The maximum Sun Country Airlines carry-on size is 24 x 16 x 11 inches, which works out to 61 x 41 x 28 cm. These measurements include wheels, handles, and any external pockets.

Sun Country Airlines carry-on weight limit
Sun Country Airlines limits carry-on bags to 16 kg (35 lb). Most domestic check-in counters do not weigh carry-ons, but gate agents can pull bags that look heavy. If your bag is over the limit, expect to be asked to check it, sometimes at a higher gate-check fee.

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, but Sun Country's online starting price of roughly $25 is often cheaper than Allegiant's dynamic pricing at the gate. 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.
