I actually went through this exact process a few weeks ago, so here’s my firsthand experience on how to modify a Spirit Airlines booking — hopefully it saves someone else the headache I had!

I had booked a round-trip flight from Orlando to Las Vegas with Spirit Airlines, but then my plans changed at the last minute. I tried doing everything online first, and while Spirit’s website is decent, I found it a bit tricky to navigate under pressure. Here’s what I learned step-by-step:

Step 1: Log in to your Spirit account – Go to Spirit.com and log in using your email and password. Once you’re in, head to the “My Trips” section.

Step 2: Retrieve your booking – You’ll need your last name and confirmation code (the six-character code in your booking email). Once entered, your flight details will pop up.

Step 3: Click “Modify” – This is where you can make changes like adjusting your travel dates, adding baggage, or changing your seat. Spirit charges a modification fee depending on how close you are to the travel date — I changed mine two days before and paid a small fee plus the fare difference.

Step 4: Confirm and pay any difference – Spirit will show you the new total. If you’re good with it, just confirm and make the payment. You’ll get a new confirmation email within minutes.

Now, here’s my honest advice: if you’re in a rush, skip the website hassle and call Spirit’s customer service directly at 844-734-0813. When I called, I got through to a rep in about five minutes, and she handled everything — from changing my date to updating my baggage options. It was so much faster than clicking through the site.

Step 5: Double-check your email – Spirit sends an updated itinerary right away. I always recommend cross-checking your new flight details before closing the call or logging off.

In my case, I was worried I’d lose my fare or get hit with a huge fee, but the rep explained everything clearly and even helped me find a slightly cheaper flight time. So honestly, I came away impressed.

Pro tip: If you booked through a travel agency or third-party site, you might still want to call 844-734-0813 because Spirit can usually handle it directly, even for third-party bookings.

So yeah, modifying a Spirit Airlines flight isn’t hard once you know the right steps — and a quick phone call can save you a ton of stress.
