To find the surface area of the suitcase, we need to calculate the area of each side and then add them up.
The suitcase has 2 sides that are 9.5 inches long and 22.5 inches high, so each of these sides has an area of 9.5 inches * 22.5 inches = <<9.5*22.5=213.75>>213.75 square inches.
The suitcase has 2 sides that are 16 inches wide and 22.5 inches high, so each of these sides has an area of 16 inches * 22.5 inches = <<16*22.5=360>>360 square inches.
The suitcase has 2 sides that are 9.5 inches long and 16 inches wide, so each of these sides has an area of 9.5 inches * 16 inches = <<9.5*16=152>>152 square inches.
Adding up all the areas, the surface area of the suitcase is 2 * 213.75 square inches + 2 * 360 square inches + 2 * 152 square inches = 427.5 square inches + 720 square inches + 304 square inches = <<427.5+720+304=1451.5>>1451.5 square inches.
Therefore, the surface area of the carry-on suitcase is 1451.5 square inches.
