This page goes deeper on one part of the policy. The full record is at Spirit Airlines Baggage Rules.
Spirit Airlines stopped flying on May 2, 2026, and there is no current Spirit carry-on size to check. Anyone searching for a Spirit carry-on size chart, sizer dimensions or a gate fee is looking for a policy that no longer exists.
Plenty of pages, forum threads and old screenshots still describe Spirit carry-on size limits from before the shutdown. Treat all of them as history, not a live policy. An airline that has ceased operations sets no rules and charges no gate fees.
Why this page still exists
Search traffic for Spirit carry-on size did not stop the day Spirit did. People had trips booked or had simply memorized the old sizer dimensions.
This page exists to redirect that search to something useful, not to leave a dead end.
Where to check carry-on size now
If you are flying a low-cost US carrier this year, check the airline you actually booked. Spirit’s model, a strict bag sizer plus a separate carry-on fee, is still alive at three other carriers.
- Frontier Airlines runs its own sizer and its own carry-on rules by fare. They are not the same as Spirit’s old numbers.
- Allegiant Air charges separately for a carry-on bag on most fares, with its own box size.
- Avelo Airlines also prices carry-on bags apart from the base fare on many routes.
Run whichever airline you booked through our bag size checker. Guessing from a defunct airline’s chart is how a bag ends up checked at the gate for a fee.
It also helps to read up on what basic economy fares actually include before you pack. The cheapest fare class is usually where a carry-on gets excluded first.
If you have an unused Spirit ticket
Refunds for flights an airline cancels, including a shutdown, are covered by federal rule, not airline goodwill. The Department of Transportation’s refunds page explains when a passenger is owed cash back rather than a voucher.
It also covers how to escalate a claim that stalls.
If Spirit will not process a refund directly, most banks and card networks accept a chargeback for services paid for and never delivered. Keep the original booking confirmation and any cancellation notice as evidence. File the dispute with your card issuer rather than waiting on the airline.
A travel credit card that already covers baggage fees on other airlines can soften the cost of rebooking elsewhere.
What carry-on size actually means going forward
The habit worth keeping from the Spirit era is checking the sizer, not memorizing a number. Every ultra low cost carrier sets its own box, its own personal item rule and its own gate fee.
Those figures change over time even at carriers still flying today.
Read the current carrier’s own carry-on page before a trip. Do not trust a chart you remember from a Spirit flight years back.
Our carry-on size chart tracks the airlines still operating. It is rebuilt from each carrier’s own published rules, not from memory.
The bottom line
There is no Spirit carry-on size to look up because Spirit Airlines is not flying. Check Frontier, Allegiant or Avelo instead if you booked one of them.
Chase a refund or chargeback through the DOT process if you are still owed money on a Spirit ticket. Treat any Spirit carry-on numbers you find elsewhere online as leftovers from a service that ended on May 2, 2026.
Common questions
Does Spirit Airlines still have a carry-on size limit?
No. Spirit Airlines ceased operations on May 2, 2026 and no longer flies, weighs bags or charges gate fees.
What happened to my Spirit Airlines flight credit or voucher?
Contact your card issuer about a chargeback for services paid for and not delivered, and see the Department of Transportation refunds page for what you are owed.
Which airline is most like the old Spirit Airlines now?
Frontier Airlines, Allegiant Air and Avelo Airlines all use a similar low fare plus separate bag fee model.
Are the Spirit carry-on dimensions I found online still accurate?
No. Those figures describe a service that no longer runs and should not be used to pack for any current flight.
Can I get a refund for an unused Spirit Airlines ticket?
The Department of Transportation refunds page explains when a refund is owed for a flight the airline itself canceled.
Why does carryonsizes.com still have a Spirit Airlines page?
People still search for it, so this page redirects them to airlines that are actually flying today.
