I doubt they spent all that much money on a boarding system, and they’re probably just fine not having to use it.
It wasn't just the app program, which probably did cost quite a bit of $$$, but they also built and installed numerous digital signs/displays in various locations around DL park for people who don't have smart phones. They were pretty large. They removed them about a month ago. I doubt they are glad they invested money into a system they didn't ever use.
