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 money on a one-stop itinerary through the Gulf or Istanbul. This guide covers who flies the route, what a fair return fare looks like in euros, and when to book for the best price.
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. Frequency is limited, so one-stop options through Doha, Dubai or Istanbul are usually cheaper and run far more often.
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 | Typical return (economy) | Demand |
|---|---|---|
| January | €520 – €680 | high |
| February | €480 – €620 | high |
| March | €440 – €580 | medium-high |
| April | €440 – €600 | medium (Songkran) |
| May | €400 – €520 | low |
| June | €380 – €500 | low |
| July | €420 – €560 | medium (school holidays) |
| August | €430 – €560 | medium |
| September | €380 – €490 | low |
| October | €400 – €520 | low-medium |
| November | €480 – €640 | high |
| December | €600 – €800 | very high |
Reference points from our own deal tracking: a strong one-stop fare lands around €380–€440 return, a typical fair price is roughly €540–€570, and anything under about €440 is worth booking quickly. The Iberojet non-stop has launched from around €535 return, sitting above the cheapest Gulf connections but saving you the layover.
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 €450–€680 depending on the season. The best one-stop deals dip to around €380–€440 in the green season (June–October), while the December peak and the non-stop sit toward the top of that range.
What is the cheapest month to fly from Madrid to Bangkok?
June and September are usually the cheapest, with returns from around €380. 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. One-stop: Qatar Airways (via Doha), Emirates (via Dubai), Turkish Airlines (via Istanbul) and Etihad (via Abu Dhabi), which usually offer the lowest fares and run far more frequently than the non-stop.
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.
