If you plan to fly over the holiday season, using a carry-on suitcase can save a lot of time and worry. You won’t have to wait at the baggage carousel, you’ll minimize the chance of a stolen or lost bag, and you’ll have everything you need in the overhead bin.

In a recent survey, Consumer Reports subscribers agreed. Of the 39,000 subscribers who said they flew in the past year, more than half say they use a carry-on bag on some or all of their trips. Almost three-quarters told us that they do so to save time at the airport.

Of course, all the benefits of carry-on luggage will be lost if the bag is too big and the airline won’t let you take it on. It also could be a problem if the bag's allowed on but is packed so tightly you can’t cram it into the overhead bin.

Our advice: Make traveling a little easier. Find a bag that you can comfortably take on the plane with you.

More on Luggage

Here are four steps to take to buy the right carry-on luggage.

Measure It
The maximum allowable dimensions for domestic flights on the big three airlines—AmericanDelta, and United—are 22 inches high, 9 inches deep, and 14 inches wide. This includes wheels, retracted handles, and compartment protrusions. Most importantly: Measure it yourself with a tape measure. You can’t always rely on the product dimensions found on the bags’ hangtags or on a seller’s website to determine whether a piece of luggage is carry-on-compliant. 

Spin It
Most luggage sold in the United States comes with wheels. In our survey of the more than 14,000 readers who had replaced their luggage for reasons other than loss or damage, more than half of respondents told us that one reason they replaced their existing luggage was that they wanted a case that was “easier to wheel.” For carry-on, easier-to-wheel usually means four wheels instead of just two. A four-wheeler, also called a spinner because the wheels turn 360 degrees, is easier to navigate in tight spaces—like in the aisle of an aircraft. It also beats the two-wheeler in ergonomics because you can push it, pull it, wheel it at your side, and turn it in any direction.

Look Inside
Not all interiors are created equal, even with the same exterior dimensions. And it can be hard to know just how much space you actually have since many manufacturers don’t disclose the interior volume. But certain features maximize interior packing space. These include squared (not curved) corners, outer compartments that are integrated (not protruding), and handles mounted on the exterior (not inside, where it occupies valuable real estate).

Weigh It
Most of the weight you lug around should be the weight of your belongings, not the bag. Thirty-one percent of recent luggage purchasers in our survey who replaced their luggage wanted something lighter. Experts recommend that a wheeled bag weigh no more than 7.5 pounds.
