How fast is Carry-On-Only Travel growing?

Carry-on-only travel refers to the practice of traveling with only the baggage permitted in the airplane cabin, avoiding checked luggage. This approach saves time at bag drop and baggage claim, helps avoid checked baggage fees, and reduces the risk of lost or damaged luggage. It's often associated with minimalist packing, focusing on versatile, lightweight items and sometimes incorporating laundry. While popular for short trips, many travelers apply this method to longer journeys through careful planning. In Saudi Arabia, airlines like Saudia typically allow one carry-on item with specific weight and dimension limits, and travelers must adhere to strict luggage rules, including restrictions on certain items and guidelines for liquids.
