Official site: iberia.comIberia's hub at Madrid is the main European connecting point for Latin America, which is why it appears so often on itineraries between the United States and South America that do not route through a US hub. Its transatlantic network to the US is smaller but well established.
The airport detail that matters is Terminal 4 and its satellite, T4S. They function almost as separate buildings connected by an internal train, and a connection between them or between T4 and T1–T3 requires more time than the published minimum suggests.

How Iberia baggage works
Allowance follows cabin and fare tier, with the entry-level fares typically excluding a checked bag on shorter routes. Iberia Plus and oneworld status add entitlements.
Long-haul tickets generally use a piece system with a per-bag weight ceiling.
Iberia shares a group with British Airways, so a booking with one may be operated by the other with different rules. Confirm against your booking on iberia.com.
Check-in
Online check-in typically opens 24 hours before departure.
At Madrid, identify the terminal before you travel. T4 and T4S handle most Iberia long-haul, and reaching the satellite involves an internal train.
Boarding
Boarding is by group according to cabin and status, with oneworld priority applying.
Some Madrid departures use remote stands with a bus transfer, which lengthens boarding.
Before you fly Iberia
T4 and T4S are effectively separate
A connection between the main terminal and the satellite means an internal train ride. Build in more time than the minimum connection suggests.
Madrid is the strong option for Latin America
If you are heading from the US to South America, an Iberia routing through Madrid can be competitive and sometimes more comfortable than a US-hub connection.
Check whether BA or Iberia is operating
The two are in one group and codeshare heavily. The operating carrier determines the cabin product and some of the rules.

FAQ
Iberia — common questions
General guidance only. Iberia sets these policies and can change them, so confirm anything that affects your trip at iberia.com.
Is connecting at Madrid Barajas difficult?
It is straightforward within a terminal and slower between them. T4 and its satellite T4S are linked by an internal train, and T1 to T3 are a separate group reached by shuttle. Most Iberia long-haul uses T4 or T4S, so the question is usually whether your connection stays within that pair. Allow more than the published minimum if it does not.
Does an Iberia fare include a checked bag?
It depends on the fare tier and route, with the cheapest tiers on shorter routes typically hand baggage only and long-haul tickets generally including checked baggage on a piece system. Check what your specific fare includes on iberia.com before comparing it against another carrier's standard fare.
Are Iberia and British Airways the same company?
They are separate airlines within the same parent group, and they codeshare extensively. A ticket bought from one can be operated by the other, which affects the cabin product, the baggage rules and which terminal you use. Check the operating carrier on your booking rather than the name you bought from.
