Notice about Samsung Galaxy Note7 devices
Due to recent safety-related incidents, the U.S. Department of Transportation has prohibited customers from carrying Samsung Galaxy Note7 devices on board an aircraft or packing them in checked or carry-on baggage.

Personal items such as deodorant, hairspray, nail polish, perfume and certain medicines are permitted in baggage in limited quantities.

- Avalanche packs
- Avalanche packs are not permitted in carry-on or checked baggage.
AA-9V, AAA, C, D alkaline, carbon zinc, silver oxide and nickel metal hydride batteries are allowed in checked and carry-on baggage as long as they are packed to prevent short circuiting.
Personal devices (except for e-cigarettes and personal vaporizers) installed with a lithium battery of less than 100 watt hours are permitted in carry-on and checked baggage. Loose lithium batteries are not permitted in checked baggage on any United flight. Each spare lithium battery in carry-on baggage must be individually protected to prevent short circuits. To do this, you can place each battery in original retail packaging, place each battery in a separate plastic bag or protective pouch, or insulate the batteries by taping over exposed terminals. Spare batteries must not come in contact with metal objects, such as coins, keys or jewelry, and you should take steps to prevent crushing, puncturing, or putting pressure on the battery.
In most cases, up to two larger lithium batteries (more than 100 watt hours, but not exceeding 160 watt hours) are permitted in carry-on baggage if the terminals are properly covered or insulated. If you are traveling with a battery-operated mobility device, please see our Special Travel Needs section.
If carry-on baggage is checked at the gate, any spare lithium batteries must be removed.
For the most updated information regarding lithium batteries, visit SafeTravel.dot.gov and the FAA’s website.
See the Lighters, matches and e-cigarettes section below for information about e-cigarettes and personal vaporizers.
