Alaska Airlines recommends arriving well in advance of a flight to check in at the airport, as well as bringing the right travel documents, which may vary depending on whether the flight is domestic or international. For domestic travel, travelers age 18 and older need a valid photo ID while for international travel, a passport is required to check in.
Unaccompanied minors will need to have a guardian contact form in order to check in, along with proof of their age.
When traveling with pets across state borders, all animals except guide dogs must present a valid health certificate dated no more than 30 days from the current date .
Not every traveler with Alaska Airlines is required to check in at the airport. It is also possible to check in online or from a mobile device from 24 hours to 1 hour before the flight.
It is also recommended by Alaska Airlines for travelers to familiarize themselves with baggage rules. Carry-on bags must be within 10 inches high, 17 inches wide and 24 inches long. These limitations include wheels and handles. To avoid additional charges, the length, height and width of checked baggage must add up to no more than 62 inches. It must also weigh less than 50 lbs. It is advised to keep valuables in carry-on baggage, since many items are not insured for damage or loss incurred when in checked baggage.
