Almost every guide to getting from Adolfo Suárez Madrid-Barajas into the city tells you
the Metro is the cheap option. On the published fares it is not. It is roughly twice the price of
the train sitting in the same airport.
The reason is a supplement that does not apply to the other rail option, and it is worth two
minutes of arithmetic before you land.
The four ways in, and what each is reported to cost
| Option | Reported fare | Journey | Where it drops you |
|---|---|---|---|
| Cercanías train | About €2.60 | Roughly 25–30 min to Atocha | Atocha and Chamartín, on the national rail network |
| Metro, Line 8 | About €4.50–5.00 including the airport supplement | Around 30–45 min depending on where you get off | Nuevos Ministerios, then anywhere on the Metro |
| Express bus 203 | About €5.00 | Around 30 min | Cibeles and Atocha — runs 24 hours |
| Taxi | €33 flat, to anywhere inside the M-30 | Traffic-dependent | Your door |
are revised periodically and the taxi flat rate is set by the city — confirm before you
travel.
Why the Metro is not the cheap one
Madrid charges an airport supplement on Metro journeys starting or ending at the airport
stations. A single Metro ticket plus that supplement is commonly reported at €4.50 to €5.
Cercanías carries no equivalent surcharge, and is reported at around €2.60.
So the cheapest rail option is the one most people never see. The catch is
where it runs from: Cercanías serves Terminal 4. If you land at T1, T2 or T3 you have to
take the free inter-terminal shuttle first, which adds time and is exactly why so many arrivals
default to the Metro escalator in front of them. If you are landing at T4 anyway, there is no good
reason to pay double.
The point where the taxi wins
The €33 taxi fare is flat — a fixed price to any destination inside the M-30
ring, not a meter. That changes the comparison completely as soon as you are not travelling alone,
because it is the only option here that does not multiply by the number of people.
| Party size | Cercanías | Metro | Express bus | Taxi (flat €33) |
|---|---|---|---|---|
| 1 person | €2.60 | ~€4.50–5 | €5 | €33 |
| 2 people | €5.20 | ~€9–10 | €10 | €33 |
| 3 people | €7.80 | ~€13.50–15 | €15 | €33 |
| 4 people | €10.40 | ~€18–20 | €20 | €33 — about €8.25 each |
only — it assumes adult single fares and a destination inside the M-30.
Public transport is still cheaper at every party size on these numbers. But the gap narrows
sharply: at four people the taxi is about €8.25 a head against €5 on the bus, for a door-to-door
ride with luggage. That is a different trade-off from the one you face alone, where the taxi costs
more than twelve times the train.
The fourth option, priced against the taxi
A pre-booked private transfer sits alongside the taxi rather than the train. The fee is agreed before you fly rather than set at the rank, the driver watches the flight if it slips, and you are met inside the terminal instead of finding the queue. Welcome Pickups prices it at roughly what a taxi from the line costs, so it is not competing with €2.60 Cercanías and does not pretend to.
It earns its place in one situation: arriving with luggage, with small children, or at an hour when working out which terminal the free shuttle leaves from is the last thing you want to do. If you are landing at T4 with a cabin bag, take the train. Check transfer prices for your arrival.
Two things the fare table does not tell you
The flat fare has a boundary. The €33 applies within the M-30. A destination
outside that ring is metered, and the number you were quoted no longer applies. Check where you are
staying against the ring road before you assume the flat rate covers it.
Only one of these runs all night. The Express bus 203 operates 24 hours. Metro
and Cercanías do not. On a late arrival the comparison collapses to two options, and the
€5 bus stops being the third-cheapest choice and starts being the only one that is not a
taxi.
Fares and journey times compiled in 2026 from published guidance including
Madrid’s official visitor site and
published airport bus information.
Fares are revised periodically, the airport supplement and the taxi flat rate are both set by the
city and have changed before, and terminal-by-terminal access differs. Treat the per-person table
as arithmetic on published figures rather than a quote, and confirm the current fare before you
travel.
