Alaska Airlines supports a "chat" feature with Reservations agents 24/7; you can text them at 82008, or use the "Web Chat" feature on the Contact Us page at alaskaair.com. Agents can assist with basic Q&A and so on, although anything needing payment still requires a phone call to Reservations directly. It even works while in flight, since alaskaair.com is available for free onboard.

For those who have used it so far, what has your experience been like?
