First of all, we need to understand the airline's regulations on the size of the carry-on suitcase. In general, suitcases of 20 inches and under can be carried on board, while suitcases over this size need to be checked in. Therefore, from the point of view of portability, the 20-inch cabin suitcase is undoubtedly the first choice. It's small and lightweight, making it ideal for short trips or business trips, allowing you to board your flight without waiting in line at the airport.
However, the 24-inch cabin suitcase also has its own unique advantages. While it may need to be checked in, its larger capacity means you can carry more items. This is great for long journeys or vacations, so you don't have to worry about running out of space in your luggage during your trip. In addition, some airlines don't charge a lot for checked baggage and may even include it in the ticket**, so you don't have to worry too much about the extra cost of choosing a 24-inch carry-on suitcase.
It mainly depends on your travel needs and personal preferences. If you are a frequent traveler or business trip, and are looking for convenience, then the 20-inch cabin suitcase is undoubtedly the best choice. And if you love to travel long distances or vacations and need to carry more items, then the 24-inch cabin suitcase will provide you with greater convenience.
Of course, in addition to size, there are other factors to consider when choosing a cabin suitcase, such as material, design, brand, etc. A high-quality cabin suitcase should be lightweight, durable, and scratch-resistant, while being well-designed and easy to use. When shopping, you may want to do a little more homework and compare different brands and models of cabin suitcases to find the one that suits you best.
In conclusion, the choice of carry-on suitcase is not set in stone, but needs to be weighed according to individual needs and actual circumstances. Whether you choose a 20-inch or 24-inch cabin suitcase, as long as it can meet your travel needs and bring you convenience, then it is the best choice. Hopefully, this article can provide you with some reference and help when choosing a carry-on suitcase.
