*There's something darker going on as well.* Some of the inconvenience that US travelers are suffering is built into the system on purpose. Sales platforms are convenient by design because companies don't want to lose sales. Customer service platforms are inconvenient by design because the sale has already been made. Inconvenience makes people go away– and making people go away saves money.
Here's an example. As I mentioned, the hold time today for rebooking assistance with Alaska Airlines is over nine hours. While call-back technology is readily available, #AlaskaAirlines is not offering call-back; you have to stay on hold the entire time. Causing failures to compound, modern cell phone systems are not designed for calls of that length and frequently drop before an agent is reached.
