The answer to this question will depend on different factors, including the airline's carry-on baggage policies, the dimensions of the luggage, and your personal preferences as a traveler.
In general, most airlines have specific size and weight restrictions for carry-on luggage that passengers must adhere to. While these restrictions can vary depending on the airline, the typical dimensions for a carry-on bag are around 22 inches long, 14 inches wide, and 9 inches high. However, some airlines may allow slightly larger bags or may have different size limits depending on the class of service or frequent flyer status.
If your luggage measures 24 inches in height, this could be considered oversized for some airlines' carry-on policies. It's important to check your airline's specific size and weight limitations to ensure that your bag is compliant. You can usually find this information on the airline's website or by contacting their customer service department.
If your luggage is just slightly larger than the carry-on size limit, you may be able to fit it into the overhead compartments on most planes. However, keep in mind that it may be difficult to do so if the plane is fully booked, or if you have other items with you, such as a personal item or a coat.
Lastly, it's important to keep in mind your own travel preferences when deciding whether a 24-inch luggage can be a carry-on for you. If you prefer to avoid checking bags altogether, you may want to opt for a smaller carry-on size. On the other hand, if you have items that you absolutely need to bring with you on the plane, a slightly oversized bag may be necessary. Ultimately, the decision is up to you, but it's important to be aware of airline policies and your own needs as a traveler.
