FREE Ground Shipping! FREE Monogramming on Leather Luggage Tag! We offer carry on luggage designed for domestic or international flights. Most domestic airlines have a 45 linear size carry on requirement. You need to measure the height, width, and depth and add it together. However, you should check with your individual airline as some have different requirements. Travelers today seem to all want carry on luggage. You don't have to wait around at the crowded baggage carousel and you don't have to worry about the airlines losing your bag. Carry ons come in all colors, models, and prices. You can get them with two wheels or four wheels. The four wheel models can be rolled down the aisle conveniently. You can usually take two pieces on board with you. One carry on that fits in the overhead (45 linear inches) and one personal bag that fits underneath the seat in front of you. Check with your airlines! QUESTIONS?
