Now that Southwest has their prices listed on google flights this script allows you to scrape and compare prices to a manually set baseline. If the price drops you can either email or text yourself an alert so you can rebook at the lower price.
Recommend installing pip to manage dependencies pip install -r /path/to/requirements.txt

I recommend making a cron job or scheduling a batch file to run this every few hours if using the local version
If using the containerized version you can schedule a lambda to run every few hours
Upload image to ECR
docker build -f Dockerfile.dockerfile -t price-checker .
docker tag price-checker:latest AWS_ACCOUNT.dkr.ecr.us-east-1.amazonaws.com/price-checker:latest
docker push AWS_ACCOUNT.dkr.ecr.us-east-1.amazonaws.com/price-checker:latest
Create a new Lambda from the container image in this repo
Architecture: x86_64
Make sure to update the Lambda role so it has IAM permissions to read/write to DDB and read from SSM
Create a dynamoDB table to track price changes. Table's primary key should be an integer field called flight. Add an integer attribute field called price to the table as well.
Add RecipientCell, RecipientEmail, SenderEmail, and SenderEmailAppPassword as parameters in SSM.
Note that all shell scripts may need to be changed from CRLF to LF as Github changes them.
Special thanks to wbyte-selenium-lambda for their script to download the latest stable version of chrome and drivers to ensure compatibility with selenium.
