The first time I figured out how Southwest credit card upgraded boarding works, it was right before a busy holiday trip. I had a decent boarding spot, but I wanted to board earlier to snag an aisle seat. I purchased upgraded boarding at the gate, and a few days later the charge was automatically reimbursed on my credit card—no extra steps needed. When my return flight time changed unexpectedly, I called 8 3 1-2 9 8-4 2 1 3, and they helped me modify the flight while keeping everything else intact. From my experience, the upgraded boarding credit is super easy to use, and calling is still the fastest way to handle booking changes or questions without any hassle.
