We've covered a lot of ground in this chapter. We've learned how to find the best airfare data on the web, how to work with the DOM to find the elements we want to parse, how to identify outliers, and finally, how to send text alerts from our code using web requests through IFTTT. While what we've covered here is for airfares, nearly everything we've done could be reused for any type of pricing you'd like to be alerted to.
If you do decide to use it for airfares though, I hope it provides you with many happy travels!
