Plan ahead
Confirm your travel details. A new requirement is that the name on your boarding pass and your government-issued ID must match. So when you confirm your flight, make sure the name on your airline reservation matches whatever I.D. you plan to use (driver's license or passport, for example). Ask what the baggage policies are for your airline: How many bags are allowed; what the fees are; and what are the size and weight restrictions.  
Pack smart
Valuables and essentials, such as medicine and travel documents, should stay with you in your carry-on luggage. Know what is and isn't allowed in carry-ons and checked luggage, check TSA website for more information. Remember to leave checked luggage unlocked or use a TSA-approved lock (your luggage may be opened for security reasons). 

Read TSA's guidelines on traveling with food and gifts.
At home
Use Web Check-in. Most airlines offer it. You can print your boarding pass at home; if you don't have luggage to check you can bypass the ticket counter completely and go straight through the security checkpoint and your gate.
Check your the status of your flight online.
Give yourself the gift of time. Get to the airport two hours before your flight. Note: Due to heightened security some airlines are asking international travelers to allow extra time at the airport. Check directly with your carrier.
The airport is fully equipped with special access facilities to provide all travelers -- as well as meeters, greeters and airport employees -- with a safe, convenient means of getting around. Please read our accessibility page for more information and visit TSA's website.
Easy parking
Park in the Airport Garage. It's connected to the Main Terminal by covered skybridges (stay dry), you're right at the airport, no shuttle buses to deal with (save time) check out the options - Terminal Direct and General Parking. And the Airport Garage's floor count system takes the guess work out of finding available parking and speeds the journey from car to flight. Remember to note where you've parked (space number and elevator color). 
Public Transit
A number of public transit options are available, including Link Light Rail, which gives travelers a quick, inexpensive and environmentally friendly way to travel from downtown to the airport. Check out the all the public transit options.
Check-in options
Shortening your time in airline ticket counter lines is always a great strategy. New technology offers two alternatives for travelers.
Alaska Airlines “Airport of the Future” Customer Check-In Facility. Alaska's facility features customer-friendly islands of check-in kiosks and bag-check stations. Customers can print their boarding passes and bag check tags at the check-in kiosks. Passengers with only carry-on baggage then proceed directly to the security checkpoint. Passengers with luggage to check proceed to one of the bag-check points, where customer service employees accept bags with tags printed by the passenger.
Checking In for Flights in Sea-Tac's Garage. Travelers on seven airlines – Alaska Airlines / Horizon Air, Delta Air Lines, Continental, American, United, Hawaiian, and Korean Airlines - can check in and print their boarding pass right as they enter the airport from the parking garage. The quick check-in kiosks enable travelers without luggage to print their boarding pass and head straight for the security checkpoint and their departure gate. Travelers with luggage on Alaska Airlines and Horizon Air can get their boarding pass bags tags then take their luggage right to their airline's bag drop area.
The quick check-in kiosks are located on the fourth floor of the garage at the entrances to Skybridges 2 through 6. 
Eat in the terminal
Dine at the airport or grab some take-out for the trip. The options are delicious. Check out our dining and retail options.
Traveling with kids
Sea-Tac's kids area is between Concourse A and the Central Terminal, across from Seattle Taproom. It's a fun-filled place to let children play before the flight.

In addition, there is a Mohters' Room located inside the kid's play room. It offers a quiet, private space where moms can nurse, pump and spend extra time in rocking chairs with their babies. The room has adjustable lighting, several rocking chairs, foot stools, electrical outlets and side tables.

Military families can also access the Mothers' Room in the USO located on the mezzanine level of the Main Terminal.

TSA Security

Long Line at Security?

You can get to any gate from any checkpoint at Sea-Tac. If the line at one security checkpoint is formidable, find and use the checkpoint with the shortest line.

Heightened Security

If it's been a while since you've flown, you'll find some changes at the security checkpoints.
More information on the use of full body scanners is available on the TSA's website.
Please read the Security Travel Tips page for more info.
