As of 2015, US Airways allows a carry-on bag and personal item in the cabin. No baggage allowance exists for domestic flights or those flying to the Caribbean, Mexico and Central America. Passengers must pay for checked bags on domestic, Caribbean, Mexican and Central American flights.
On flights to Brazil and South America and trans-Pacific flights, the first two checked bags are free. On trans-Atlantic flights, only the first checked bag is free. Passengers can check additional bags after paying a fee for the bag. Overweight and oversized bags garner an additional fee, even when only one bag is checked.
