Most U.S. airlines permit:
- One carry-on bag

Examples of personal items include:

- Small backpack
- Purse
- Briefcase
- Camera bag

Typical carry-on dimensions are approximately:
- 22 x 14 x 9 inches (56 x 36 x 23 cm)

Understanding Personal Item Allowances
A personal item is separate from your carry-on bag.

Checked Baggage Allowances Explained
Checked baggage is luggage placed in the aircraft cargo hold.
Standard checked luggage usually allows:

Linear inches equal:
Length + Width + Height
For example:

Exceeding these limits often results in additional baggage fees.
