Budget airlines keep competition fierce from Madrid-Barajas (MAD). These city pairs regularly show round-trip fares under €80 when booked a few weeks ahead in off-peak months.
Standout value destinations
- Lisbon (LIS) — frequent sales, 1h flight
- Porto (OPO) — often cheaper than Lisbon with similar appeal
- Milan (BGY/MXP) — watch both airports; Bergamo can be €20 less
- Rome (FCO/CIA) — Ciampino often wins on price
- Athens (ATH) — shoulder season (Apr–May, Oct) is the sweet spot
How we find these fares
Mintravo pulls live prices from partner APIs — not cached estimates. Check our Explore section for round-trip deals from Madrid updated in the last 72 hours.
Don't forget ground costs
A €29 flight to a secondary airport plus a €35 transfer can lose to a €55 flight to the main city. Always compare total trip cost, not just the fare box.
