How Big Is Underseat Luggage?

Each airline has its own size restrictions for underseat luggage based on their planes’ dimensions. The published size limits for underseat luggage or personal items is around 15 x 13 x 8, but you should always check with your airline before you pack. Our guide to Traveling with Underseat Luggage & Personal Item Bags has a chart of personal item size limits for the most common domestic carriers.

Is Underseat Luggage a Personal item?

Underseat luggage is considered a personal item, as long as it fits beneath the seat in front of you. Other bags that may be considered personal items include purses, laptop bags and backpacks, camera bags, totes, and diaper bags. Airlines have strict rules concerning the size of under-seat luggage: if your personal item exceeds an airline’s under-seat dimensions, it will have to be checked or placed in an overhead bin, which may incur fees.

How Do I Pack Underseat Luggage?

If you are using your underseat bag as your main suitcase, packing cubes and other organizing essentials can help you make the most of the space you have. Knowing what you can and cannot pack in your Underseat luggage is important. Airlines have strict rules about what you can bring on a plane so always check their website before packing to avoid hassle at the airport.In general, underseat luggage should adhere to the same rules as carry-on luggage. Adhere to the TSA 3-1-1 Liquid rule, don’t pack sharp items or anything that could be used as a weapon, and always keep any prescription medicine or e-cigarettes you are traveling with in your carry-on bags.Related: What to bring and not bring in a carry-on or personal item. If you’re traveling with both a personal item, like an underseat bag, and a carry-on suitcase, use the carry-on for everything you won’t need until you’ve reached your destination. Your personal item should make it easy to access your in-flight needs, such as ID and money, headphones, snacks, reading material or entertainment, and a jacket or wrap.
