In this exercise, you'll be revisiting the airlines DataFrame from the previous lesson.

As a reminder, the DataFrame contains flight metadata such as the airline, the destination, waiting times as well as answers to key questions regarding cleanliness, safety, and satisfaction on the San Francisco Airport.

In this exercise, you will examine two categorical columns from this DataFrame, dest_region and dest_size respectively, assess how to address them and make sure that they are cleaned and ready for analysis. The pandas package has been imported as pd, and the airlines DataFrame is in your environment.
