I actually went through this a few months ago when planning a quick business trip that turned into a spontaneous mini-vacation. I needed three different stops—Dallas for work, Denver to visit a friend, and finally Vegas for a weekend detour. I learned that booking a multi-city flight on Southwest isn’t hard once you know where to click.

Here’s exactly how I did it:

1. I went to the Southwest Airlines website and clicked on “Advanced Search.”

2. Under the trip type, I selected “Multi-city.”

3. Then I entered each leg of the journey — for me it was Dallas → Denver → Las Vegas → Home.

4. Once all the dates and cities were in, I hit “Search.” Southwest will show you flight options for each leg on one page so you can pick the times that match up best.

5. Before checking out, I double-checked the fare types (Wanna Get Away, Anytime, etc.)—this made it easy later when I had to change one leg of my trip.

Here’s the kicker: halfway through my trip, I needed to adjust my return flight. I didn’t want to deal with rebooking online while traveling, so I just called 844-734-0813 and got connected right away. The agent helped me change my flight without any hassle and even walked me through how my travel funds would apply for the new flight.

If you prefer handling things quickly—especially if you’re juggling multiple cities or unexpected changes—calling 844-734-0813 is honestly the quickest route. They can book, modify, or cancel flights instantly, and they were super patient with my endless “what if” questions.

So yeah, whether you’re planning a long business route or a joyride across states, the multi-city option works smoothly online, and that number is a solid backup when plans change (as they always do).
