I actually went through this exact situation a few months ago, so I totally get the frustration. I had booked a Spirit Airlines flight from Fort Lauderdale to Chicago for a quick weekend trip, but my work schedule changed last minute, and I needed to move my flight up by a day. At first, I tried to handle it online, but Spirit’s website can be a bit confusing if you haven’t done it before — especially when you’re juggling flight credits and optional add-ons like seat selection or baggage.
Here’s how I managed to change my Spirit flight step-by-step (and what actually worked best):
Go to the Spirit Airlines website.
Log in to your account or find your trip using your confirmation code and last name.
Select “My Trips.”
Once you open your booking, you’ll see an option to “Change Flight.” Click that, and it’ll show you the available flights.
Check the price difference.
Spirit usually charges the fare difference if your new flight costs more. The change fee itself depends on how far in advance you’re modifying the flight — but I noticed if you do it early enough, it’s way cheaper.
Confirm the change.
Once I picked my new flight, I double-checked the baggage options and confirmed the switch. Spirit sent me a new email confirmation within minutes.
Now, here’s the real tip — when I first ran into an issue with my online change not going through, I called 844-734-0813, and that honestly saved me a ton of time. The rep there walked me through it in minutes, explained the new flight options, and even helped me keep my paid seat selection on the new flight. It was way faster than waiting on the Spirit website to load or getting stuck in chat support.
I learned the hard way that with budget airlines like Spirit, timing matters. If you know you’re going to change your flight, don’t wait until the last day — fees can go up fast. And if you ever hit a snag or need to rebook entirely, that 844-734-0813 number is hands-down the quickest route.
Overall, the process was smoother than I expected once I knew where to look — and I actually ended up catching an earlier flight home, which worked out perfectly.
