First time flying Alaska airlines and it was very nice

Due to circumstances outside of my control the flight was delayed (a medical emergency). As a result I missed my connecting flight to Ontario, California. The Alaska Airlines agents were helpful in changing my reservation to get me to my destination as quickly as possible, so that was very much appreciated.
