Frequently asked questions

What happens if I need to cancel my Southwest car reservation?
That won't be a problem. If you can cancel your rental at least six hours before the scheduled collection time, you'll most likely receive all of your money back. Be sure to read your cancellation policy as there are some exemptions. Visit our Customer Service Portal if you still have queries.
What types of cars can I rent in Southwest?
Mini, intermediate, full-size, premium ... Whatever you prefer! However, compact models are the most popular in Southwest. If you want something inexpensive and small, but not too small, this category of rental vehicle is a great choice. Driving around traffic-filled streets will be easy in one of these. Compact vehicles are slightly more spacious than economy rides and are well-suited to couples and families on a budget.

How old do you have to be to rent a car in Southwest?
Rental vehicle rules in Southwest require drivers to be 21 and older. Are you a young driver? A few surcharges and restrictions could apply. Many rental companies impose what's known as a young driver surcharge, which is an additional fee to the car rental cost. Restrictions often apply to the classes of cars young drivers can rent as well. Age limits may vary between companies, so check before booking.
What do you need to rent a car in Southwest?
Generally, all you'll need is a current driver's license and credit card in your name when picking up the keys to your vehicle. Proof of coverage may also be required if you decide to opt out of the company's insurance plan. These requirements often differ between rental companies, so it's always wise to read the fine print.

Yes, and you're sure to find your ideal set of wheels among our long-term car rental deals. Simply enter your trip details and we'll show you amazing options from numerous trusted suppliers.
Where can I find a Southwest car rental if I am younger than 25?
This will depend on the car rental companies located in Southwest. They often have different policies when it comes to minimum ages. If you've found a place that does cater to drivers under 25, be aware that extra costs may apply. Do some research into what those charges could be before booking your rental.
What insurance should I choose for my car rental in Southwest?
For a safe, stress-free journey, add Expedia's collision damage protection while booking your rental car. This insurance covers your vehicle against accident damage, vandalism and theft. It also offers 24-hour emergency help in times of need. Opt in to this insurance while finalizing your Southwest ride with Expedia and save money and time at the rental desk.
