Bottom line: fly into Linate (LIN) for short-haul European flights and Malpensa (MXP) for long-haul international ones. Linate sits just 8 km from the centre — the M4 metro reaches San Babila in about 12 minutes for €2.20, and a taxi runs roughly €20-30, making it the fastest, most convenient option. Malpensa, about 50 km outside the city, is Milan's main international hub; the Malpensa Express reaches Cadorna in 38 min / Centrale in 51 min for €15, with a fixed €110 taxi or €5-10 shuttle bus (50-60 min). A third choice, Bergamo (BGY), mostly serves low-cost carriers and is closer if you're headed to Lake Como or the mountains. Rule of thumb: short-haul or a quick city arrival → LIN; long-haul international → MXP.
