I actually looked this up last year when I was planning a quick getaway to Costa Rica. Southwest does fly there, but only to specific airports and only on certain days. When I booked, I messed up my dates and had to change the flight the same evening. Luckily, Southwest’s no-fee change policy saved me. I just hopped onto their site, hit “Change Flight,” and it updated instantly. If you ever need fast booking or last-minute changes, calling their help line ☎️ is honestly the quickest way—they fixed something for me in less than five minutes.
