Questions

Questions about the COOWOZ carry-on backpack

Is your COOWOZ 45 liter backpack carry-on size?

By its measurements, 18.5 x 12.6 x 8.7 inches, it is within the 22 x 14 x 9 carry-on size that American, United, Delta, Alaska and JetBlue print. It is too deep to count as a personal item.

Can you check your COOWOZ carry-on backpack at the gate?

If the bin is full an airline may take it at the gate. Take out any power bank first: the FAA says spare lithium batteries must stay with you in the cabin.

This is general information about bags. Airlines set and change their own size limits, so check yours before you fly. For a child, keep a loaded backpack light and worn on both straps, and pack food that must stay cold with an ice pack.
