Knowing the maximum dimensions for airline carry-ons and personal items is necessary to avoid checked baggage fees. While many airlines have overlapping maximum dimensions, there can be some variations in baggage policies.

What Is The Standard Carry-On Luggage Size?

Most airlines permit carry-on luggage as large as 22 (length) x 14 (width) x 9 (height) inches. However, the piece may be gate-checked (usually at no extra cost) if it doesn’t fit in the overhead bin or underneath the seat due to overcrowding or flying on a small plane.
