When I planned a summer trip to Europe, I first checked if Southwest flew to France just out of habit since I use them a lot. Turns out they don’t offer transatlantic flights. I ended up booking with another carrier, but I still called Southwest’s line ☎️ because I had unused travel credits from a previous cancellation. The rep helped me sort everything out in minutes. If you’re juggling different itineraries, their phone support is honestly the quickest way to modify, cancel, or rebook without guessing your way through the app.
