Go onto the website for the airline you are flying on to see what the measurements are that they allow. Be sure to measure from the floor to top of your bag including the wheels because wheels count in the measurement. What airline are you flying? If its Southwest, they don't charge for your first 2 bags checked. Most airlines allow one carryon (suitcase, garment bag, rollerbag) & one personal item (purse, diaperbag, briefcase).
