Carry-on Baggage Size Restrictions
When oversized bags do not fit in the overhead bins, delays occur. Fees will be applied to the oversized bag if it has to be checked at the gate. To avoid delays as well as fees, follow these size requirements:
Baggage may not exceed 45 linear inches (or 115 cm) in combined length, width, and height.
Baggage must fit easily in the Carry-on Baggage Check, which is located near the check-in counters and at the gate and is approximately 22" x 14" x 9" (or 56 x 36 x 23 cm).
