St. Louis Lambert Airport Passenger Data

Our city’s airport posts data on how many passengers travel through the airport each month and year. It’s posted as a PDF but the data is hard to use in that format. I grabbed the data and put it into a better format:

Why not convert to a graph too?

I’ve posted this data on GitHub. It tells an interesting story of how the early 2000s was tough years for Lambert, but recent years the demand has ticked up. What other insights can we glean from better open data?
