Sun Country is a hybrid low-cost carrier, which means the cheap fare you found buys you a seat and one personal item, and nothing else. That personal item has to slide under the seat in front of you — max 17 x 13 x 9 inches — and that’s the entire free allowance. No overhead carry-on, no checked bag. If it doesn’t fit under the seat, you’re paying.
And this holds on every route the airline flies: Sun Country is a leisure carrier with no long-haul intercontinental network, so there’s no “free bag to Mexico/the Caribbean” carve-out the way full-service airlines bundle a bag on long-haul fares. A cheap fare to Cancún, Costa Rica or Canada strips a bag exactly like a domestic hop to Las Vegas does. Both the overhead carry-on and the first checked bag are à la carte add-ons — roughly $30–$50 at booking, climbing toward $55 plus a $10 gate-handling fee if you wait. Sun Country sells Bundle fare tiers that fold bags/seats/priority together, but the headline price you clicked is almost always the bare “no bundle” fare.

What you actually get on a cheap fare
On a cheap Sun Country deal fare you get a seat and a single under-seat personal item — that’s it. No overhead carry-on, no checked bag. If you only travel with a backpack that fits the 17 x 13 x 9 in box, you fly bag-free for the headline price. Everyone else is buying up.
Budget realistically: a carry-on or a first checked bag added at booking runs about $30–$50 each way, so a round trip with one bag adds roughly $60–$100 on top of the fare. The single biggest money rule with Sun Country: add bags online when you book, never at the gate — at the airport you pay up to $55 plus a $10 gate-handling fee per bag, and that stacks each direction.
Oversize, sports & special items
Checked bags max out at 50 lb and 62 linear inches; go over and you pay surcharges on top of the base bag fee — +$20 for 51–60 lb, +$60 for 61–100 lb, and +$100 for oversize over 62 inches. Sun Country won’t accept bags over 100 lb at all. Most sporting equipment (skis, golf clubs, bikes) is handled as a special-handling item at a flat fee around $100, and counts toward your bag allowance.
Two perks worth knowing: active U.S. military with a valid Common Access Card get three free bags, and Sun Country Visa cardholders typically get 50% off the first checked bag when bought online pre-flight. Fees and exact ranges shift by route, date and booking channel.
