Travel Backpack vs Carry-On Suitcase

A rolling carry-on is easy on smooth floors, while a travel backpack goes anywhere. The wheels and handle also take up space that a backpack uses for packing.

Choose Travel backpack if

  • You travel through cities with stairs and transit
  • You fly budget carriers with strict sizers
  • You want the most packing volume

Choose Carry-on suitcase if

  • You have back or shoulder issues
  • Most trips are airport to hotel
  • You carry heavier loads

The bottom line

For true one-bag travel a clamshell backpack is usually the better choice because it maximizes volume and goes anywhere. A rolling carry-on wins when carrying weight on your back is not an option.
