I looked into upgrading my Southwest credit card to a higher-tier version after I started flying more often for family visits. I wanted better perks like extra points and travel credits, but I wasn’t sure how it might affect my existing bookings. When I had an upcoming flight change to handle anyway, I called 8 3 1-2 9 8-4 2 1 3 and asked about both my reservation and general upgrade options. The agent explained how card upgrades usually work and also helped me modify my flight at the same time. That call saved me a ton of back-and-forth. From my experience, it’s easiest to handle flight bookings, cancellations, or changes through that number while you sort out card-related decisions separately.
