No, a 28-inch luggage is not necessarily too big for checked baggage, but it depends on its full dimensions and the airline's specific policies. While 28 inches typically refers to the height of the suitcase, airlines evaluate luggage size based on its total linear inches (length + width + height).
Understanding Checked Luggage Dimensions
Generally, for standard checked baggage, a luggage piece must not exceed 62 linear inches. This is a common guideline across many airlines. A 28-inch bag, when its other dimensions are accounted for, can often fall within this limit.
How to Calculate Linear Inches
To determine if your bag complies with airline size restrictions, measure its length, width, and height, then add those three measurements together.
- Formula: Length (L) + Width (W) + Height (H) = Total Linear Inches
For example, a common 28-inch suitcase might have approximate dimensions of:
- Height (H): 28 inches
- Width (W): 18 inches
- Depth (D): 12 inches
Calculation: 28" + 18" + 12" = 58 linear inches.
In this common scenario, a 28-inch bag would be within the typical 62-linear-inch allowance, making it acceptable for checked baggage.
Typical Dimensions and Airline Policies
While 62 linear inches is a widely accepted maximum, it's crucial to remember that airline policies can vary. Always verify the specific rules with your chosen carrier before you fly.
| Luggage Dimension Type | Common Standard | Note |
|---|---|---|
| Maximum Linear Inches | 62 inches | Sum of Length + Width + Height |
| Common 28-inch Luggage | Approx. 28" H x 18" W x 12" D | ~58 linear inches, often acceptable |
| Overweight Fee Trigger | Varies (e.g., 50 lbs / 23 kg) | Separate from size, but often applies to larger bags |
Factors Beyond Size
Even if your 28-inch bag meets the linear inch requirement, other factors can determine its eligibility and cost as checked luggage.
Weight Restrictions
Most airlines impose a weight limit for standard checked bags, typically around 50 pounds (23 kilograms). Bags exceeding this limit are subject to overweight fees, which can be substantial. Larger bags, like a 28-inch suitcase, are more prone to exceeding weight limits simply due to their capacity.
Airline-Specific Policies
Baggage policies can differ significantly based on:
- The specific airline you are flying with.
- Your destination or route.
- Your ticket class (e.g., economy, business, first).
- Your loyalty program status.
Always consult your airline's official website or customer service for the most accurate and up-to-date information regarding their baggage allowances before your trip. This will help you avoid unexpected fees or last-minute complications at the airport.
