Suitcases and travel gear buying guide

Check the airline's size and weight limits before you check the suitcase's looks.

1. Carry-on limits vary by airline, so compare the case's exterior size, including wheels, to your airline's rules.
2. Hard shells resist crushing and rain; soft cases squeeze into tight spaces and often have outer pockets.
3. Four spinner wheels roll easily on smooth floors; two larger wheels cope better with rough ground.
4. Look for a sturdy telescoping handle and a lockable zip.
5. A lighter empty case leaves more room in your weight allowance.

Common mistake: Choosing by capacity alone and then discovering the case is too big for the cabin.
