Luggage Size Guide For Air Travel & Baggage Allowance

Comment Your Feedback

Luggage is a broad term with many varieties in the market, each with a different use case and style. For airline travel, luggage size is mainly divided into personal, cabin, and check-in bag. 

Different airlines have varying policy regarding baggage allowances; some airlines charge fees, some have certain conditions while other offer free baggage allowance.

In the article below, I have covered luggage size guide and airlines baggage policy along with their site reference for you to check.

Luggage Size Guide

Carry-on Luggage (Cabin Bag)

Cabin luggage is designed to fit under the seat or overhead compartment of an airplane, and they mostly measure around 22″ in height, 14″ in length, and 8″ in width.

They are usually preferred for short trips and have a larger capacity than personal bags but lower than check-in. It also allows one to exit/depart from the airport earlier, as you do not need to wait at the conveyor belt for luggage claim.

Sometimes, the size of the overhead compartment of domestic flight planes is less spacious than that of international flight planes. Double-check the size limit for the overhead compartment of the respective plane. 

Note: if you have softshell luggage, avoid extending its dimensions by overpacking it. 

Checked Luggage

Most airlines measure the linear dimensions of luggage, which are 62 minimum for check-in luggage, and their minimum dimensions are 24″ height x 17″ length x 10.5″ depth. 

Based on the size, check-in luggage is divided into three variations, including small suitcase (24”h x 17 ”l x 10.5”w), medium check-in (27”h x 18.5”l x 14”w), and large suitcase (32”h x 22”l x 14”w).

Each suitcase size is helpful for different use cases and cost-effective, especially if you have a lot of stuff to travel with. Most airlines charge fees for checked luggage, except Southwest Airlines. 

Southwest allows two free checked luggage with a weight limit of up to 50 lbs; linear dimensions must not exceed 62. Conversely, you will be charged up to 125 dollars for an overweight-sized bag.

You can also avoid checked luggage fees if you hold any credit cards from a premium company, have a membership with your respective airline, work as a veteran, or travel in higher classes than the economy.

Personal Item/Bags

Personal bags that are more petite than a carry-on include totes, purses, backpacks, briefcases, and small duffel bags. Almost every airline allows one personal bag and carry-on under the weight limit.

Personal bags are supposed to fit under the seat in front of you on planes and it also gives you hard time by occupying legroom. Each plane is unique and has a different under-seat space. 

The maximum allowed dimension for the personal bag is around 18″ x 14″ x 8″; it can vary significantly from airline to airline. It is essential to check it with your flight airline.

Oversized Luggage Problems

Oversized luggage is a hassle. Maneuvering through busy airports and crowded city streets becomes a workout. You risk missing connections and straining yourself with heavy lifting.

  • Airlines don’t help; they slap extra fees for oversized bags, quickly inflating travel costs.
  • Your suitcase takes a beating during transport. Rough handling increases the chances of damage to the luggage and its contents.
  • Hotels aren’t spacious havens either. Limited storage means your oversized luggage becomes a storage puzzle.
  • Public transportation complicates things further. Buses, trains, and taxis may charge you extra or refuse service due to your bulky baggage.
