I have purchased a flight from Ontario, Canada to Seattle, WA. I have had an injury and disabled, and was wondering how to request a wheelchair?

You can ask any airport employee and they should be able to have one brought to you fairly quickly. If you ask, they will also bring you to where you need to go! I hope this helps - have a great trip!

You have asked at the wrong airport. This is the LA/Ontario International Airport in California, USA but try asking a gate agent.

Ask the gate agent or ask the skycap at the curb.
