What upgrade options does Spirit Airlines offer?
Spirit Airlines offers Bid Upgrade.
How does Spirit Airlines's bid (offer) upgrade work?
You name an amount — within a range shown for your booking — to move up to a higher cabin. It's an offer, not a fixed price: you're only charged if Spirit Airlines accepts it. If your offer isn't accepted you pay nothing and keep your original seat.
How do I check if my Spirit Airlines booking can be upgraded?
Check your specific booking with Upgrade Agent: enter your booking reference and last name and you'll see the upgrade options and price ranges available on your flights — you don't need to dig through Spirit Airlines's website. Visit Spirit Airlines's official upgrade page and enter your booking reference and last name to see available upgrade offers: https://upgrade.plusgrade.com/offer/Spirit
Who is eligible for a Spirit Airlines upgrade?
Eligibility depends on your fare type, route, and how close to departure you are — not every fare or flight qualifies, and offers usually open within a window before departure. The reliable way to know is to check your specific booking rather than assume.
When am I charged for a Spirit Airlines upgrade?
Only if your offer is accepted. With bid upgrades the charge happens when the upgrade is confirmed — typically in the days before departure. If your offer isn't accepted, there's no charge.
How will I know if my Spirit Airlines upgrade offer was accepted?
Spirit Airlines notifies you — usually by email — if your offer is accepted, typically shortly before departure. Until then your original booking stands, and you can review your offer's status where you submitted it.
Can I change or cancel my Spirit Airlines upgrade offer?
A pending offer can usually be changed or cancelled any time before it's accepted, from the page where you submitted it. Once an offer is accepted and charged, the upgrade is confirmed.
How much does a Spirit Airlines upgrade cost?
There's no fixed price — you offer within a range shown for your booking, which varies by route, cabin, and demand. You choose where in that range to bid; higher offers can have a better chance of being accepted, though the exact acceptance formula isn't published.
Can I use Free Spirit points or miles for a Spirit Airlines upgrade?
Spirit Airlines's loyalty program is Free Spirit. Depending on the route and the offer shown on your booking, upgrades may be payable with points/miles as well as cash — the options available appear when you check your specific booking.
Can I change or cancel my Spirit Airlines upgrade bid after submitting it?
Yes — a Spirit Airlines upgrade bid can be changed or cancelled any time until Spirit Airlines makes its decision. Once a bid is accepted it's final and your card is charged. To update or withdraw it, use Spirit Airlines's Manage My Booking / offer page, or check your booking here (booking ••••••e + last name) and I can help you modify or cancel it.
When is my card charged for a Spirit Airlines upgrade bid?
Only if your bid is accepted. Submitting a Spirit Airlines upgrade bid authorizes your card for the bid amount, but nothing is charged unless Spirit Airlines accepts it — if the bid is declined or expires, the authorization is released and you pay nothing, keeping your original cabin. If it's accepted, the card you provided is charged the amount you offered and your upgrade is confirmed.
When will I find out if my Spirit Airlines upgrade bid was accepted?
Spirit Airlines decides upgrade bids before your flight — often close to departure, once the operator knows how much cabin space is left. You'll be notified by email either way at the address on your offer. You don't need to keep checking, but you can see your bid's current status any time by checking your booking here (booking ••••••e + last name) or on Spirit Airlines's Manage My Booking page.
