So there's no technological reason why Alaska Airlines doesn't offer callbacks on their standard customer service line. It has to be a conscious choice. Why would firm chose to make life so uncomfortable for their customers? While I can't prove this, I strongly suspect that the system is deliberately designed to be inefficient for the tier of customers who call the standard service line.
Why? Because calls take a long time, and agents are expensive Some of the airlines are now charging to speak to a live person. Last fall, for example, the American Airlines luggage office was closed by the time my flight landed and I had to pay American twenty-five dollars to be told that they had lost my luggage.
