The Fandango app has an option to check the seats at all the showings at a theater, so I assume AMC has something like that. There are ~600 AMC theaters in the US. Throw in some caching and you can maintain a fast, fairly fresh copy of their seating numbers. Clever!
Yeah, I assumed something similar. Still, it is refreshing to see a website work so well.
AMC seems stingy about giving access to their API. I wonder if this site scrapes data from the AMC website
