You can use the sunflower lanyard program when you're departing from Seattle to Ontario and need assistance at the SEA airport. This program is available to passengers with hidden disabilities who need extra help with check-ins, security screening, and carrying luggage. If you'd like to use the service, you can request sunflower lanyards at the pre-security information desk, between checkpoints 3 and 4, or the post-security information desk in Concourse A.
