As of January 1, 2008, travelers may not pack spare lithium batteries of any kind in checked baggage. Passengers wishing to carry spare lithium batteries for devices such as laptops, cell phones and cameras are now required to pack them in their carry-on baggage with the terminals covered or insulated. Travelers may check bags that contain batteries, as long as they are installed in electronic devices.
Please see the Safe Travel website for tips on traveling with spare batteries.
Our carry-on policy provides each ticketed passenger the following allowance at no additional charge:
- One (1) carry-on bag which may not exceed any of the following dimensions: 24” long x 16” wide x 11” tall (including wheels, handles, or any other protruding items), and may not exceed 35 pounds in weight.
Passengers may also carry:
