Sun Country Airlines carry-on dimensions and bag size

The maximum Sun Country Airlines carry-on size is 24 x 16 x 11 inches, which works out to 61 x 40.6 x 27.9 cm. These measurements include wheels, handles, and any external pockets, so a bag marketed as "22 inch" can go over if its wheels push the total past 24 inches. Always measure your bag packed, not empty.

Sun Country Airlines limits carry-on bags to 16 kg (35 lb).

Does Sun Country Airlines charge for carry-on bags?

Yes. Sun Country Airlines charges for carry-on bags on most fares, with a price that varies by flight and is lowest when added at booking.

Sun Country Airlines overhead bin size by aircraft

Sun Country operates an all-Boeing 737 fleet out of its Minneapolis-St. Paul hub. Overhead space is typical for a 737, but because most travelers pay for a carry-on, paid bags compete for bins on nearly every flight.

What counts as a personal item on Sun Country Airlines

Allowed

  • Backpack within 17 by 13 by 9 inches
  • Purse, laptop bag, or small tote that slides under the seat
  • FAA-approved medical equipment at no charge
  • Diaper bag when traveling with an infant

Counts as a second carry-on

  • Roller bag meant for the overhead bin
  • Oversized duffel that will not fit under the seat

Common Sun Country Airlines carry-on mistakes

  • Showing up at the gate with a carry-on without pre-paying. Airport bag prices are the highest, and a $10 gate handling fee is added at the gate.
  • Confusing the 17 by 13 by 9 inch personal item limit with larger airline norms and packing too deep a tote.

What happens if your bag does not fit on Sun Country Airlines

If you did not pre-pay and bring a second bag, expect the gate agent to charge the airport bag price plus a $10 gate handling fee and tag it to the hold. If you pre-paid and bins are full by the time you board, gate-check is free.

Sun Country Airlines vs Allegiant Air carry-on

Sun Country and Allegiant are both low-cost, a la carte carriers, but the bag rules cash out differently. Sun Country allows a comparatively generous 24 by 16 by 11 inch carry-on up to 35 pounds, which is larger than Allegiant's 22 by 16 by 10 inch cap. Both charge for overhead bags with dynamic pricing; on Sun Country the bag is cheapest when added at booking and most expensive at the airport. Sun Country flies a 737 fleet while Allegiant leans on A320-family jets, and Sun Country's personal item at 17 by 13 by 9 inches is a different shape than Allegiant's 18 by 14 by 8 inch allowance.

Checked bags are dynamically priced by flight and not published as a flat figure (the official bags page defers to a flight-search price tool), so no flat first or second bag fee is listed here. Bags are cheapest when added at booking, more expensive afterwards, and most expensive at the airport; a $10 Gate Handling Fee applies on top of the airport price for bags bought at the gate. Effective September 3, 2025, overweight surcharges are tiered: 51-60 lb +$25, 61-70 lb +$50, 71-80 lb +$75, 81-90 lb +$100, 91-99 lb +$125 (listed here instead of as single overweight fees because the tiers do not fit one 51-70 or 71-100 lb band). 100+ lb not accepted on any Sun Country flight; 70+ lb not accepted on flights to/from Canada, Jamaica, Puerto Rico. Oversized bags (63+ linear inches): $100. Special sporting equipment: $100. Max bag 50 lb and 62 linear inches; 80+ linear inches not accepted.
