Frequently asked questions

What happens if I need to cancel my Southwest car reservation?
Our Customer Service Portal has all the info about this. In almost all cases, complete refunds are available if a reservation is canceled more than six hours before collecting the car. It's a good idea to read your rental policy to see if there are any exemptions.

How old do you have to be to rent a car in Southwest?
In most cases, the rules are 21 years and over in Southwest. Be aware that most outlets have a young driver surcharge. Check before you sign up, as rules may differ between rental car providers. Keep in mind that if you're planning to rent a specialty vehicle or a large car like a premium SUV, rules may require drivers to be older than 21.
What do you need to rent a car in Southwest?
Your driver's license and a credit card in the same name are essentials. Don't want to take out the company's insurance plan? In that case, you're also likely to need proof of your own coverage. Rules may differ from rental company to rental company, so read through your policy.
Can I rent a car for a month or longer in Southwest?

Where can I find a Southwest car rental if I am younger than 25?
Whether or not you can rent a vehicle if you're under 25 years in Southwest often depends on the rental provider you select. Some places apply a surcharge for customers between 21 and 24 years of age, but others may not apply any additional fees for this age bracket. It'd be good to go through the terms and conditions of your chosen car company to avoid excessive charges when picking up your keys.
What insurance should I choose for my car rental in Southwest?
Get your road trip off to a good start by selecting Expedia's collision protection. While there are many types of insurance, this is one you should have. It provides primary coverage for collision damage, vandalism and theft up to $35,000, as well as 24-hour emergency assistance. Don't wait until you reach the rental desk to insure your wheels. Opt in to collision protection while reserving your Southwest ride with Expedia and save money and time.
