Sun Country Carry On Size (2026)

Sun Country’s published overhead (carry-on) limit is 24 × 16 × 11 inches (height × width × depth; about 61 × 41 × 28 cm), 35 lb, and it is a paid add-on on the base fare, not free by default. Every reservation still includes one free underseat personal item at 17 × 13 × 9 in. Overhead must fit the sizer at the ticket counter or gate. The exact overhead price varies (Explore Bag Prices): cheapest online at booking, higher at the ticket counter, most expensive at the gate (a $10 Gate Handling Fee on top of “At airport” bag fees). Do not treat any single nationwide dollar as fixed.

Based on Sun Country’s bags and optional services page and its Stories guide on how to book (bag sizes). The size and weight limits on this page are fixed; fee timing and overweight and oversize fees are on our Sun Country baggage fees page. Overhead prices for a specific city pair need a live flight search in Explore Bag Prices; check before you travel.

Sizer enforcement is real: a bag that exceeds 24 × 16 × 11 or fails the physical sizer is not treated as a free overhead item. Sun Country’s published overhead size (24×16×11) is larger than the 22×14×9 at Avelo and Breeze, but “fits overhead” still does not mean “free on the base fare.”

• Free with ticket: one underseat personal item (17 × 13 × 9 in) on all reservations; mobility and medical devices per the official bags page (not counted as overhead).
• Paid: overhead bag, priced in Explore Bag Prices or when you book; the price rises from booking to the ticket counter to the gate (plus a $10 Gate Handling Fee at the gate). There is no fixed nationwide overhead price.
• Checked bags are also paid add-ons; see Sun Country baggage fees for the full tables.
• Active U.S. Military (with ID): 1 overhead bag and 2 checked bags free (up to 100 lb each); companions and veterans pay standard rates.
• Seats (Best, Exit Row, Standard) are paid seating products, not a bag allowance.
• Optional Bundle Deals (seats, bags and extras) may appear when you book; check the current contents and prices there. There is no named “Basic Economy” bag fare on the bags page; the model is à la carte (only the underseat item is included).

1. Strict sizer at the ticket counter or gate. A pre-purchased overhead bag that doesn’t fit is checked, and additional charges can apply.
2. Bin full. Remaining overhead bags may be tagged as checked; only travelers who selected the overhead option use the bins.
3. Gate purchase costs more: the “At airport” bag fee plus a $10 Gate Handling Fee.
4. Soft or expandable bags marketed as “carry-on” can still fail 24 × 16 × 11 when packed; the outside packed size is what matters.
5. The free underseat item and the paid overhead bag are not the same. Base fare: 17 × 13 × 9 personal item only; the full 24 × 16 × 11, 35 lb overhead bag is always a paid add-on unless Military free overhead or a current Bundle Deal includes it (check when you book).
6. Prices vary by flight, so do not budget from one fixed nationwide overhead price.

• Pack to the free underseat 17 × 13 × 9 in if traveling light.
• If you need overhead space, buy online at booking (the lowest price); avoid the ticket counter and especially the gate.
• Measure the packed bag including wheels and handles; stay under 24 × 16 × 11 in and 35 lb.
• Military ID: claim the free overhead when eligible.
• Optional Bundle Deals: check them when you book if you are packing more than a personal item.

Look for hard or soft carry-ons marketed at or under Sun Country’s published 24 × 16 × 11 inches, and confirm with a tape measure before you fly. Soft under-seat bags at or under 17 × 13 × 9 cover the free personal-item slot. Product listings often reorder depth, width and height; match Sun Country’s published height × width × depth, not another airline’s order.
