Airline Travel Guidelines for Protective Cases
When traveling with equipment, understanding airline baggage size and weight limits is essential to avoid delays, damage, or unexpected fees. Airlines calculate baggage size using linear dimensions (length + width + height), and restrictions can vary depending on the carrier, route, and ticket class. This guide outlines general airline standards to help you select the right travel case for carry-on and checked luggage.
The size limitation of your checked luggage and carry on is calculated by adding the total outside dimensions of each bag (*linear dimensions), that is, length + width + height. It is important that you check with your airline for their specific policy, to avoid additional baggage fees.
Carry-On Size & Weight Limits for Travel Cases
In general, most airlines have adopted a maximum carry-on size of 45 linear inches, determined by adding up the length, width and depth of a bag (typically 22 x 14 x 9 inches). These dimensions are determined by taking the longest measurement, including handles and wheels.
While most airlines do not weigh carry on items, most have a 40-pound limit per piece. On domestic flights, the typical allowance is one (1) carry on bag, and one (1) personal item such as a purse, briefcase, laptop bag or camera bag. Almost every airline requires that personal item to be smaller that your carry-on. For example, you may not have two 22 x 14 x 9" carry on bags with you and count one as a personal item. In addition, some airlines set size and weight limits for personal items, so it's important to check with your airline first for their specific policy.
Checked Baggage Guidelines for Equipment Cases
For checked luggage, most airlines allow a maximize size of 62", although some allow up to 72". Most airlines allow a maximum weight per checked bag of 50-pounds. and some allow up to 70 lbs. at extra cost.
Baggage limits are determined by individual air carriers, and can vary widely. These standards can change at any moment, so it's always advisable to check with the airlines prior to travel.
Most airlines employ different rules for domestic flights and international travel, with a more generous allotment for flights abroad.
If in doubt, check with your air carrier.
Airline Policy Variations & Travel Considerations for Transit Cases
Baggage policies are set by individual air carriers and can change without notice. Factors that influence baggage allowances include:
-
Domestic vs. international routes
-
Ticket class (economy vs. business/first class)
-
Frequent flyer status
-
Aircraft type and overhead storage capacity
To avoid issues at the airport, it is always recommended to verify baggage requirements directly with your airline before traveling.
Choosing the Right Transit Case for Air Travel
Selecting the right protective case ensures your equipment stays within airline limits while remaining fully protected during transit.
-
Carry-on cases are ideal for sensitive or high-value equipment that should remain with you during travel
-
Checked cases are better suited for larger, heavier gear that exceeds carry-on size limits
-
Lightweight, durable materials help maximize usable space while staying within airline weight restrictions
-
Custom foam inserts keep equipment secure and prevent movement during handling and turbulence
Shipping & Travel Case Design Considerations
Air travel introduces unique handling conditions, including frequent transfers, stacking, and vibration. Proper case design helps protect your equipment from damage throughout the journey.
