If you are arriving on a flight to Milan Linate airport and you want to rent a car, you have a few options.
A number of major car rental companies operate from Linate airport. These include Avis, EasyCar, Europcar, Hertz, National, Sixt and Thrifty, which all have car hire offices in the arrivals halls.
The offices are open during normal airport hours, but some car rental operators will charge extra if you arrive outside of normal hours. Make sure to check when booking to avoid extra fees. In fact, make sure to read the small print carefully before signing any car rental contract, as there may be charges for things that you are not anticipating, and what seems like a good deal at first could end up costing more than you think.
If you want to make sure you get a deal, there are plenty of car rental voucher codes and special offers online that can help you get a discount on your car.
Additionally, city center car rentals tend to be cheaper than airport car rentals due to airport taxes, so if you can get into the city cheaply, you can often get a much better price. The cheapest way to get into the city is by bus, but you can also take a taxi into Milan.
