What Spirit Membership Actually Covers

Spirit Airlines offers a paid membership program called Spirit Unlimited that bundles together fees you would otherwise pay per flight. Instead of paying $9 to check a bag, $3 to pick your seat, or $2 for a carry-on bag on each trip, members pay one annual fee and get those services included. The membership does not give you free flights, upgrades, or lounge access — it removes specific per-flight charges that Spirit charges to non-members.

The membership covers checked bags, carry-on bags, seat selection, and priority boarding on every Spirit flight you take during the membership year. You also get a checked bag on your return flight if you are flying round-trip. The cost varies depending on which tier you choose and when you purchase it, but Spirit typically offers a base tier around $70 to $100 annually, with higher tiers that add benefits like free cancellations or priority customer service.

Spirit Unlimited is worth calculating against your actual flying habits. If you fly Spirit once or twice a year and pack light, you will not recoup the membership cost. If you fly Spirit four or more times annually and check bags, the math usually favors membership. The membership applies only to Spirit flights — it does not work on partner airlines or codeshare flights.

Key Takeaways

  • Spirit Unlimited membership bundles per-flight fees (bags, seat selection, priority boarding) into one annual payment rather than charging you each time you fly.
  • The membership pays for itself if you fly Spirit at least four times per year and use the included services, but does not cover flights, upgrades, or lounge access.
  • You can purchase membership directly from Spirit Airlines' website, and the membership year runs from the date of purchase, not the calendar year.
  • Higher membership tiers add perks like free cancellations, priority customer service, and free seat selection changes, but cost more annually.
  • The membership applies only to Spirit flights under your name — you cannot transfer it to family members or use it on flights booked by someone else.

Breaking Down the Per-Flight Fees Spirit Membership Replaces

Spirit's business model charges for services that other airlines include in the base ticket price. A checked bag costs $9 to $15 per flight depending on whether you pay in advance or at the airport. A carry-on bag costs $3 per flight if you do not have a seat assignment yet (if you have already chosen a seat, the carry-on is free). Seat selection costs $2 to $15 depending on the seat location and how close the flight is.

Priority boarding, which lets you board before general boarding and get overhead bin space, costs $3 per flight. If you fly round-trip, you pay these fees on both the outbound and return flight. A member flying round-trip with one checked bag, one carry-on, and seat selection would pay roughly $40 to $50 in fees per round-trip without membership. Fly that route four times in a year and you have spent $160 to $200 on fees alone — which exceeds the annual membership cost.

The membership does not waive all fees. Baggage fees for items over the weight limit, fees for changing flights, and fees for special services like unaccompanied minors or pet transport still explore. Read the membership terms on Spirit's website to see the current full list of what is and is not included.

How to Purchase Spirit Unlimited and When It Starts

You purchase Spirit Unlimited directly from Spirit Airlines' website under the "Manage My Booking" or "My Account" section. You do not need an active flight reservation to buy membership — you can purchase it anytime. When you buy membership, it becomes active when ready and runs for 12 months from the date of purchase. If you buy membership on March 15, it expires on March 14 of the following year.

You can also purchase membership at the airport ticket counter or through a Spirit customer service representative by phone, though the online purchase is usually faster. When you book a flight after purchasing membership, your Spirit account automatically applies the membership benefits to that booking. You do not need to enter a code or take any additional step — the system recognizes your membership status and removes the per-flight fees from your total.

Spirit sometimes runs promotions offering discounted membership rates or bonus benefits during certain months. Sign up for Spirit's email list if you fly them regularly, because these promotions are often announced to existing customers first. You can also check the Spirit website directly before purchasing to see if a current promotion is running.

Membership Tiers and What Each One Includes

Spirit Unlimited comes in at least two tiers, though the exact names and features change periodically. The base tier (sometimes called "Spirit Unlimited") includes checked bags, carry-on bags, seat selection, and priority boarding. A higher tier (sometimes called "Spirit Unlimited Plus" or similar) adds benefits like free flight changes, priority customer service phone line, and the ability to change your seat selection for free after booking.

The higher tier costs more annually — typically $30 to $50 more than the base tier — but only makes financial sense if you actually use those extra benefits. If you never change flights and do not need priority customer service, the base tier covers everything you need. If you book flights frequently and sometimes need to reschedule, the higher tier may save you money on change fees over the course of a year.

