What size should your carry-on luggage be? On domestic flights within the United States, a carry-on bag that's smaller than 22 x 14 x 9 inches (45 linear inches), including handles and wheels will meet the size restrictions of all major airlines, such as United Airlines and Alaska Airlines.
Usually, many airlines won't check every carry-on but will instead go for ones that look oversized. If your luggage does not fit in the sizer, you might have to pay a checked bag fee along with the gate checking fee and have your bag transferred to the airplane's cargo.
If your checked bag is over 62 linear inches (157 cm), it will be marked as oversized. This is a rule set by airline regulators to protect baggage handlers from any potential injuries.
Airlines publish the maximum dimensions allowed for carry-on bags. For example, American Airlines states that a carry-on bag's dimensions cannot exceed 22 by 14 by 9 inches, including handles and wheels. The carry-on must also fit into the sizer at the airport; if it doesn't, you'll be required to check it.
30-inch luggage is one of the largest options, so it's going to weigh more than a 26-inch one or your carry-on. Most airlines have a maximum weight limit of 50 pounds per checked bag. This limit does not take into account size, so 30-inch luggage needs to meet the same requirements as 26-inch luggage.
Overweight items 71-100 pounds will cost $125. Oversized items in excess of 62 inches but not more than 80 inches will be accepted for a charge of $125 per item. Only one $125 charge applies if the piece is both oversized and overweight, regardless of the weight as long as it does not exceed 100 lbs.
29 inches is too large for domestic carry on, let alone international. Most international carry limits are around 21 inches maximum, which includes the wheels. If you are looking for a check through bag then 27 inches is the “normal” size though that varies by airlines.
Large (27 to 30 inches)Ideal for long trips or carrying the belongings of more than one traveller, these also have to be checked. New airline regulations limit individual luggage size to 30? in length and 62? total (height + width + depth). The fines for not abiding to the size rule are hefty.
The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27 x 21 x 14. Airline carriers will allow overweight, oversize or additional baggage for additional fees.
The answer depends on the airline. Some airlines may let it slide and not charge you for a large bag, while others may not be so lenient. And if the airline does decide to charge for the oversized item, it could end up costing you a pretty penny.
There's a better chance of a soft-sided bag being able to be pushed into an overhead compartment or fit under the bed of a hotel room. And, when it comes to packing, soft-sided luggage offers the luxury of expansion.
In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container (3), all containers must be placed inside one clear quart-size plastic bag (1) and each passenger is only allowed one plastic bag (1).
Medium suitcase – 24 inch, Large suitcase – 27 inch, Extra large suitcase – 32 inch, Please note that a hard case will generally be smaller in capacity to a soft sided case of the same size due to it not being able to expand or bulge out with packing.
