Unless you rented a car, we would recommend booking a taxi through the airport!
Once you are done with customs, a taxi stand can be found to the right of the double doors. All you need is to show the address of your destination, and they will assign you a driver.
There is usually a line of taxis waiting outside of the airport.
Uber is also widely used in Guadalajara, although we still recommend using the taxis as they have priority over the airport.
