Booking checklist
- Compare the Iberia nonstop vs one-stop options — the premium is often modest.
- For summer book 2–4 months ahead; winter 6–8 weeks is fine.
- No visa needed for US tourists (Schengen 90/180 rule) — just a valid passport.
- Allow 2+ hours for connections at Barajas; it is a big airport.
- Buy your EU eSIM before you fly — one SIM covers Spain and onward countries.
- Book onward intra-Europe flights early for the cheapest fares.
- Plan dinners late (9–10pm) — that is when Madrid actually eats.
Fare tips for this route
- The Iberia nonstop premium over one-stops is usually modest — price both, but do not assume the connection is much cheaper.
- Spain uses the euro. Get euros from ATMs on arrival (decline the conversion offer); airport exchange booths are the worst rate in the building.
- US passport holders do not need a visa for Schengen stays up to 90 days in any 180-day period.
- Madrid’s Barajas airport is huge — allow 2+ hours for international connections, especially terminal changes.
For summer (Jun–Aug), book 2–4 months ahead. For winter (Nov–Feb), 6–8 weeks is often enough. Shoulder season (Apr–May, Sep–Oct) rewards 2–3 months ahead with the best balance of weather and fares.
