Sun Country’s base fare includes a seat and a personal item. Nothing else. Carry-on and checked bags are add-ons you buy separately, which is the core of Sun Country baggage rules.
That is confirmed by Sun Country’s own published material. The exact dimensions are a different story, and we will be straight with you about why.
Why Sun Country baggage rules have no size table here
Sun Country’s baggage pages sit behind bot protection that blocks automated reading. Every route we tried returned a security page instead of the policy.
We publish figures only when we have read them off the carrier’s own page. We have not been able to do that here, so we are not publishing numbers.
Plenty of sites will give you a confident table for this airline. We cannot confirm where those figures came from or when they were last checked.
That is the whole point of how we verify. A gap we admit is more useful than a number we guessed.
What we can confirm
The base fare covers a seat and one personal item that fits under the seat in front of you.
Carry-on bags and checked bags are purchased on top of that fare. Sun Country states that it posts size and weight limits online.
This is the standard unbundled model. It works the same way at Frontier and Allegiant, where only the personal item is guaranteed.
How to check Sun Country baggage rules before you fly
Open your booking and look at what the fare actually includes. Unbundled carriers list bags as line items rather than allowances.
Buy any bag you need at booking. On every carrier in this category the price rises at check-in and rises again at the airport.
If you can pack to a personal item, do. That is the fare you actually bought, and it is where the low headline price holds up.
What to expect from an unbundled carrier
Sun Country baggage rules follow a pattern worth understanding in general terms.
The personal item is free and is usually generous enough for a short trip. The carry-on costs money and often costs more than people expect.
Bag prices are typically dynamic, varying by route and by how late you buy. Assume the airport is the most expensive place to make the decision.
The bottom line
Sun Country sells a seat and a personal item. Everything else is an add-on, so price the fare with your bags included before comparing it to anyone else.
We will publish full dimensions here as soon as we can read them from Sun Country directly. Until then this page stays marked unverified rather than filled with borrowed numbers.
Meanwhile, the size checker covers the carriers we have verified, and the general cabin rules apply everywhere.
