Alaska

Alaska allows bags of 24" x 17" x 10" and doesn't have a weight restriction, which means you can get away with a heavier hard-sided suitcase. The N.Y. Cargo Vacationer Hardsided 24" Spinner Luggage has a durable polycarbonate exterior and wheels that rotate a full 360-degrees to help you maneuver around the airport. The handle retracts with a push of the button to stash it away in the overhead.
American

Like many domestic airlines, American will only accept carry-ons of 22" x 14" x 9". Unlike most, however, they also have a weight restriction (40 lbs.). Don't waste pounds on the suitcase itself — get the IT Luggage World's Lightest Second Generation 22" Carry-On Upright, which weighs about 3 lbs. Measuring 22" x 14" x 8.7", it will maximize your allowable space. And best of all, it's super light on your wallet.
Delta, United, and Allegiant

These three airlines will take bags of up to 22" x 14" x 9" with no weight restrictions in the cabin. This Travelpro Crew Rollaboard meets the dimensions precisely, plus it has a lifetime warranty. Bought too much at your destination and need to check a bag on the way home? This suitcase expands to accommodate extra shopping. We like that the telescoping handle can be set to use at different heights (great for shorter or taller travelers).
