At-A-Glance Guide: Airline Baggage Size Restrictions

While to some it may seem arbitrary, the overall size and dimension of an airplane passenger's luggage is restricted for several important reasons.

The pilot and crew need to know the overall weight of the aircraft -- including passengers and luggage -- for accurate fuel calculations and efficiency. If the plane is too heavy because of extra luggage, it cannot take off safely, or smoothly in a way that allows the wings to create lift. Proper weight and distribution alleviates strain on the body of the airplane and also helps it land without being bumpy (most of the time). Each piece of baggage is limited in weight so that handlers are able to load and unload luggage.

Here is a list of the top airlines we book regularly and the at-a-glance guide to the size and weight restrictions for carry-on and checked bags. If you need to purchase new suitcase, we've also included an airline-specific Amazon link for your convenience (non-affiliate).

(Please note that allowances may increase depending on the ticket class of service you purchase.)
