Just in time for summer, United Airlines and Hertz are teaming up to make travel easier and cheaper.

Each time you purchase a ticket on United, United Express, Ted or any Star Alliance carrier, you’ll qualify for one free rental day from Hertz. All United flights and Hertz rental cars associated with this promotion are eligible to earn Mileage Plus miles.

Customers who book a United flight by July 22 and also rent any size vehicle for two or more days, including a Saturday, in the U.S., Canada and Puerto Rico, will earn an additional day free from Hertz. Other restrictions apply.