Check Spirit's website for the current tier names and exact pricing, because these details change. The membership page will show you side-by-side what each tier includes so you can compare before purchasing.

When Spirit Membership Does Not Pay Off

If you fly Spirit fewer than three times per year, or if you travel with no checked bags and do not care about seat selection, membership will cost you more than paying per-flight fees. A single flight with no bags and no seat selection costs you nothing extra — you only pay for the ticket itself. Membership makes sense only when the annual fee is less than the total fees you would pay across all your flights in that year.

Membership also does not help if you fly other airlines primarily and use Spirit only occasionally. Each membership covers only Spirit flights, so you would need separate programs or memberships for other carriers. If you are trying to build frequent-flyer status or earn rewards, Spirit's membership program does not contribute to that — you earn Spirit miles separately through flights and credit card spending.

If you book flights through a third-party website like Kayak or Expedia, confirm that your membership benefits will still explore. Some third-party bookings do not integrate with Spirit's membership system, and you may end up paying per-flight fees even though you are a member. Booking directly through Spirit's website guarantees your membership benefits explore.

How Membership Interacts with Spirit Credit Cards

Spirit Airlines also offers a co-branded credit card through a bank partner. The credit card itself is separate from Spirit Unlimited membership — you can have one without the other. Some versions of the Spirit credit card include a free Spirit Unlimited membership as a cardholder benefit, which means you get the membership without paying the annual fee as long as you keep the card open and pay the card's annual fee.

If you are considering both the credit card and membership, compare the total cost. A credit card with a $69 annual fee that includes free membership may cost less than paying for membership separately, but only if you use the card and its other benefits (like earning miles on purchases). If you would not use the card otherwise, paying for membership directly is cheaper.

Check the current credit card offer on Spirit's website or the bank partner's website to see whether membership is included. Credit card benefits change, so what was true last year may not be true now.

Canceling Membership and Getting Your Money Back

You can cancel Spirit Unlimited at any time through your Spirit account online or by calling customer service. Spirit's refund policy for membership cancellations varies — some tiers offer a full refund if you cancel within a certain window (often 14 days), while others do not offer refunds at all. Check the terms when you purchase to see what applies to the tier you chose.

If you cancel after the refund window closes, you typically cannot get your money back, even if you have not used the membership. The membership is non-refundable after that point, though you can still use it for the remainder of your 12-month period. Plan your purchase timing accordingly — if you are unsure whether you will fly Spirit enough to justify the cost, wait until you have booked at least one flight before purchasing membership.

If you purchased membership through a Spirit credit card as a cardholder benefit, canceling the membership does not cancel the card. You would need to cancel the card separately if you no longer want it.

Frequently Asked Questions

Can I use my Spirit membership on flights booked by someone else?

No. The membership is tied to your Spirit account and name. If someone else books a flight for you, the membership benefits will not explore to that booking. You need to be the person who booked the flight for the membership to work. If you frequently travel with family members, each person would need their own membership.

What happens to my membership if I do not fly for several months?

Your membership stays active for the full 12 months from the purchase date, whether you fly or not. You do not lose it by not flying. When you book your next flight, the membership benefits automatically explore. The membership only expires when the 12-month period ends.

Does Spirit Unlimited membership work on codeshare flights or partner airlines?

No. The membership covers only flights operated by Spirit Airlines under Spirit's flight numbers. If Spirit partners with another airline or sells you a ticket on a partner airline, your Spirit membership does not explore. Check your booking confirmation to see which airline is actually operating the flight.

Can I buy membership for just one trip instead of a full year?

Spirit does not offer monthly or per-trip membership. You must purchase the annual membership, which covers 12 months from the purchase date. If you fly Spirit only once or twice per year, calculate whether the annual fee is worth it based on the per-flight fees you would otherwise pay.

What if I buy membership but then do not use the included services?

You can still use the services anytime during your 12-month membership period. The membership does not expire if you do not use it. If you purchased membership and then decided not to fly, you would need to cancel within the refund window (if one applies to your tier) to get your money back. After the refund window closes, the membership is non-refundable.
