CommutAir passengers are allowed one piece of carry-on baggage and one personal item such as a briefcase, camera bag, or small backpack. Cabin baggage may not exceed 114 centimeters in width, length, and height. There is no maximum weight limit for carry-on baggage. Checked-in baggage may not exceed 23 kg and may not be larger than 157 centimeters (length + width + height).

Young children traveling without a parent or legal guardian are considered unaccompanied minors. For the safety of minors traveling alone, juvenile escort service is available. The service is mandatory for unaccompanied children between the ages of 5 and 15. Children 16 years of age and older are not required to travel unaccompanied. Children under five years of age are not allowed to travel.

Children under two years of age traveling with a parent or with a customer 15 years or older in the United States, Puerto Rico, and the U.S. Virgin Islands may travel on an adult's lap at no charge. If two or more children under two travel with the same adult, only one of the children may travel as a lap child. All additional children must have tickets for their seats. Children under the age of two traveling worldwide (including Canada, Guam, and Mexico) without a seat must have a ticket purchased and are subject to infant fares and taxes.

Dogs, cats, and pet birds (birds are allowed on domestic flights only) can be taken on board for an additional fee. Pets must be placed in a portable box, which in turn is placed under the front seat. A pet counts as one piece of CommutAir carry-on baggage.
