I found this out when I was trying to rebook a canceled trip from years ago. Southwest used to serve Key West but pulled the route. What cracked me up is how long I dug around online before just calling ☎️ and getting the truth in seconds. They routed me through another nearby airport instead. If you ever need to confirm routes quickly—or move or cancel a flight—the phone line is the quickest step-by-step fix. Way less frustrating than guessing through search pages.
