American Airlines's carry-on baggage allowance

On most flights, AA lets you take one small personal item (like a purse or small handbag) on board with you, plus a carry-on with dimensions of 22 x 14 x 9 inches—so you'll have plenty of space for your book, laptop, or other handy items in your carry-on baggage. American Airlines's permitted carry-on size may vary and additional charges may apply, so be sure to confirm the specific details before heading to the airport.

American Airlines's checked baggage allowance

Most of the time, the maximum weight for AA check-in baggage is usually 50 lb per bag, although this depends on your destination. If you're travelling to Australia or New Zealand on American Airlines, your baggage allowance may go up to 70 lb, for instance—so make sure to double-check the terms. When you do need to exceed the check-in baggage limit, you can usually purchase extra baggage allowance for a fee.
