Why Knowing Luggage Size Restrictions is Important?
Different airlines have different size restrictions due to plane designs. Airplanes are just like vehicles; hence they come in different sizes and shapes. Bigger planes tend to offer more luggage size options and limits/baggage allowance, while the converse is also true. Knowing these dimensions is important since it helps to eliminate the hassle and uncertainty of figuring out the maximum allowed luggage size. The availability of numerous airlines with different under-seat luggage size restrictions helps cater to different passenger needs. However, you should be aware that size restrictions might change, and it’s therefore important to keep yourself up to date.
