Madrid to Bangkok (EUR)
Bangkok is a year-round destination, but fares swing with Thailand’s seasons. The cool, dry high season (November–February) and the Christmas/New Year peak are the priciest; the green season (June–October) is the cheapest. The figures below are typical economy return fares in euros — the lowest are usually one-stop itineraries, with the Iberojet non-stop sitting toward the higher end.
| Month | Demand | What to expect |
|---|---|---|
| January | — | high |
| February | — | high |
| March | — | medium-high |
| April | — | medium (Songkran) |
| May | — | low |
| June | — | low |
| July | — | medium (school holidays) |
| August | — | medium |
| September | — | low |
| October | — | low-medium |
| November | — | high |
| December | — | very high |
Checked against every return fare on sale as we write, a typical fair price is roughly €540–€570 — the connecting median is €532, so that band is right. The floor is €463 on a Hainan connection, so a fare under about €510 is a genuinely good one and there is nothing in the three or low four hundreds to wait for. The Iberojet non-stop starts at €580 — above the cheapest connections, but by roughly €120 rather than the several hundred a 12-hour direct usually commands, which makes it unusually good value if the dates work.
Airlines on this route
Non-stop (about 12¾ hours):
- Iberojet — the only non-stop Madrid → Bangkok service, flown on a modern Airbus A350 with economy and business cabins, currently about twice weekly. Check the exact days when you plan, as the schedule is seasonal.
One-stop (usually the cheapest, about 15–19 hours total):
- Qatar Airways via Doha — frequent, well-rated, and often the best-value premium economy.
- Emirates via Dubai — several daily departures from Madrid and a strong economy product.
- Turkish Airlines via Istanbul — a short first hop and typically among the lowest headline fares.
- Etihad via Abu Dhabi and other Gulf carriers — competitive on price, with a single stop.
Because the one-stop carriers compete hard, they usually undercut the non-stop by €50–€150. If time matters more than money, book the Iberojet non-stop; if price is the priority, a single stop through Doha, Dubai or Istanbul is the sweet spot.
When to book & how to save
- Book 2–4 months ahead for the best balance of price and choice; long-haul fares to Bangkok rarely get cheaper in the last few weeks.
- Avoid the peaks if you can: Christmas/New Year and Thai New Year (Songkran, mid-April) are the most expensive and busiest.
- Fly in the green season (June–October) for the lowest fares — it rains in short bursts, not all day, and the crowds thin out.
- Weigh the non-stop against the layover: the Iberojet direct saves hours but runs only a couple of days a week, so book early if the dates suit you.
- Check checked-bag rules: Gulf and full-service carriers usually include 25–30 kg to Bangkok; the lowest “light” fares may not, so compare the all-in price.
Arriving in Bangkok
Most international flights land at Suvarnabhumi (BKK), about 30 km east of the city. The fastest way in is the Airport Rail Link to Phaya Thai (around 45 minutes, well under €2), or a metered taxi from the public rank (roughly €8–€12 to the centre, plus tolls). A handful of budget and regional flights use the older Don Mueang (DMK) airport to the north — check which one your ticket uses, as they’re on opposite sides of the city.
Frequently asked questions
How long is the flight from Madrid to Bangkok?
The Iberojet non-stop takes about 12 hours 45 minutes eastbound (Madrid to Bangkok), and a little longer coming back against the winds. One-stop itineraries through Doha, Dubai or Istanbul typically take 15 to 19 hours in total, depending on the connection.
Are there direct flights from Madrid to Bangkok?
Yes. Iberojet flies non-stop from Madrid to Bangkok on an Airbus A350, currently about twice a week. It’s the only non-stop option, so if the days don’t suit you or you’d rather save money, one-stop flights with Qatar Airways, Emirates or Turkish Airlines are usually cheaper.
How much does it cost to fly from Madrid to Bangkok?
A typical economy return runs about €500–€620, with the whole sample spanning €463–€1,640. The best connections start at €463 on Hainan, with Etihad at €532–€558; the Iberojet non-stop starts at €580. The December peak and Songkran push everything toward the top.
What is the cheapest month to fly from Madrid to Bangkok?
June and September are usually the cheapest. In the dates we could price, connecting returns started at €463 and the Iberojet non-stop at €580. Avoid December, early January and mid-April (Songkran), which are the busiest and most expensive.
Which airlines fly from Madrid to Bangkok?
Non-stop: Iberojet, on an Airbus A350, from €580. One-stop, cheapest first in our fare data: Hainan Airlines via its Chinese hubs (€463–€535, the cheapest on the route), Etihad via Abu Dhabi (€532–€558), Turkish Airlines via Istanbul (€675) and Qatar Airways via Doha (€618–€1,007). Emirates also sells the route but did not appear among the cheapest fares when we checked. The connections run far more frequently than the twice-weekly non-stop. Check transit-visa rules for your passport before booking a Chinese connection.
Which airport do I fly into in Bangkok?
Almost all international flights land at Suvarnabhumi (BKK), Bangkok’s main airport. Some budget and regional services use Don Mueang (DMK) instead — they’re on opposite sides of the city, so check your ticket before you book onward transport.
How far in advance should I book Madrid to Bangkok flights?
Aim to book 2 to 4 months ahead. Long-haul fares to Bangkok tend to rise as departure approaches, especially around the November–February high season and the Christmas peak, so early booking almost always wins.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) are usually a little cheaper than Friday–Sunday, and flying out and back on weekdays can save €30–€80 on a return. Being flexible by a day or two is one of the easiest ways to cut the fare.
